Guest drizzle Posted August 9, 2007 Share Posted August 9, 2007 have you looked into the 32valve Arao heads supposed 350cfm with good lower rpm power. http://www.araoengineering.com/ Quote Link to comment Share on other sites More sharing options...

Kevin Shasteen Posted August 19, 2007 Share Posted August 19, 2007 This is simply not true. While static compression certainly has an effect on efficiency, it's fuel and timing that will determine how efficient the combination will ultimately be- and how long the motor will take the abuse. 13:1 engines work great with nitrous oxide, and you can guarantee that the 13:1 engine will outperform the 8.0:1 engine, and by a huge margin- provided the tune is good. Even supercharged motors can operate in the 11:1 range very effectively- and there are many that do this in lieu of the old school thought of low compression with boost. Compression is a small factor in comparison to fuel and timing. The new stand alone engine management systems such as the F.A.S.T. system have made compression a non-factor, or at least minimal as compared to the fuel/timing curve..... Did I miss something? My comments were relative to his only wanting an addt'l 100 hp and that he would be running with mufflers. He didnt come right out and say he wanted a streetable car but only wanting an addt'l 100 hp indicates he's wanting to run on pump gas and keep the car streetable. You can not run an 13:1 streetable car with a supercharger or turbocharger on pump gas w/out serious and immedieate longevity issues. Sure you could reach extremes but at the loss of streetability. Yes you can run an 11:1 SCR engine (Normally Aspirated) as long as the tune is correct...as you said many modern mfg's are doing this now and have been for awhile. An 11:1 on up SCR with a power adder is Pro Racing territory. From my reading his initial inquirey - he isn't wanting to reach those heights. My comments about his addt'l desired 100 hp was correct in that whichever decision he made, be it normally aspirated or power adder, he needs to tune accordingly.

Guest Gr8White Posted August 20, 2007 Share Posted August 20, 2007 You can not run an 13:1 streetable car with a supercharger or turbocharger on pump gas w/out serious and immedieate longevity issues. Kevin, (Yea,Still an Inliner) Hi Kevin, I guess I could have been more specific, the only thing that I really diagreed on was your original statement of not being able to run a nitrous car effectively @ 13:1, with my contention being that nitrous oxide works very well at 13:1. You grouped nitrous and supercharging together, 2 totally different animals, wouldn't you agree? I've yet to see a streetable 13:1 car, naturally aspirated or otherwise!

Kevin Shasteen Posted August 23, 2007 Share Posted August 23, 2007 Yea, I guess I could've been a little more specific also....I hate it when that happens. Kevin, (Yea,Still an Inliner) Quote Link to comment Share on other sites More sharing options...
a6t8vw Posted September 5, 2007 Share Posted September 5, 2007 just do a stock rebuild and one new borg warner S400 ($600) turbo and you'll make 500hp on accident Quote Link to comment Share on other sites More sharing options...
lilredZ Posted September 9, 2007 Author Share Posted September 9, 2007 hey did you say you had video of my car? can you forward it to me? rustyosgood@yahoo.com thanks Quote Link to comment Share on other sites More sharing options...
lilredZ Posted September 9, 2007 Author Share Posted September 9, 2007 doesn't look like these will fit my engine...but they do look good...almost worth changing engines for...! Quote Link to comment Share on other sites More sharing options...
