That's how it's done. The fun doesn't start 'til 1.5 Bar

What's the spec?

very nice!!!! - what's the torque steer like?  

[foggyjames]

That figures - power wise, I see the key elements being...'built' motor, GT30(71R, perhaps?) on a good manifold, a good tune (good to see a standalone system on a T5...not that it really matters, but it's relatively unusual)...and a little more boost than the gaggle of 400-450bhp cars I know of.

A good cylinder head makes such a difference. Ryan's 740 is essentially a very similar concept (besides the tubular manifold), but the (standard 8v) head flow severely blunts volumetric efficiency to the point where for essentially a similar spec, we're only getting somewhere in the order of 350bhp. A 16v conversion is so very tempting...

Anyone know where it's redlined? I'm guessing it's another 8k+ motor.

Hi Pangster

All i can say is i am glad i went for a gripper diff over a quaife

Hi James thanks for you comment's what i wanted to do with the project was use the best of everything,i looked at which stand alone ecu i wanted to use it was between motec and autronic, in the end i went for the autronic as it has lots of standard features which are all extras in the motec

The head and a proper manifold are the main key bits as you rightly say to get the power so easy,i am currenty having cams made from steel billets with a fresh profile selection Which i hope will improve things even more the revs are set at 7k no more is needed yet

ROFL!!... it sounds and looks awesome! - wish i could see it in the flesh! lol!

what other plans do you have for it??.

[foggyjames]

If you wound it out to 8000-8500 with those new (I'm guessing hotter?) cams, I think you could add 100-150 BHP to the total. I'm impressed that that's 'only' at 7k!

cheers

James

[BlackBeast]

So when are we going to see this custom inlet manifold? i.e an ME7 manifold with the flanges cut off and pre me7 flanges welded on?

I have many jobs left to do its still all under way i want to see for my self how far you can push it if you go to any of the usual car shows your bound to see it soon enough

Hi James

I am hoping i have gone the right way with the new profiles there is much incorrect info on the net from people that are good at guessing what is good and no nothing its a big learning curve for me but i love every minute of it

Once i am happy with the cams the next step is race fuel

Hi Steve

I am not sure yet it may not be what you think i have many bits left to do

Hi Russ,

Oooh! More timing, or more boost...or both? I've been very surprised by Ryan's 8v (not a chamber known for its ping suppression)...we're able to run ~25 degrees of total timing (8 static plus 17 or so dynamic in the map) at 2 Bar of boost...on 95 octane      Admittedly, better fuel and more timing would probably make noticably more power, but he doesn't like the cost of V-Power

I did find the specs once for that 1000bhp T5 motor...but I can't find them now. It uses a D5 block (no more cracked liners!), a turbo that looks like it came from a tank, 10,000rpm and 2.5 Bar of boost. I don't remember seeing any pics of the intake and exhaust manifolds, but it didn't have to fit into an 850's engine bay, so I imagine they did whatever they felt like.

cheers

Hi James

I have a contact with an 850 with 842 bhp :0 and uses a similair spec to the above a pure 1/4 mile car with a space frame chassis with an 850 body i will post some pics

It's always interesting to see what others have done with the T5 engine with real genuine power but they are all seem to out of the uk
