I was told by my tuners that a 4.10 will suck-up some of your RWHP? A stock GT 4.6 is around 270 RWHP, so with the mods you should have been higher without the 4.10.
What was the stock rear on a 05 GT?

A Reduction Pulley may damage other components by not providing enough cooling.
My difference with 87 and 92 is 10 hp but that's in the new Coyote.

The rear is the 8.8". I've also been told that 4.10's lower dyno numbers but my base line was 270rwhp and by baseline I mean just the gears. I was concerned with the under drive pullies but there has never been a reported accessory problem with the Steeda pulleys so I feel confident. My car doesn't get even close to running hot so I think I'll be fine but I will also keep track of it.

Nice information. Sounds like about what I'd expect from exhaust. I need to get some LTs on mine eventually.

What CAI are you running? The FRPP has a wide pipe and a tub for the filter. No hot air in the intake, also has a moulding on top, which seals the tub with the hood. A lip over the radiator funnels cold air from the grill. Requires tuning.

I can't see top performance on a CAI with the filter having any access to the engine bay and hot air. On the previous question I asked what gear ration was your stock rear?
All GT's have been 8.8 except maybe an R. As far as ceramics I understand the coating traps heat and sends it out. No radiating into the engine bay and heating intake air.

This is the intake I have:



IAT's are at or below ambient in all of my data logging. Gets cold air from the grille and is sealed and separated from the rest of the engine bay. I ran it for a month with a canned tune but it had idle issues on that so I removed it and am waiting to get the other parts in then have it tuned for all that stuff.

Stock gears were 3.55 but the entire time I have owned the car it's had 4.10's. yeah all S197 GT's are 8.8".

I've been under a rock to long, never seen an earth reentry vehicle like that.

Lol most people have never and may never again see that intake. Expensive for an intake but beautiful nonetheless!

FWIW, I have a JLT Series II which is the short ram with a plastic partition that isn't completely sealed from the engine and when the car is moving the intake temp never goes above 10 degrees difference from outside ambient temp. So there's more cool air coming up in that driver side corner than you would think.

Not as good as a setup as what JCON has though!

Do you have an aftermarket tune on the car or are you driving it with 4.10 gears and full exhaust on the factory tune?
