Everyone was wrong then. For a close to stock truck, the 60mm upgrade is alright. However, once you add bigger injectors, or turn the pump up on a Non I/C truck, it's pretty much useless. Richie O is making right around 300rwhp with his '89, with an S300G (much better than an H1C) and still has EGT problems.

If you want 450rwhp, a 62/71/14 S300 is the turbo you should be looking at, not an H1C.

 

I'm gonna go ahead and reply to this one. He's 16 and doing mild mods for now.

 

What does age have to do with anything? I was replying to what I put in bold. No matter how old you are, or if you're only doing mild mods, a 60mm H1C will still not support 450rwhp. Spreading information doesn't do any good if you spread the wrong information. I was simply correcting him, and I know I'd want someone to do the same to me if I thought something that turned out to be wrong. I wasn't trying to be a jerk, if it came off that way, but I didn't want him spreading false information either.

 

Sorry, I wasn't implying that you were rude, I didn't notice the bold letters. I took it as you were just explaining to him that he needed a bigger turbo. I was missing the big picture. And good call, That turbo would have a heck of a time making that hp if it can be done at all, and if you put one on a 450 hp truck it would probably end up in a bunch of small pieces in a hury.

 

sorry guys for saying tht maybe it was 350 hp cause 450 hp is proly to much for tht thing to handle i was wrong but im still learnin

 

well the upgrade woks better on my truck then the stock turbo set up. and i'm prolly only pushen 250ish hp. but 1400* is better then wrapen around past 1600* on the pryo so its a good investment till tax return time.
