i'm puttin a forged iron 402 in my camaro but i'll be running it n/a until i get the blower on it. my question is how much will the compression ratio go up when i run the blower at 14-16lbs? originally i was going to build the engine to run 9.5 to 1 but if the blower makes it come up passed 10 to 1 i might think about 8 to 1 or 8.5 to 1 so i can keep it under 10 to 1, i really don't want to run race gas all the time. if someone could help with input that'd be great. the blower it a harrop HTV2300

 

Static compression is not effected by forced induction.

 

You might consider getting a copy of Corky Bell's book 'Supercharged!'. It will answer that question and a lot of others as you get in to the FI game. The $20 for the book could save you a bundle in your build.

awesome thanks guys! i'll check that book out and call my engine builder and discuss it with him to see what he says also

Check out all the builds on this page. We built the engines based around a 9.5/1 (or close to it) compression ratio. Going with any less compression will generally make the engine a dog down low. Bob

 

awesome thanks Bob!

 

book is 34.95 if they had it in stock i'll just call my engine builder tomorrow, he should know hopefully hahahaha

 

Check amazon, new & used copies for $16.95. Even 34.95 is cheap - if you learn the stuff you will not be at the mercy of builders, 'tuners' and carb-trained fools.

thankfully the builder has done plenty of LSX engines and the tuner is very knowledgable in LSX . . . i just haven't called them lol i see the weekend as peoples time to relax so i'll give them a call tomorrow about it. everything else i'm set on, it's just what my buddy told me yesterday kinda threw me off since i've never looked into a supercharger on my car ya know

 

$16.95, yeah i'll go ahead and order that. sucks it wont be till mid week but what can ya do
