The turbos on the ZR1 are twin 76mm, making them the largest turbos ever fitted to a production car. So, big enough right lol? OEM’s are famous for under sizing turbos. I have twins on my Expediton Limited (3.5L EcoBoost) and I like to joke the turbos are the size of silver dollars. That...

The control arms you specifically called out. Thanks.

If you think pushing a smaller turbo harder and outside its efficiency island doesn’t increase temps, then there isn’t much for us to talk about lol The Ecoboost is DI just like the ZR1 and has a lower CR than a Coyote since it was designed for boost. So I’m not sure where you’re going with...

Good info. Are they a direct swap into a 550?

10-4 Just throwing out that option in case it helps. 👍

Just to be clear, this is not true. A bigger turbo will have much lower IATs than a small turbo that is pushed hard. Perfect example is the new ZR1. Massive turbos allowed GM to make 1064 HP on 93 octane fuel since the charge temperature is so low.

Buy a drum and have it shipped to your house. Run 93 for routine driving and run E85 when you need the power and cooling. Just a suggestion. It’ll really depend where you’re trying to get to power wise.

Depends what the OP’s power goal is. If he wants more power, that means more airflow and a turbo matched to the increase airflow and pressure ratio makes much more sense than pushing the OEM turbo to a spot on its compressor map where it’s not effective. E85 is a godsend for any boosted engine...

I think the better question is, who makes a better turbo for the EB? And what octane fuel can the OP run (E85 or is it just crappy pump gas)? When you push the small OEM turbo outside of its efficiency island (generating much more heat) and couple that with low grade fuel that cannot handle...

You would make the same power if your IAT2 was 30-40 degrees higher since you’re on E. FYI my Camaro makes 1066 WHP on 140 degree IAT2 at virtually the same boost level you have. If you have the right fuel IAT is a relative non issue. Look at all the no prep guys making huge power…most don’t...

100% spot on, @engineermike

E85 really doesn’t give a crap what your IAT2 is (within reason, of course). 110, 120, 130 degrees, etc is a non factor since E will cool the combustion charge and even if it didn’t, the octane number is so good you’re not going to knock. You’ll still make great power even on “high” IAT2...

100%! My son is in his early 20’s and we’ve let him drive the Mustang and my AMG a couple of times (both around 500 HP) and he loves them. But I know he’s not ready for my 1200+ HP Camaro. At some point that will happen though and I’ll be turning down the boost controller without telling him. 😂

Same here

Hey we don’t want it either WTF 😂

Sorry to hear. Best of luck with your wife’s situation.

That article blew that way out of proportion… sheesh. No one is getting tased over a license plate from lol

Any professional hvac supply house will have a composite pad that will be fine. They’re usually 2” or 3” thick and will easily handle the condenser weight.

I literally just did the Active Exhaust Upgrade Kit on our ‘22 GT, and my experience is identical to yours @Mustang Maverick I feel like the tips are too far down and not well centered in the new valence. They provided new hangers for the intermediate part of the exhaust but I really feel...

FYI our company owner asked me to negotiate a new ZR1 for him, and he could have bought a ZR1 with the ADM less than a third of what you posted. Not saying that there aren’t some people paying that… but the average was $50K-$80K ADM depending on color and options. I had one dealer offering to...
