Mike i think you really need to think about where you want to end up unless you have an endless pit of money!!, the ajp is a very nice engine indeed and i would love to get my hands on one as the power potential is excellent 500 bhp and more, however this is the same sort of thing as getting big numbers from the rover you end up sacrificing the driveability, on a personal front i would definetly go for a blower set up with what you have, cut a long story short the engine i built for austec for martin's twin turbo ended up in a friend of mines griff!!, unfortunetly the blowers werent brilliant nor the instilation, thats all been rectified by clive at prism motorsport and on dave walkers rolling road it was making 650ftlb of torque at 3500 rpm, unfortunetly he couldnt get a bhp reading his rollers just couldnt cope, makes sense to me to put some blowers on it!

christ that's a big number at 3500 Rob. How on earth does that feel on the road? must be manic Is this the griff dave mapped a few months ago?

Extremely impressive and scary stuff!!!


Can someone give this man an AJP??? Mongoose? how about yours? Doooo it...

Forced induction is certainly the way forward imo. All that toprque to play with and it needn't be to costly.

But surely, with turbo(s) you must lose a lot of that lovely V8 woofle?

Not really, there's still a nice woofley note with turbo's and when the throttles open the sounds really amazing. A very solid bark! It rattles shop windows

The outright roar of the v8 goes as such but it sill sounds pretty good to me, to be honest i prefer it because you get that really deep note like a big american engine, i think what impresses me more than anything else though is the driveability, seriously this things drives like a pussy cat around town, no jerking/hunting etc... due to wild cams but still makes huge amounts of power!!

With that much power I wouldnt GaS if it sounded like whoopee cushion..

Are you getting close to a product Mike?

Turbo engine build stuff has always been ready. The external conversion stuff has to be tiff bespoke so I've designed the cast twin turbo headers but would prefer to have a customer on board before I sink money into production. Development can be quite expensive. A single hybrid turbo (for a single turbo conversion) was built up and Joo's got that to test fit into his 'S'. This would be an entry level option say 300 hp. The TT option would be over 500 lbs/ft and maybe a bit less hp all depending on specs ordered.

Mike the engine specs for the engine mentioned above are basically, 5 ltr, billet crank forged pistons, steel h beam rods, mild cam!, 500 heads, and an after market system, it has certainly made me think about blowers as opposed to chasing your ass with n/a engines!

with a turb'od griff wouldnt there be lots of issue's were is the intercooler gonna be fitted ?or would there not be 1 fitted? and with all that extra heat you'd have to wear an aspestos suit to drive the thing
let alone it staying cool. not that i dont think its a great idea just struggling to see how it would all work out

I will take some pics next time i see the car, but bassicaly no there is no over heating probs at all, it does run an intercooler etc... i will get some pics...

I'd place an air to air intercooler up front and also add water injection nozzles into the plenum. Turbo's would be in front of the engine and you could duct air around them, or vent the bonnet or just use heat shielding where required.


Rob, I imagine you'd have had reasonably high c/r with that. FI has always appealed to me ever since I had the experience of a valve kissing a piston many years ago and because they were bespoke it was a pain in the butt replacing one valve every now and again. You can achieve pretty good results from a stock 4.6 or 5.0 so long as you don't go mad with the boost

Wouldnt turbos scavenge some of the heat away compared to the catalyst elements heating up in that area?

Noise / heat ..... I'd auction my goolies for 500bhp

Dave

This is not a legally binding offer - you b*****s

[petepetrolhead]

If you can't get hold of a Cerb speed 12 lump , then I'd go for an RV8 with supercharger - then fit some nice cherry bombs so you can't hear the whine! Although I do like the sound of a flat plane crank, it doesn't do it for me like a good 'ol classic V8...

MongoseMike might be interested to know i was speaking to Jamie a CRE today .. we had big smiles talking about the AJP8 into Griff scenario .. it's got to be done!!! The best engine TVR have into the best looking body TVR ever made. It's a winner! Just imagine it .. 420bhp, 7500-8000rpm potential .. that gorgeous Cerbera exhaust note, that instant throttle response .. I'm going all gooey just thinking about it

I've done a Rotrex conversion on an 4.8 rv8. The blower sits in front of the n/s head and makes 6 psi at idle, enough to blow your hand away from the inlet tract. I prefer turbo's but some like blowers.
