Wow, your car looks terrifying. Excellent craftsmanship. I was just wondering what you did with your track bar to clear the duals, I couldn't see in the pictures. Any plans on showing the car at any particular events this summer, it would be awesome to see it in person.
not wanting to hijack hi thread here guys but will answer really quick. I made 450rwhp have the sheets for it n/a with a 383 in my 94 z-28 with 30 lbs injectors. Running more base pressure on it of course but not a bunch more than stock. I dont know what my car makes now but at over 3400 lbs and running yes 10s at over 135 on 6 lbs I am guessing I am over 600 rwhp. my car that made 450 rwhp was lightened and weighed 3250 and ran 10.9 @ 126 on a 100 shot it ran 12 mph faster. That is why I wanted to know his combo for the engine to compare to mine. My car before the turbo with more compression was making almost 400 rwhp ran 118 in the quarter. I added the afr eliminator heads that are race ported and the turbo thats it. Lowered the compression to 9.5 from 11.5. I good flowing set of heads(these are over 300 cfm) will make a bunch of power on low boost. I know of a mustang that runs a 380 inch yates based head(nascar stuff) 88mm turbo and on 5 lbs ran 128 in the eighth and couldnt get it through the quarter was on drag radials and kept destroying the tires in 4th gear and getting out of shape. He said it got boost creep to 7 lbs in 4th gear and that would make it kill the tires and always had to back out of it. So I know that you can make big power on lower boost if you have a good flowing engine. I was hoping for 128 out of my car on 5 lbs and 140 on 10 lbs and have exceeded my goals. I dont have anyone around here to really compare it to as all the turbo cars are mustangs and most are very light 2800 lbs so searching for comparisons to mine. By the way I am very close to maxing out these injectors at factory pressure and why I cant up the boost to 10. I run the code $59 and have my ve at 96% and boost table X77 near max and still lean at 10 lbs. Going to up the pressure and retune unless I can find some 60s cheap or someone up for a trade. I have a really good injector lucas 42 lbs that ran 600 bucks about 10 years ago. Probably 200 now.lol with the way injectors have come down.

Hey guys, wow its been almost are year since ive poked my head in over here, sorry havent been around to answer questions and for updates. The car was put on the back burner this year, life and other projects set me back abit.
Last time i had the car out for abit more street tuning, a bump over a set of train tracks took the the intercooler scoop out which messed the rad up. The car has just been sitting untill i can find the time to fix that and a few other things that are keeeping me from completing the project. So still no track times or new dyno numbers but stay tuned.
