If you can get a head and cam combo that flows enough on a 3.2 like that, 20 psi would run preeeetty strong

Without a high flowing top end on those 3.2's I suspect the low end torque might be mistaken for a diesel engine

Well the way I understand it the engine has actually been designed to be over square (but not to the point that flame propagation becomes an issue) and very light internally so more of a high revving track slag than torque monster. It certainly feels very free and light when you drive it, revs pick up ever so fast and easily.

It’s got the 2.7 head with the larger oval inlets anyway, then its all ported and polished with the inlet manifold ported (to match the inlets) and polished as well. Throttle body has been lightly modified to improve flow as has the intercooler (which is due to be replaced by a custom front mounted item I’m having made for me).

To be honest you have to remember that Paul’s 3.2 was far from finished when he had his unfortunate brake failure, the damn thing was still running a totally standard exhaust for starters!! When you went out in it you could actually hear the pressure inside the exhaust under the floorpan! The engine was trying to breath through straws! Its no wonder it couldn’t flow the air for a free top end.

..You just might be right in the end, only time will tell but I’m pretty confident that these engines will at the very least match the torque figure with hp.

Ps No my turbo is nothing like the lovely ball bearing, cleverly designed turbo Paul has. Its just a simple Simon big and basic design (which I think is why it feels so different when it comes on boost! It still spools straight from idle but mine comes in very suddenly like a double barrel donkey kick to the chest, Paul’s car is much nicer much more subtle and smooth when it launches).

Duke

Sounds very promising Ben, I will follow your engine closely

First figures hot off the press from Jon at 9xx. I knew it was getting on the boost early 1600rpm!




Yesterday we set up a running in map on the dyno dynamics rolling road here in Bournemouth, to make sure Ben's next 1000 miles are giving the engine a perfect mixture.

Power figures for this running in map were as follows...

10 PSI of boost which is set to creep in smoothly
287.8 BHP at the flywheel @ 4800 rpm
330 lbs of torque @ 4200 rpm

It starts to make boost at 1600 rpm (thats when it first makes positive pressure.)

This was with a standard wastegate, for running in purposes.

When do you get more boooooost?

This made me laugh for 5 minutes straight. And I used it as a sig line on another forum (giving credit to you of course).

Sounds amazing btw.

Ben,
Great write-up my friend. My 951 is hopefully 3.2 number 3 and your account was the pick-me-up I just needed.
By the way I've just sent you a PM.
Cheers
Mike

So Ben, have you picked the car back up from Jon's yet?? Jon obviously believes in the older running in procedures over many miles, but at least you're in good hands and he's set it up so you can't make any mistakes with that method.

nick_968

What was your running in procedure Patrick.....? 1.4 bar from the offset??

333pg333

I like Corleone's method. Drive it like you stole it!!

Duke

Nevermind the boost we need more revs
Or preferable - both

Diver944

Sounds like you need a new avatar Donkey boy



I believe he's actually picking it up and driving it home this weekend, and I'm going down on Friday to see all three 3.2's in the same day - swoon

Opeth

sounds awesome

I picked up the car yesterday afternoon (couln't wait any longer!!) Jon got worried that it was a bit too quick for running in (even at 0.7bar) so has turned it all the way down to 0.2bar for the first 1000miles!! How dare he!! ...on the up side I did 500miles yesterday afternoon and its already scrabbling the tires from 3000 rpm to 4500rpm in 2nd and 3rd! Don't know why it must just be the way the torque is delivered?! I'm hoping to have the 1000miles done by the end of the weekend so I can have my 0.7back! lol.

Still feels very free revving though it always felt like my 2.5 had a bit of resistance if you sat at 3000+ rpm, in this car you just don't notice it at all! Jon's kindly said 4800rpm is my limiter though so I've got a few revs to play with Would still give an S2 a damn good run for its money I reckon! (even with the limited revs)

Regards,

Ben

p.s. love the avatar Paul and I'm sorry but there's only 2 3.2 down there now.

Wow Ben that sounds incredible! Just take your time and follow Jon's advice on the break-in process. If you are having some traction issues now, just wait until you turn the boost up a bit. Watch out, for your car is going to be another beast just like Paul's. Also, I know you didn't list a complete spec sheet for the car that Duke inquired about, but, what is your current suspension set-up and your tires sizes too? I can't wait to see pics and some film footage of the car!
