Turbo vs Super - Ideas & Opinions?

Agreed but we are getting way off topic.
Lets have this discusssion over in my build thread thread.

Eh, no worries here. I quite enjoy it. I always like getting opinions on this kind of stuff, and I'd rather hear it from people who have done it before. Everything helps.

How much boost were you running to make those numbers? I've always said I would be happy with 210 at the wheels, but figured 260 would be a good goal to shoot for if I was going to be building up the bottom end like I plan on doing now.

I'll be doing some work in the top end as well, new valves/springs/retainers/etc.. It's a daily driver so I don't need a whole lot of action way up high.. I do like the sound of 210wtq way down low though. If I could make that from the low end and maintain a reasonable amount of power through the curve, I'd be more than happy. Where were you making that whp at?

I believe I was running around 20-23psi. It was street tuned once again and the compression was low at 8.6:1, so it took more to get there. If I remember correctly it was 234whp and 210wtrq.

In comparison the tired stock GSR, 10:1 compression, with the same turbo setup made 297whp at 16psi.

Thought GT28's choked out in top end. But then again this is on a B1, not a C1

Those numbers seem kinda low. What dyno was this on? I've seen plenty GSR's make more power at lower psi. 16 seems a bit high to only make 297

Define choke out?

Read the thread nerd! Lol. That was on an EVO III 16g not some oversized turbo! On top of that go run on the Showzone's Mustang Dyno in Charleston, SC and I guarantee it will live up to it's heartbreaker name! Trust me I have many hours on it with a few different cars at various states being turbo'd and supercharged.

Different dynos will put out different numbers. I stuck with the same one to see the cars progression. Mr.Gurley can attest to these dynos as well since he was present.

He did say it was a tired motor so im guessing that might be it. EDIT: Of course there are heartbreaker dynos too. They arent nice to you visually.

Ironically mid range is the easiest place to make torque. But trying to make low end AND top end torque is a challenge.
Thats always been my goal.

Sounds challenging indeed. I'd love to see someone reach this goal. Dual runner intake manifolds have been used in this fashion but i think primarily achieving mid to top end. By the amount of large plenum manifolds i usually see, i'd wager this isnt optimal for turbo builds.

 

[MrGurley]

yea that dyno he's taking about is a the same settings as the buschur racing dyno and was a "heartbreaker" that shit stayed letting people down
