Ah, that's why they go so well, race suspension!!!

The TT looks awesome, rear sway bars help a lot in those too.

I can't wait to drive it back up here. The reliability is what I love, apparently it's tuned so I can't do any damage to it!!!

Then new radiator will be the same general shape as the one I have now, I still don't want to cut into the body under the hood, but thank you for the offer. I might have one made that is wider than the one I have now, but the same height.

Picked her up last night, of course it was the first time in weeks that it rained, so that sucked.

Scary is the world I'd use for it. Not just the power, but the rear suspension too. There is a LOT of torque, I was in second, hit the gas and I was spinning, back end sliding sideways. It was wet, but but I can't even do that in my M3! So tons of torque and power. The engine is sitting right behind me, so even with earplugs in, that turbo was really working. I was going over 100 easily, but it cruised really nicely at 85. At the faster speeds it was scary, the rear suspension is REALLY not working well. I'm going to look at putting some spacers under the steering rack back there to maybe give me some toe in bump over what I'm sure is toe-out bump right now. That's what is scary, you hit a bump in a corner and the whole rear end feels like it shifts sideways. The redline is 7200 rpm, and I didn't even get close to that at 100, so I don't know how fact it goes on the top end. Javad the tuner said he noticed some clutch slippage, but I have to say all I notice was wheel slippage.

The shifter works great, until it doesn't work well. I can't explain it, but it shifts great most of the time, then rarely its a struggle to get in gear. Don't know what's going on with that.

Temp was a steady 85 degrees, even with just the 2 fans running. They had set the thermostat for 80, so first the first leg of my trip the fans came on and stayed on, kinda worried me. The ECU was in demo mode too, and I didn't realize it, so I couldn't figure out why the temps were running 95 and the RPMs were staying constant!!!

I'm going to lay low for awhile now, between the 3 hours of tuning, 1 hour of testing and cleanup, and new coils and firmware for the ECU, it was over $1k, so I need to fill my piggybank up again!

Exelent to hear your car it's running, I hope you can solve the rear suspension problem.

Do you try with Suspension Analizer software? you have 10 day's trial and for my car it's very helpful. You can calculate the position and length of the arms for best numbers for toe in.

Hi Hugo! Glad to see you are making progress on your ride too!

I think that program might be very helpful, I just don't trust my ability to see the big picture. While that program might tell you it will work, I think more knowledge will give me better results. I should probably trust myself more on these things, but I have very high goals for the way my car will handle when I'm done, and I want to do everything I can to make sure the road from here to there is as short and as straight as possible. I just wish the toll wasn't so expensive!!!

Keep us updated on your progress!

A friend and I had a little fun last night. He has an '07 Suby STi with total intake and exhaust mods and chip retuning. We did some drag racing, rolling starts, and freeway speed runs. Surprisingly, we were neck and neck! He slowed after we pass 90mph, where I'm sure he would be faster, but in everything else he could not leave me. I left him quickly at 90 and I'm guessing I hit at least 110. The whole reason we got on the freeway is to see how fast I was, but he doesn't like breakin' the law! What surprised me the most was breaking the tires loose after shifting into second. I didnt drop the clutch, already in second, and just the power broke the tires loose! Just goes to show what light weight and power can do...

Power goooood!

Corruption on the way!

Took a trip over to Huffaker Engineering at Infineon yesterday. Joe Jr. is an amazing guy, I'm looking forward to working with him. He didn't have time to get into specifics, just put the car on the lift and scratched his head a bit and agreed with my diagnosis of off-kilter rear geometry and he agreed that the sensation I feel is probably bump toe-out. To keep me busy he helped me diagnose my brake bias issues, so I've ordered a 1-1/8 in MC to replace the 7/8 rear MC so I decrease the rear brake bias and also increase pedal travel. I'm going to take a picture of the 944T torsion beam cover and send it to him, it may play a usefull roll in the rear suspension redu, but I may end up with a full double-wishbone rear suspension! Motor is still running strong, but I think I hear a little detonation in 5th under full throttle, so I'm not too happy about that, and cold running is still an issue. Some ECU adjustments should take care of those issues.

On my trip I had an "event". The frame horn sits about 2" off the ground, too low, but thats where the springs settled to. It's fine with me in it, but my wife wanted to go too, so it was a little lower. We took the scenic route, big mistake. The road was rough and annoying, but the rear problem developed when I find myself staring down a dead possum in the middle of the road. I don't mean fresh dead either, but not squished low enough to fit under the car... Bam, then the smell of rotting flesh, nasty. The smell subsided replaced with the sweet smell of antifreeze.... After surviving the first hit, the radiator couldn't handle this hit and started to leak. Fortunately I can look in the back seat and see the coolant expansion tank, and I could watch it slowly drain. Got to a gas station, filled it up, and was able to get back home. By the time I arrived, it had somehow stopped leaking, and is still sealed!!! I think the orange antifreeze I have must have some sealing properties...

Still no dyno sheet...
