ChuckV Posted June 16, 2004 Report Share Posted June 16, 2004 Buddy of mien claims he has a friend who rides a 2.5T with 23PSI. Is that ABSOLUTELY impossible (Comp ratio) or CAN it be done?If so, what would u have to do?I suppose excellent tuning with a much larger than stock turbo and race gas could run that. I dunno about reliability though. That's A LOT more strain on everything than stock, even with perfect tuning. Link to comment Share on other sites More sharing options...
volflo Posted June 16, 2004 Author Report Share Posted June 16, 2004 he claimed his max torque was 600Nm. Well, i think then, he did it. he also redid his calinderhead and the valves. Hopefully i am going to see this car ba the end of this month. i will let u know then.Maybe it was a misunderstanding and he just increased bore of the 2.3HPT to 2.5? Could it have been that?

550 Posted June 16, 2004 Report Share Posted June 16, 2004 Wow that is alot of PSI, oes the 2.5 engine have thicker cylinder walls? I always thought a reason not to bring the boost up so much is that you could more easily run a rod through a wall, or bend it. But I don't really know for sure on that.That I bet is one quick car.

I always thought a reason not to bring the boost up so much is that you could more easily run a rod through a wall, or bend it. But I don't really know for sure on that.That I bet is one quick car.Rods USUALLY go because of detonation. Though running high boost, especially in a high compression motor, puts a lot more strain on them than running low boost does. In the case of the Volvo LPT motor, the main reason for not running serious boost is the high compression which makes creating a detonation free high boost environment much more difficult. Upside of higher compression is much higher torque, and quicker response.I really couldn't see him running that kind of boost on the stock turbo. 13Gs are pretty small... New heads and valves are helpful of course. Running that kind of boost, a valvetrain overhaul is pretty much required to keep things reliable.

Guest Guest_PyroTech Posted June 16, 2004 Report Share Posted June 16, 2004 i am sure that running serious boost is possible. It just a matter of time before something goes. Link to comment Share on other sites More sharing options...
volflo Posted June 17, 2004 Author Report Share Posted June 17, 2004 hi runs a 19T and redid his WHOLE engine. head, pistons, rods, N/A cams, manifolds. 600 Nm..... how much is that in lbft??????? Link to comment Share on other sites More sharing options...
550 Posted June 17, 2004 Report Share Posted June 17, 2004 600Nm x .738Lb/ft(2) = 442.8lb/ft(2) Link to comment Share on other sites More sharing options...
olosports Posted June 21, 2004 Report Share Posted June 21, 2004 i've run 23 for 2 years now in my t5-r 2.3L Link to comment Share on other sites More sharing options...
Guest Guest_the poi Posted June 30, 2004 Report Share Posted June 30, 2004 the 2.4t isn't really a "high CR" motor... its only 9.0:1. The walls are thinner sure, but the rods are the same as the HPT. Unless he's bubbling the cylinder walls, then theres no reason why it shouldn't be possible.(hell, in a couple years, im gonna be runnign 25psi on a LPT motor....if it kills me ) Link to comment Share on other sites More sharing options...
