very crazy, very cool. keep up the good work.
Nice work so far. Looks like it's going to be a little screamer.
Years ago I rode in a car with twin Ford 3.8 superchargers and it was amazing. Not for speed, not for power, but for the noise! Those twin chargers screamed. The owner said he had trouble picking up races because people could hear the twins making noise and just didn't want to try. Well, he didn't actually say it, he shouted it to me as we cruised down the street. It was a fun car though and at the time it was a great representation of what a DIY guy could do with efi and some used parts.
It took a bit to dig up a photo. The builder is Bob Ward. The photo is from around '99 or '00.
It's funny how you bring him up. i was searching literally for a month trying to find him. LUCKILY i got ahold of him on thirdgen and found him on asphault playground. He is informing me that i should ditch the twins and just find a single m112 or m122.
I am still going to do the m90's just due to the fact of it looks awesome...... hopefully dave can get it running flawless; if so, im going to throw the whole engine, pcm and twin supercharger setup on craigslist and try to get an ls1 out of it.
I just have no idea what i should ask for it....... yes, it will be cleaned up and painted.
I believe Bob used the 7749 and $58 from the Syclone / turbo Sunbird. It's workable code but some people have found it takes a bunch of time to get some of the transitions worked out such as switching from decel to accel. Even if the car wasn't that fast, it had a cool factor that's tough to match. I agree that a single, properly sized SC might be more fun and easier to tune.
Regardless, you're going to have a cool car when done.
You might also want to check out a turbocharged TBI Cavalier that used to be on v6z24.org. Username was 1redry. Car was built (IIRC) without an ecm that was boost specific. IIRC he made decent HP numbers for a mild car.
Yeah, i have no clue about the computer stuff. I can wire it all up but when it comes to tuning, i'm at a loss, hence why Dave is in the picture.
I am running a 16196395 PCM that was previously tuned by eagle mark. Unfortunately, he can't guide me anymore. I don't see how a single supercharger will be any different than twins..... turbo's most definately, but superchargers are belt driven so a projected RPM will be the same every single time [single or twins] rather than a turbo which will fluctuate.
I sure hope so! :D
I'll see if i can get ahold of him. Thanks for the info.
With you saying without an ecm which was boost specific, do you mean that he just has a timing box, and a 2:1 FPR controlling it?
