9sec9/OKIX's EVO, ROUND TWO!
.
Hi Tom,
Looking very nice indeed, professional.
Good luck at the track, now Tony's driving has just got to bring her home. With all the work that you have put into this car, it really does deserve to be in the 9 sec bracket. Barracking here from Oz for you guy's.
Cheers Steve

Thanks to all of you. I'm making a few changes and waiting on parts. The DSS aluminum driveshaft was shipped without the 'kit' which was no more than the mounting bracket for the carrier. Since Extreme Motorsports is currently closed due to a fire, I'm having to wait for DSS to open tomorrow to get it shipped. Should have been in the boxes, but it wasn't. It wasn't shipped on time, then when they hurried, I can only assume that the 'rush' to get it out caused the kit to be overlooked. Car's down now and waiting. Also making a slight change to the airbox/intake piping. The logs on the track indicate the box helping as much as .5 in the AFR. Filter bounced loose on one of the runs and the AFR's went rich. Not able to perfectly identify when it happened, but it was on one of the 2 runs we made when we were in Tulsa. Heat intakes maxed at 122 and AFR's were about 1.0 lower (richer) than I like. Currently I'm adjusting the clutch, installing the new drive shaft and working on the airbox. Hope to have it all together by shootout.

Whooo hooo! man that all looks good Tom, I am sure that this years shootout will be one to remember!
As far as that intercooler goes, I simply cannot say clearly enough how much of an improvement we get over previous coolers we have run.
On IAT sensors I will admit that we really went overkill on eliminating response time in our own custom sensors, and that this was ONLY needed to perform instantaneous compressor efficiency calculations. It was not done out of any need to improve the operation of the ECU or engine operation.
For example, when measuring the difference in charge air temps between the stock evo9 and white model turbos the differences are subtle, but easily measurable with the correct rig.
These differences may not make a 100whp change during a dyno pass, but if you are doing a 20min track session, every BTU you can eliminate from your charge air cooling system is a BTU that did not slow you down, a BTU that your FMIC did not have to absorb and inch you closer and closer to heat soak. And dont think that road course guys are the only winner here, we all road race our cars EVERYDAY
Again, kudos to you Tom, nice setup!

Robert, thanks for the post. From a garage racer view point, it's difficult to always know the difference between what we NEED and what's available, but overkill. Your idea of me using a Turbo tach was a tool that I now rely on. The first thing I check is the RPM's. Thanks to Amber and Scott for doing such a great job of helping me too. As with all things, improvements are part of the cycle. Indy and I have been working on the airbox and are upgrading the 2.5" pipe to a 3" and I got a new K&N filter to fit the 3" pipe. It has the built in horn, so we may use the 2.5" horn in another application. I also wired in a switch in the dash so I can manually turn on/off the water pump whether the engine is running or not. Heat/humidity has been pretty high, so I'm using this down time to good use. Today it will be 105 with God only knows how much humidity. Anyway, thanks for all of your support. Are you going to be at the shootout? If you come, I'll buy the beer. The whole fam damily is going to be there. Flying my daughter up to Cleveland Friday night and we'll pick her up, that way she doesn't have to miss work or starting school. We're all looking forward to the trip. Hope to see you soon.
