2. and your quote on high compression is good for nitrous... you are the first person i have ever heard say that... when running high compression...

3. you need to retard timing (or high octane fuel, or combination of both) in order to not get pinging.... well with nitrous your cylinder pressures are even greater, meaning you are now retarding timing even further in order to not ping....

4. sure you can do it... but i would stay away from it

Q: Can high compression engines utilize nitrous oxide?
A: Absolutely. High or low compression ratios can work quite suitably with nitrous oxide provided the proper balance of nitrous and fuel enrichment is maintained. NOS kits are used in applications from relatively low compression stock type motors to Pro-Modifieds, which often exceed 15 to 1. Generally, the higher the compression ratio, the more ignition retard, as well as higher octane fuel, is required. For more specific information talk to one of our technicians.

5. so yeah it can work, but you will need to tune it to make it work..... and well i'm also not in the mood of needing to buy 100+ octane gas just so i can juice it


1. And that is any different than running forced induction with larger injectors & tuning the PCM how???
Also what about Venom's kits? Tried and true doing exactly what I described with a single nozzle at the TB.

Your statement is ludicrous. Think about it for just one second... You are openly bashing any dry nitrous kit or any returnless car with forced induction

2. High compression = higher Volumetric Efficiency & higher cylinder temps.
Therefore nitrous is more effective on high compression since it is more efficiently used and cools the higher cylinder temps.

I am definitely NOT the first person to ever say this.

3. You are kidding! No way. Get a grip for a second okay. No $#~! you have to tune for it. WTF - Were you thinking I would not. Heck it's just a matter of changing the timing & fuel maps. Simple to do with my TwEECer.
What do you use to tune with??? Oh that's right the engine you built broke anyway... Two can play the insulting intelligence game. It's no fun is it.

4. Then don't & Holley seems to think it's a fine idea and even states racer's run 15:1 and Nitrous (on race fuel of course - well duh!)

5. Now it can suddenly work! At the beginning of this post it was going to "definitely" blow up the engine in 3 or 4 minutes. Get your post straight...

Also you could make a program to run on any fuel octane you wanted to. (of course I'd recommend 93 or better!)
It's all in the timing and fuel control. I have 4 slots to play with and 1 bypass slot.
Even a "FLIP CHIP" has 2 programs just for this type of thing. This way you can have a normal performance program and a nitrous program at the "flip" of a switch.


I don't know if you got up on the wrong side of the bed today or just otherwise??? I definitely hope the former.
