Name for your car??

[Thirdgen89GTA]

ASA certs simply mean you can turn a wrench and follow directions, not much else. You said 400hp? On who's estimate? You don't know what was done to the engine, you have no idea who ported the heads (if they were even ported), you don't know the cam profile, you know absolutely NOTHING about it. So how can you estimate the horsepower of that engine? Do you know the flow numbers on the heads?

There are a million questions I can ask you but you don't have a concrete answer for any of them. Most people estimate how much they think an engine will put out by comparing it to other cars with similar mods. Generally guy has "x" engine, and you built an engine using similar heads and cam profiles, with the same bolt-ons as engine "x" then you should have similar numbers. But each engine is different. Some engines have more blow-by and thus lower compression. But you don't know any of that information squirrel. So you can't estimate anything. Show me a time slip w/race weight, or a dyno sheet and then we can play juggle the numbers.

I'm not trying to insult you in the end. I'd rather educate you so you understand a bit more about how an engine makes power so you'll be less likely to spread misinformation.
