Thanks, I'm glad it started such a good tuning discussion too :thumb:
I see where you're coming from with that in relation to RPM. I know where Paul placed most people's timing curves and how they typical 8V car reacted to them, and also comparitevly (spelling?) how my car acted with each degree in comparison.
With the right combination of parts and cyl. head, the 8V cars act very similar to a 16V setup as far as power per psi, timing, etc.
I was seriously throwing that SRT4 stuff out there as a question really. I don't know why they have so much timing in them stock. The turbo was also the only thing that I could come up with as being deviant from other typical cars. :p Man they're small! You should see one off of a car if you haven't... crazy!
I had an SRT-4 for a while and you're right, that damn turbo was tiny! I couldn't believe it when I was looking at the car, but it sure did scoot along pretty well. Mine went 13.40 @ 100.7 bone stock, right down to the paper air filter on an easy (don't break anything!!!) 1.95ish slick launch.
Yeah, have you seen them out of the engine? Interesting for sure. We had my roomates out of his car, since it randomly fragged the crank trigger and destroyed just about everything in the bottom end. 'Tis a shame.
The new Honda K series engine has a strange piston design as well. Perhaps it's a new move in the automotive world. I couldn't understand why they put a wedgish dome on the piston, but with them so low in the hole I guess I understand it. Weird for sure though. There has to be a reason.
From the Hot Rod article
http://hotrod.com/techarticles/engin.../pictures.html
"CFD analysis and dyno testing showed that the ski-jump-shaped dome on the piston was desirable for performance, so compression ratio was reduced to 8.1:1 by decreasing the piston compression height to lower piston position in the cylinder"

That car is sweeeeet. Those drag radial wheels look the best on it. I love the outside gauges too, you never see that any more... what are they for?
Thanks! Hood gauges are fuel pressure and oil pressure, two things I'd rather not plumb into the car, and I prefer mechanical gauges over electric ones :thumb:
It runs... and now drives. I drove it around the block... not once, but twice, and clicked off the first mile on the odometer since Topeka in '06. Time to try to tidy the mess up a bit and get it presentable for SDAC!
That is all.
Sweet! If it went around the block and nothing fell off of it, I'd say it's ready for racing!
Whats the general rule for breaking in an aluminum rod motor or new ACT clutch? 1 mile ok? :D
Nice work, JT! Congrats! I think the correct breaking method for both is a staging burnout on a water "puddle"...
I can hardly wait to see it back from the "ashes" this weekend!
Hopefully the "puddle" won't be provided by the car!!:p
I can't believe you haven't had that beast at the Grove yet for some shakedowns!! In private at your proving grounds?? Mebby:o
(I finally found a flowbench that's accessible.. How well do you know the guys at Bosch in Broadview?)
Third year in a row and no SDAC.. I'll make up for it at Belvedere! :thumb:
Thanks guys, its only a year late too! And no more puddles, finally! :thumb:
Sorry you can't make it Sean, we'll definitely be partying in Belvidere :thumb:
Here is a spy photo from the BadAssPerformance proving grounds last Sunday :eyebrows: Too bad I didn't get a chance for any tuning...

Damn that truck looks purdy pullin that thing around!:thumb:
I'll run a quick plan for Belvedere through the list(provided we can take over the same hotel..).. Y'all ain't getting rid of me that easy:p I'll do an SDAC sooner or later. Maybe in a nice 88 Daytona or Dave's Omni;)
Congrats JT and have fun...man that truck looks sharp with those rims, nice stance!
