I can't comment.. I might break the rules.. can't say about the 55lbs injectors we do either, or the wastegates.. or all the new stuff we do.. [

I can tell you that we recently got just shy of 500 pounds of torque at around 3500 rpm on a 944 turbo at what appears to be the countries lowest reading DynoDynamics rolling road a few days ago! []

Well I've been in touch with Mark Dalton who owns the number two 3.2L that Jon and Simon built and he is very happy with it after collecting it last week, I know he's on the forum but doesn't post much so I hope he forgives me if I blow his trumpet for him [].
It is very similar in spec to mine except it has a big Fabspeed exhaust which frees it up a lot. At only 15psi he has a Dyno Sheet from Triton Motorsports that has a headline figure of 411bhp and just under 500ftlb of torque. He's only done a few hundred miles and is gingerly exploring full throttle [8D] I can't wait to see the car (just to see if the exhaust is quiet enough for my tastes [] )
When I made the jump from 15psi to 18psi the car gained an extra 50bhp so gawd knows what Marks would do []

]Scott, I have to say in my experience with the Apexi EBC that it has some nice features but getting it to be consistent was very difficult. I know that it's a favoured product in the Modified Japanese car field, but you may need one of them to tune it to it's best advantage. We have gone back to an MBC and it's perfect everytime. Perhaps it doesn't get the absolute 100% best out of the setup like the Apexi could potentially, but I'll settle for the same boost (1.5 bar) to hit all gears everytime.
Interesting post. You run it with knock regularly and reach 1 bar at approx 3000rpm with a LR75 on a 2.5L with stock airbox and i/c?ORIGINAL: Sly
2,5L + 75lbs injectors + modified WG with stronger spring + modified snorkel + 3b fuel régulator + forge dump valve + big valves intake and exhaust + full LR 3" exhaust + LR75#8 T350 + VR MAF + VR piggy back + accuboost + bosch WR5DC sparkplug.
Stock intercooler, stock airbox, stock intake line after turbo
Il run 19-20 psi boost with some knock between 3500 and 4500 and after 5500rpm.
On 5th gear :
- 9psi at 3000 rpm
- 15psi at 3200 rpm
- 18psi at 3300 rpm
- 20psi at 3500 rpm
- 19,5psi at 4000 rpm
- 19,5psi at 5000 rpm
- 19,3psi at 6000 rpm
- 18psi at 6500 rpm

John at VR tends to run things on the rich side when it matters (as a generalisation). This is one of the reasons why he will run with 72lb and 83lb injectors. I've currently got one of his Stage 5 kits (83lbs) on my stock 2.5L motor and it idles pretty well. We could make it idle better but this is an interim motor (I know, for a long time now []) and I'm running E85 everyday. The advantage of this is that with the E85 I also run 1.5bar and there is no knock. The 83lbs help supply enough fuel for this purpose. You need approx. 25% more fuel when running E85.
The twin inj or staggered setups are there primarily for high hp race motors. We thought we may have to go to this extreme on my motor that is almost done now but we have a modern set of 160lb inj and have got them to idle fine on US 93oct pump fuel, so it can be done without the 2 per cylinder. This is with a Bosch 044 pump and a 5 bar fpr. It will be tuned with 2 maps for both normal fuel and E85. With E85 we will be able to run 30+psi safely but that will be too much power for this car. Of interest will be what power / tq it gets with being able to run 1 bar all day long? Should be soon....I keep repeating....

It would be nice to see Mark-D in here, but he is a busy chap.
The exhaust is not as loud as you would imagine, in fact, I would go as far as to say its a little louder than yours at idle, but quieter than yours when on boost.
The real potential of the 3.2's would require some ignition upgrades, intake manifold, throttle body and some serious intercooler.. Not to mention a camshaft which I am working on.
I think we are at almost peak torque now at reasonable boost levels, but for peak BHP we are still at very early days. It would be nice if one of the 3.2 owners wanted to explore this further, but I can understand if the vast amount of torque the owners are getting, that they may choose to be content with what they have!

More than content, oh yes [8D]
.......but there's maybe, always room for a leetle bit more [
] We'll talk further at this years service [:-]
Jon, there are some very good cams already available out of the US and not too expensive especially with your pound. They're ground from fresh billet and you could get them made to your specs I'm pretty sure.ORIGINAL: Indi9xx

Off the shelf ones are not suitable for the 3.2 and the ones for the 2.5 are a bit of a compromise (one size fits all spec's type mentality)
My 2.5 cam spec has taken some work to formulate and I don't want to hand all that work over to what will effectively be a competitor. The 3.2 cam is another item with a different delevlopment path.. All will become clear a little later this year.
Also not happy about the quality of the ones I have seen from the USA.

First 3.2 to go for wasted spark programable ignition gets free fitting and dyno setup!
First 3.2 to go for a camshaft, gets free fitting and free dyno setup!

If it will make the wallet creak open, Its rumoured that I might be able to do a good deal on a 3 inch exhaust.
Not only this... But 3 inch from the turbo back including the turbo discharge pipe, unlike the commonly available ones which are 3 inch after the turbo discharge pipe. (also a rumour)
Word is that we can also add an extra free flow silencer to the mid section to further reduce noise should it be an issue.
All of this is 3rd hand info of course.. otherwise I would have to protest that I was advertising or something.
Interestingly... I also have some options opening up for an intake manifold especially suited to the 3.0 and 3.2 turbo hybrid engines with a specific feature I have not seen in any other performance 944 turbo intake manifolds.
I wish I could shout about some of the bits we are working on at the moment... But its not the place []
