REW Sequential Dyno - very uncommon results

***TitaniumTT*** · 09-27-2009, 10:55 AM

I figured I put this in the 3rd gen section as you guys would have the most interest in the project, results and have the most informed critism.

A quick rundown of what's involved here
13B-RE block and mani's. Rebuilt, cryo'ed and ported.
Intake ports were SMP med intake that I spent hours cleaning up the bowls and runners. Portmatched LIM to block, UIM to LIM
"Cosmo" housings with REW sleeves and I used the Pineapple Race EP2A template.
RX8 eshaft and stat gears
S6 rotors

Turbo's are bone stock REW sequentials run non-seq (for the time being, going back in a few weeks to get the seq working) with the exception that I had everything ceramic coated from Anthony Bulger - Street Tuner and I modified the y-pipe to elimate the stock bypass valve and my own efini style x-over pipe.

I built my own HMIC setup and modified the standard Greedy TB Elbow to suit my needs

Running a Motec M820 and using Rob Bailey solenoids to control the sequentials.

Running 93 oct, OMP injecting Idemitsu premix and running about 1/3oz/gal in the tank. After 2500 miles the compression is still rock solid and hasn't fallen off at all. It seems to get slightly better by maybe 1% so I believe the ratios are right on the money.

So, what are the results? I was actually VERY surprised. Using the Motec's datalogging we were running about 160-165kpa which is ~8.7-9.4 lbs of boost. Call it 9lbs. At 9lbs of boost running non-sequential but all of the sequential hardware in place Dave @ KDR and I made 328.88 RWHP with torque climbing all the way to 6800 and hp not starting to fall off until 7300. Current redline is set @ 7500. Pretty conservative timing and running .8L or ~11.7 afr.

And a vid

Has anyone ever seen numbers this high using the stock twins at that boost level? I have plans to go back to KDR in search of 400 RWHP @ 15 lbs of boost with the sequentials working. They'll work, we just need some time on the dyno to get them sorted out and functioning properly. The highest that we've seen was 402 with the stock twins. However, that was a half bridge motor running 18lbs of boost. The turbo's lasted 300 miles.
