Finally the beast is 'tuned' to my satisfaction

I might question the use of ‘the holy hand grenade’ approach for terminal velocity but each to their own, same applies to I.C.E. for me, it is capable of drowning out the noise of the HSV at speed and it does not hurt as its got a distortion free sound, no way will it compare to a home system pound for pound but then home systems don’t offer dedicated SatNav with the option of passengers enjoying a movie to the driver enjoying music simultaneously. The added weight (250 KG) helps keeping the rear end planted. So in line with caspy’s comment you have maxed out at 260 mph then? Just having a laugh based on 40 mph/1000 revs and 6,500 limit. Do you use Road Angel for the likes for accurate speed info? I have used a top line Garmin system and the RA together at speed and we are only talking of 1 MPH discrepancies. I can only rely on RA as I am over sized slightly on tyres (245/40/18). Quite agree with you about looking at the speedo, above 150 I cannot look at the instrument binnacle & have to rely on passengers for what speed were doing, mind you my Garmin unit logs the highest achieved speed

I really dislike Superchargers hence the NOS, but am about to have a Turbo fitted if the Tuners install on his own car proves successful. Will keep the NOS having said that, I currently have circa 500 normally aspirated BHP plus 250 with the nitrous install. As you rightly say 'each to their own'

As someone who has never even had a radio on whilst driving I find in-car 'entertainment' stuff a bit odd so please forgive a real Petrol Head LOL! I do use SatNav though. The added weight is a sure-fire way to slow down acceleration which is what I find odd about ICE installs.

I have maxed out, do not know how fast except 'very'. See post reference to speedo reading I have a KAAZ diff so could work it out I guess.

I use STACK in other cars not Road Angel, thinking about it I will put it in next time I'm at the Nurburgring in it.

Out of interest were your power figures recorded on a Rolling Road?

Hi oe cosgrove

Good reply, fully understand your view point. I am not such a serious enthusiast as yourself and will bow to your experience as my experience only lies with the HSV, I doubt my experiences of smart cars will count, probably have you in fits of laughter by comparison as even with NOS your car is not as powerful as my 700cc smart on a power per litre comparison, the torque comparison will probably be a greater differential too.

Would love to know what your terminal speed is though as some have claimed it reaches a brick wall at 195 and getting past 200 is going to be difficult to say the least.

Be lots here interested in Turbo applications.

Dyno Dynamics rolling road at LSV
Back to the ICE, sometimes I do cruise at 55 on long runs, holidays etc and the ICE really helps out on such occasions, TV is good fun in traffic congestion too. So if I stripped out the ICE etc I would be 250 KG lighter & I would guess a second or two quicker to 60 & 100 but then I am happy with 9 seconds to a 100 even with all the excess weight.

I have a mate with a 'Tuned' Smart and know exactly what you are talking about Trouble is I would need one for each foot LOL

Aerodynamics play a huge part in top speed. I have ordered front splitters and rear diffusers plus flat bottom plating. Certainly my car does 'over 200 mph', I'll keep you informed if you wish?

The Turbo install will be done by Monkfish Performance in Brackley. Only discovered them recently and must say they are the best I have used in over 30 years of spending silly money on cars, even compared to certain German companies!

See my post in the North West section on Rolling Roads. Trust me when I say the figures are questionable. Happy to drive alongside you with 'equal BHP' to prove the point.

I take your point about ICE but will stick to bladdering EVOs etc in a straight line

[V8HSV]

Bladdering EVO's makes me laugh, I like pissing off Audi, BMW & Merc owners on motorways, maybe that’s why I had 11 points not to mention fast bikes, yes they pull away but I can still reel them in, not found a biker yet that will stay at high speed for long

Yes very interested in your turbo application by Monkfish, great outfit, well supported by those on this forum, great customer service, so unusual in this day & age.

Used to comments about the smart, when does the other half arrive, they are electric are they not to, have I pinched you disabled spot etc

Are you going for the CAPA style splitter, the one that goes right underneath the engine bay? I have always wanted one.

Agree on rolling road figures but I am used to hours spent on a hub system which I believe are very accurate and when the car had fuelling issues running without a MAF sensor it was still producing 450 brake & 500 ft-lbs at the wheels and will be going back to Abbey Motorsport one day for comparison.

Thanks for the offer of a drag race but that’s not me otherwise I would have been to the pod before now.

Yes, would love to know what speed you have achieved, might be the benchmark for us all. Remember I am running mine really in a de-tuned state, I know I could easily achieve another 70+ brake by upping the boost to 12-13 psi.

Nice to have some friendly banter here as things have got a bit prickly of late keeping the regulars too quiet.

Those are some impressive figures. I'm currently trying to convince my better half that an exhaust and tune would benefit the MPG. She's not buying it. lol.
A friend asked me last night when I'd be fitting the blower and I jokingly replied "after the exhaust" - unfortunatly her comment was something about leaving me.

Keep up the good work guys - I'm envious!

I own.....and love....EVOs but get great pleasure passing owners who think nothing is faster Mine is an EVO 6 with 400 (real) BHP. Same with Mercedes and (YUK!) Scooby drivers. I'm an ex Bike racer and had quick ones on the road until an accident put paid to my love of 2 wheels My HSV is quicker than a Hyabuser or Blackbird.

Front splitters will be Porsche Cup type which I have found to be the most effective. No experience of CAPA.

See my comments on hub dynos too. OK for testing cars are producing 'similar power' but accurate? Nope. If static dynos could be used to fully set up engines track testing would not be needed. Even Clayton Brake set up engines require track time as road conditions cannot be accurately recreated. The only reasonably accurate power figures though, prove US, Japanese and Australian horses are much smaller than British ones LOL

Your comment about the potential power with your supercharger is why I dislike them.......for less money I can have a real 550 to 850 BHP+ and a proper big single turbo for optimum torque, plus the NOS will make it awesome. For under 3K I have 750 BHP with a NOS install which is why I took that route.

I wasn't asking for a race, just a side by side drive with my NOS dialed in at similar claimed power Not trying to score points, anyone who has done what you have deserves respect from us old Petrol Heads

Best Wishes
Paul

[V8HSV]

Old Petrol Heads, blimey I'm 49.

You have beaten me fair & square on the money front, everything looks different with hindsight, you will probally have lots of people asking you can I have 750 brake for £3k now LOL

Not sure about turbo application, I need 6-pots to stop the smart if the boost is still on when I'm trying to pull up quick, that would be too frightening for me in an HSV, imagine pulling 3 bar with a 5.7 litre LOL

I doubt you are alone, I have heard of one spending thousands before the divorce goes through - titter

I am now not encouraged to do any further modifications, just as well I have done about all that I can. My previous marriage wenmt 'tits up' after saying, well I'm buying it anyway - oops!

A friend at work recently came in with a black spray can, his yellow strut brace arrived later, 'she will not nottice it black' LOL

[308mate]

Sorry, for as minute there I thought you said your ICE weighs 250kgs?!
The equivalent of having 3 average size blokes in the car all the time. Im very sure Im pointing out obvious stuff here but jayzus, your recent performance increase (in ETs - obviously not HP) could have been achieved for free/nada/gratis by simply removing half the ICE.
None so strange as folk...

PB

[V8HSV]

Now I thought you boyz liked power, the weight is comprised mainly of two batteries giving 215 amp-hours together, enough juice to run 1,000 watt amp & 3 DVD screens at w/e shows plus green underbody neons & front headlamp strobes, each to their own as they say.

[308mate]

Ahh..I think show cars have special dispensation as there is an expectation (rightfully) for them to be visually exciting, aswell as having a performance aspect. Not sure who would have licensed the underbody neons though...

With regard to your comment about not having met a bike rider who will hold max speed for long periods - we have a saying:
"You will old riders and you will see bold riders...." you know the rest.
Although I did hear a vicous and unfounded rumour *ahem* about a couple of blokes who clocked their '05 R1 and '05 GSXR1000 for a good portion of the M27 early one Sunday morning...

Given that the cars are over geared in 6th, would assume it is natural progression and far cheaper!!

But 6th is intentionally tall for cruising.

I can smoke the tyres in 1st thru 3rd in the dry, pretty much at will. Why shorten the overall gearing and add 4th gear to that ??
When you have a lot of power, tall gears make sense, and quite often acceleration actually improves.

As for Mr Turbo/NOS. I'll admit I'm sceptical about anything other than a properly built LS1 engine handling a 250 shot for very long without damge. That is an awful lot of nitrous to be throwing at an engine that is only making 500bhp. I say only, as its a whopping 50% increase over n/a which is a lot.
I also imagine that unless you have a pretty big bottle, the gas doesnt last very long either.
I know when I fitted a kit to a friends 2.0 some years ago, his 75shot only lasted about 2 mins total from a 10lb bottle.

NOS has its place, and thats for the drag strip. It just doesnt last long enough for road use.
As for aiming for 800+ with your big turbo, which is very achievable, I think you will also have some very serious traction issues. That is exactly why I chose a centrifugal blower over a turbo.

I dont see why a genuine 200mph + should be that difficult to achieve with a bit of power. I'd say Monaro's are quite aerodynamic.

Blueprinted engine and yes specifically for drag strips / airfield top speed events. I have twin 10lb bottles, twin solenoids and a Maximiser for progressive power so the nitrous doesn't hit all at once. The engine is definately strong enough for this application, 25K miles and no problem to date on it, car has done 44K. Traction is OK on Micky Radials. I'll be using it on an 850+ BHP AND Nitrous engine after the turbo install, will report on longevity then LOL Its an HSV not a Monaro.

Do you use the MT DR's on the road ????

Whats fastest time so car, and 60ft with the DR's ?

I wasnt at UFC or USC, so dont know of the Porsche....

[Boosted LS1]

oe cosgrove,

Have you changed your pistons or c/r?

Boosted.

Am doing for big turbo install, yes. Smaller version runs on OE.

[stevieturbo]

500bhp, + 250 shot, and standard CR, with standard pistons, and it has survived ???????


Whats done to achieve 500bhp in the first instance out of curiosity ?

oe_cosgrove said:

I have maxed out, do not know how fast except 'very'. See post reference to speedo reading I have a KAAZ diff so could work it out I guess. I use STACK in other cars not Road Angel

How would a KAAZ diff tell you in any way what speed you are doing, or allow you to work it out ? KAAZ is simply a brand name for a maker of LSD's

Is your Stack system GPS based, or based on electro or mechanical signals fitted to a rotating object ?

I'd be inclined to take GPS based speed reading as more reliable than the other, as the other is open to user error.

Yes it has survived.

Cam. Decat. Exhaust. Headers. Remap. Induction upgrade. Monkfish upgrades. 6'1", 32" inside leg, going grey now. It is an HSV not a Monaro.

I could work out potential top speed with KAAZ diff using its ratio.

I havent a clue which Stack I will use. The opposite to the one you regard as best I would guess

[stevieturbo]

KAAZ is a limited slip device, it in itself does not have a ratio and does not affect teh cars gearing, hence I queried your comment. Your cars crownwheel and pinion have a ratio though, regardless of actual LSD type.

Pedantic, I know.

I didnt reccomend, or not reccomend any STACK system. Ive never used their products, or felt the need to ( or had the money to waste on them ).

I simply pointed out that a GPS speed measurement system isnt open to user error, in the same way virtually any form of mechanical/electro measurement can be.

Good luck with your turbo project, it will be an awesome project. Look forward to seeing you, and maybe even racing you at TOTB5.
It would be nice to see a lot more road cars of differing brands there.
