glad you said that because that small charger wont make 250 bhp on top of your asperated power of 400 bhp

What makes you say that Dom? I know nothing of Supercharger technology.

looking at the air box and the size of Rotrex charger for sure the pressurised air box will 100% split, run a two piece billet air box that will take at least 20 lbs boost if they want to get anywhere near 650 BHP, plus they will need to use injectors that flow 1000 cc

Dom

This is just a temporary airbox, the final one will be done in CF.

Update for the car itself: looks like Murphy had his saying on the SC unit, it's back at the manufacturer...

650BHP 1100KG car 600BHP/TONNE, whats the secret of how you are going to get that power down?

Sticky rubber for one

Thanks J

Hey Barry,

There isn't exactly a point in posting supercharged engine figures, if the supercharger is back at the factory is there?

So CF airbox and problems with the SC. Do you think that you'll make the May 5th three year deadline? Good luck.

Yes, will be up and running as soon as the SC is back from Rotrex.

Nice one Benny

Dom

What has Benny got to do with this then, Dom?

First name that came in my head

Dom

Your loverboy, for sure?

When did that start then?

Hey Benny

when are you going to post your Hp figures, you keep moving the goal post, how about me and John Ravencroft map your tuscan foc ?


Dom

Hey Barry,

There isn't exactly a point in posting supercharged engine figures, if the supercharger is back at the factory is there?

You was so sure big boy the package you had would make 650 bhp dont talk the talk, pro-charger is the only way forward with the baby asperated power you have


Dom

What is your point here, Dom????

I'm not "talking the talk" here, Rotrex admitted it is a production fault, and the unit is at the factory for the moment to be rebuilt. What more do I need to say???

I gave an update, as soon as I could, as I've been out of the country for 6 weeks in a row, and didn't have the time to keep myself busy with chasing details and putting them on here, as I have a lot of other things going on in my life that require my attention, than the rebuild of a car.

Pro-charger... Never heard of them. Rotrex I know since years on the other hand. So excuse me for trusting in the latter, excuse me for having one of the few supercharger units where the internals break within the first hour of serious use.

My Point is Rotrex will always fail trying to run large numbers trust me on this ive tried, take this how you like just think about this, you need to ask rotrex can they build a charger that will make 250 bhp on top of 400 NO they can’t, don’t use a cool charger WHY because the air they circulate gets to hot, run an intercooler and a pro-charger then your easily make 650 bhp at the wheels for sure.check out the link

Interesting link but that's got a base bhp of up to 325. (Not that I know about supercharging.)

[yzf1070]

Perhaps this link makes it easier to understand.

http://www.procharger.com/models.shtml

My engine is running the C1 and so far the chargers been extremely reliable. I like the none intrusive self contained oil reservoir as opposed to cutting into the engines oil supply system. The charge cooler has proven more than adequate at this stage tho I am not pushing anywhere near Pascals 650 bhp target. Dom's comments of needing 20psi I would suggest are right. But I simply cannot see a 10.5:1 compression ratio engine lasting long on pump fuel, the heat generated will be colossal and I would fear head errosion around the exhaust valves, melt through between 5 and 6 cylinder walls just down from the block deck. Also at 10.5:1 I am boosting at 9psi max and more than happy with the performance and engine heat is more easily managed. Infact the car is damn right brutal and a bit of a handful at times. 3rd gear full throttle over taking has to be performed on really warm tyres and very good road conditions. Forget 1st and 2nd gear full throttle, wheels spin up and the engine revs out far too quickly.
IMHO 650 is a little pointless in such a light weight car but if acheived will be impressive roll on performance from 3000 rpm onwards

[Laser Sag]

JR unless I am misreading the link it suggests it can be used to take an original 325bhp and boost it to 675bhp which I think was Doms point.
Interesting comments about the need for a careful right foot and hot tyres before making use of so much power in such a light weight car.The number of threads you read on here where the car just "swapped" ends with an available 300-350bhp in less than ideal conditions I dont think I for one would fancy the idea of upping that to 650bhp.
Good to note the different upgrades being developed by all parties for our benefit though, but for my part I think when the time comes for a rebuild Ill stick with normally asperated which will be more than enough for fast road driving.
All in my humble opinion of course.

That's correct, a base BHP of 150-325, as I read it also. The point is that a standard 4l S6 will make more than that range, say 365bhp.

On the other hand reading Graham's link, although you'd initially think that a C2 would be needed, I wonder whether that base bhp should be taken after the engine has been rebuilt to accept a supercharger, thus lowering the base bhp. Or probably the base range just isn't that critical.

Graham, glad to see that you're enjoying your car at last. All of these supercharger conversions seem to involve a lot of heartache.

[T40ORA]

I personally think that anyone 'charging these cars is totally bonkers. But bonkers in a good way

I think that I will remain NA too.....

(However I'm chomping at the bit for a ride in Pascals - after I have completed my will-pack and upped the life insurance )

[Laser Sag]

Potentially good precautions Lee,will be interesting to see the end results of these packages but get the feeling that the track will be the best place for 650bhp MK1 Tuscan where at least on slicks it might have a chance of using it all.From all the things ive read about supercharging I think the biggest worry would be how to deal with all that heat as they dont seem to get rid of the heat generated by the standard engines that well.But presumably that is why you spend £20K plus as I understand to have it done in the first place.At that sort of money think I will wait until the 4.5 conversion is needed and then spend the rest on a respray to cascade indigo.
Havent managed to read all the threads on the supercharged TVRs but have brakes and suspension etc been upgraded to cope with this extra power?

[leerdam23]

Surley, for 650 HP from a 4 ltr engine you need to drop the compression ratio down to near 9:1, run it rich a you can on high octain (101+) and have a very efficient intercooler to get rid of the heat generated by the 20psi compression (Ideal Gas law)?

Otherwise melting and detonation!!

OK Guy's I just cleaned up the crap muti quoting, is it really necessary to ruin a thread in this manner? I cleaned up and just left the last one so all posts are contained.

Lets keep the quotes down to a minimum please, I really don't want to waste anymore time on this type of activity.

TYIA.

Thank You Jonathon and you are not wrong about heartache. Its taken since July 2005 until October 2009 to get it properly sorted. Including buying the car for 30K in 2005 it has cost a further 65K in x2 rebuilds, new parts, mods, dyno time and labour. That includes the first failed rebuild engine which took more than 18 months to do and only 3 months (2000ish miles) to fail. The STR8-SIX rebuild has been better having clocked up 4800 miles now. In an attempt to prevent heat related failure, knock and EGT sensors are fitted and hooked into the Link ECU. Since I no longer live in UK I seldom get to drive it. Looking forward to a dry June tho when I will be back behind the wheel again....Lakes, Aberdeen, Hull, Mylton Keynes, Essex and Sussex.... oh and a new AA membership

[Laser Sag]

Graham you must either be single or have the most understanding partner know to man.My missus just informed me that if I tried to spend that sort of money on the Sag I would be out on my ear.I suppose the good thing is that I can now try to persuade her that £10K on a 4.5 conversion is a bargain.
Really hope you get the weather to enjoy it in June.

[i remember]

Just like to pop in and say, you are a ledge and this tuscan is awesome! keep up the good work

I married a Filipina. South east pacific asians make superb wives. Worst thing we ever did was give our lot the vote and equality.... went down hill after that. Part of the reason why UK no longer has an industry left is because of one of them having power. Mind you the donkey in there now hasn't a clue.
Anyway this thread is about Pascals S/C FFF and I can't wait to see the results.

Oh - so it isn't about Dom's opinions then?

BTW I had to steer my wife away from the laptop as I was laughing while reading you female vote comments.

Think I might make a wee visit out there
