My Volvo S40 T4 700hp with Holset


VulvaS40T4

Recommended Posts

No updates on my car. Goal is standing mile (1609m) event on 11.7.2015 on Kauhava Speed Weekend. 

My friend has old B4194T engine with opened crankcase vents on block (similar now as T2 engine) and forded internals (same is mine) and also same intake manifold.

Turbo is Holset hx40super with 60mm compressor and 64mm exhaust wheel with similar turbine housing as T3 divided 18# (Schwitzer 1.01A/R).

Cams are 9.7mm / 221 (1mm) degrees. With 2.6bar dyno and E85 fuel he had 630hp/650nm and after that exhaust backpressure rise to same as boost on 2.8bar boost 655hp.

Very wide powerband on his engine when hi dynoed his car. :) This must me most powerful B4194T engine on world with hydraulic lifters top. :D

What clutch setup do you use, I can't find the posts about it?  Also, how is pedal feel & grab height in daily driving? EDIT - saw it on the first page - is that (707/850r disc/ stock flywheel) still what you have?

Now that I am able to tune fuel & timing for load more accurately (currently at around 16.6ms load)I just found the limit of my AP racing setup this morning - peak torque area, around 5K rpm, at 26psi, started slipping.

Yes still 707 + 850r disc and flywheel.40000km and 7.9mm new and now 7.8mm disc thickness.No slip. :) Friend 913hp car has similar disc and 765 pressure plate. 

​I thought about the 765, but decided that the 707 would be good enough for ~500WHP. Also, I wasn't sure that the 765 would fit, since no one stateside has ever tried it. Good to know it will.

​Nice. Since I can't use an 850 disc (wrong spline count) I'll have to see if the 707 can work with the larger OD S60R disc.

It's either that, or buy a Spec flywheel & reinstall the Spec Stage III+ setup.

765 pressureplate needs adapter between block and gearbox to clear gearbox and also modification to slave cylinder. So it wont be bolt on job but will work. :)

Also my friend uses newer gearbox which has also wrong spline count for 850r clutch disc. I think it was some Ford disc plate he was using.
