My turbo SE-R made a lot of crazy power!

Ok so we dynoed the latest set up on my red SE-R at last. I know its been years since I posted but I havent had time to work much on street car stuff over the last few years since I started running in SE-R Cup.

Since I last talked about the car I added the following:

1. Turbonetics 60 trim TO4E in a .60 a/r compressor housing, 76 trim T350 turbine in a 0.83 turbine housing, single ball bearing center section. Housings and wheels ported and extrude honed polished.

2. O2 induction intake manifold.

3. 3" downpipe and Tial wastegate with sort of lame semi merged wastegate discharge.

4. JWT's latest 92 lb injector program with Lighting 80mm MAF.

5. Ported the F-Max/ Turbonetics exhaust manifold and gave it a light extrude honing.

The rest of the set up is very simple and not exotic either.

Off the shelf Turbonetics/F-Max turbo kit with slightly bigger than normal IC
87mm JWT Pistons 8.5:1 compression
Tomei Metal head gasket
Tomei Studs
Crower Rods
DPR light clean up headwork
Oil squirters
Underdrive pulleys
S3 cams
Crane Hi-Fire igntion

The power I am getting is crazy, beyond anyones expectations!

We put down 520 whp@ 7000 rpm and 450 lb/ft of torque @ 5500 rpm at only 20 psi of boost!

At only 15 psi it was over 410 whp!

This was with a super conservative program with a 11:1 A/F with JWT's off the shelf fuel and spark curves. With the reduced backpressure the engine would really respond to more advance and leaner mixture, not to mention more boost!

The clutch could not contain the power and this power was while the clutch was slipping. JWT is looking into ways to build a clutch that can contain this power and still be streetable! If the clutch haddent slipped, the power would have been greater!

So there is still plenty to be done.

We will develop a clutch, play with tuning and cams. I also plan to swtich to a Pro-Tech manifold soon as well. It looks like there will be a path to have an off the shelf parts, non exotic, easily duplicatable 600 whp formula for the SE-R soon!
