Re: Chevelle is about to get a big power upgrade
Definitely donít go too low on the compression, youíll just make it a slug off boost and slow to spool. I go at least 10.0-1 for my forced induction builds.... you can easily loaf around on pump gas, low boost with that compression with good timing control.
Also, no reason to spray on top of twin turbos, all you are going to do is melt ****. A 500Ē engine will have no issue spooling some properly sized turbos, and they will damn sure make enough power on their own.
All the nitrous will really do is narrow your tuning window, leave no room for error or any type of equipment failure. Now if you were trying to spool an 88mm with a 3.0l engine, then yeah spray it just to get it to spool but...in your build, youíre just asking to melt down a high dollar engine.
On the fuel, if there is anyway you can run E85, I highly recommend it. Otherwise, one tank for 93 and one for C16 is a good idea. Iíd just keep the boost really low on 93 only....or even think about a methanol injection system to help out when you are on 93 oct.
For intercooling, are you going air to water or air to air? This will affect your pump gas tune up for sure.
There is about a million factors to this build, nitrous should not be one of them.
