"We're currently at the 800-hp level after starting with about 140 hp with the production engine as installed in a production car," said O'Blenes. "We were able to make between 370 and 400 hp with billet rods and forged pistons with everything else stock." The production engine underwent various alterations, including the aluminum block (modified with stainless steel O-rings and copper head gaskets to withstand cylinder pressure resulting from the turbocharger); cylinder heads (ported and outfitted with dual-coil valve springs and titanium retainers—support was added for the numbers 1 and 4 combustion chamber); camshaft drive gears (slotted to allow adjustments in camshaft phasing); and camshaft drive (stock timing chain, guides, and hydraulic tensioner). "We were able to start with a really good base engine package," said O'Blenes. In addition to retaining stock components whenever possible, goals of the racing engine program centered on producing more than 447 kW (600 hp) for the Sunfire application (which uses no intercooler) and more than 522 kW (700 hp) for the Cavalier application (which allows an intercooler). The desired power band was targeted from 5500 to 9200 rpm. GM Racing also wanted the durability to make 25 full power sprints between engine rebuilds. The program exceeded on all counts. Early in the race season, the power band was ranging between 5500 and 9700 rpm, while engine durability was allowing between 35 and 55 full passes between rebuilds. To reach over 578 kW (775 hp), three primary aspects were key to the power supply. "The heart of it is in the cylinder heads—machining the ports to increase the airflow; the camshaft profiles—more lift and more duration; and the turbo," said O'Blenes If you count the engine block casting, and head casting as half the build, then its 50%? The car runs on alcohol...that is just insane.

uhh.... hi.

Welcome Mike!

nice car ( and power adder )

Hopefully I'll be there.... ..fully clothed.

happy late birthday!, you homo redface.gif

60 roll. Naked. I'll have my bottle filled.

I think it would be cool. smile.gif

thats what I was just about to add

Clay, First - Thank you for coming out last night to campus and helping out. Your meal is still on me next time out. Second - Is there anyway to unplug the vacumn signal to the Opti? Pinging is usually the effect of to lean fueling, and/or to advanced timing. If unpluging it kills the ping, then there is to much advance under vacumn Usually if the Opti fails completely, it leaves the car on the side of the road, and won't start. It would be pretty obvious if spark timing was off in brisk accelerations, also. HTH, Nathan

I figured..I don't know if the srt-4 motor is a derived child to the fathering DSM motors, but I'd wadger so. It seems dodge was all about the 2 valve's and then when they got together with Mitsu, Mitsu was like...fuck that noise. I'd also rock a Mopar...they put a turbo motor in a mini-van...how bad ass is that?

you tongue.gif

Look up mopar's history with turbocharging. They are the results of years of field application. Omnis, Colts, Galant Vr4, Shadow, Duster... None were in the Fast & Furious.

graemlins/thatfunny.gif Take the Dodge for what it is...Mopar is in the game again with something that is competitively priced, well engineered, and isn't to bad looking. All I have to say is if a company can produce a motor, stand behind it while they give it hell, it is a company I wouldn't mind buying a car from. Sure, it may take a stage 2 on 100 octane to combat a stock 03 or a stock c5, even with the mods, the neon is still significantly cheaper. Yes, the neon will always be a neon Deal with it...

smile.gif yay

scotty doesn't know so don't tell scotty. Cheer up holms, it could be worse...atleast she wasn't like..a man or something...

haha, that is terrible.

Ah, I'm down here at metro, is it true that you guys are wired 10 base??

for what its worth, WinFS will be interesting, to say the least. All x86 architecture is backwards compatiable, and all true 64bit systems are not being used unless the OS has the extended registries for the 64bit platform. Looks like XP, can't wait for the first service pack...

what floor are you guys on?!?

you fear the kia.
