Stormer's 73 Imperial Build

Nope you probably can't even see the turbos. You can safely add two or 300 hp on the stock bottom end with the right tune. It's all in the tune.

It's all in the tune. Add fuel & remove timing & keep your IAT's as low as possible ( intercooler + methanol).


The correct answer has to be two hp, because adding 300 hp with stock pistons will make for a short lived engine. I can see why you don't build your own engines, because adding fuel and backing off timing to reduce detonation has a minimal affect, like putting a band-aid on a broken leg. A lower compression ratio is neccesary for an engine that will be supercharged by a turbo, or a blower running any desirable amount of boost... Not to mention good forged pistons. Even low expansion forged pistons (4032 alloy) that are common these days will not hold up to adding 300hp, especially with too high of an effective compression ratio.

It most certainly is not all in the tune. You can't make chicken salad from chicken ****. Backing off timing kills power in a big way, you need to research how much boost you are planning, and build your engine around your cam profile to determine what static compression to run. I'm sure it is common for sales people to rave about selling expensive bolt on turbos etc. and yes it may run like hell.... For a limited time. People have done the same thing with nitrous for years, and will continue to do so, with no regard to piston material, piston clearance, or ring gap... or the crank and rods depending on how far they are reaching...

Also, isn't methanol and injectors a bad mix? I would be checking your operator's manual. From my experience ethanol would not be an issue, but methanol would damage injectors.
 
Huh? WTF were you doing on a low rider forum?

Arrived there quite by accident, web surfing and all that. My immediate gut reaction was a viseral discust but then I began to admire the guys dedication to his car. I maynot like what he is doing to it, no---I absolutely hate what he's doing to it BUT it is much better (yea I'll admit it)to the other two notorious alternatives.
 
has2bmopar: well, you're right that 300 is really pushing it but you're wrong about pretty much everything else. You're obviously a smart guy & you surely know a ton more about cars than I do. You're also correct that using low compression forged internals is the way to go for big boost. But.... There are tons of guys who have run 6 or 8pounds of boost on a stock bottom end for hundreds of thousands of miles. Adding fuel & removing timing is exactly how you control detonation. It is in the tune, period. I'm not a methanol fan because if it fails you go pop. I told my buddy it's a bad idea & he should just run less boost.
 
Well, when your foreman scatters engine parts over three counties and then brags that it was because "that thing had so much horsepower that it...", I'll know the truth.
He'll even use blowing it up as bragging rights. I have seen his type over and over and....
 
300 boosted hp on cast pistons will result in disaster. On the other hand...I've seen plenty of people that thought they knew how to "tune" a single stage of nitrous and destroy the engine quickly.

OK, I've already said that 300 is really pushing it, you guys are killing me. You're absolutely right about the nitrous, it can be very dangerous. If you just slap some nitrous on a stock car with no tuning you're playing with fire. I have 2 WOT safety switches & 2 fuel pressure safety switches so it is impossible for me to spray at anything but WOT with both fuel pumps pumping. I'm also measuring AFR which most guys who go pop probably aren't. 6.1's have a forged crank by the way & they can take a beating as long as you don't run out of fuel & you back off some timing. LOTS of guys running 6-8 pounds on completely stock 6.1 daily drivers. LOTS

Who gives a rats *** about a vette.
My buddy loves his. But hopefully you'll like this better. I'll try to attach the first video of my Challenger running with the new, yes, all forged 426. 10.5:1 compression so it should run pretty good N/A but built to take a big shot.

Dammit, I can't figure out how to do it. Hold please....
