See sig. This was at 3250lbs on ~10lbs A/A IC, 1.32 hot side shifting at 7K. It was lean too cause I ran out of injector(50lbs). I plan on trying E85 this year and see what it does on the same boost level.

Bullseye S480R (1.32 rear) we made 964hp & 810ft @ crank 355ci iron headed holden engine @ only 18psi @ only 6500rpm it would make a lot more but a stock block aint going to take that also non intercooled just watermeth kit kicking in at 7psi
Very impressive!! cast iron, carby, non intercooled.
I just built a S475 383 LS1 with no cooler just an AIS kit with 3 nozzles and I am struggling to find a tuner in QLD that has any clue!

I'm in Mackay ott308 and i've had the same trouble with my S480 SBC combo. I'm going to be ordering a bigstuff 3 ecu off pistolpete soon. Pretty bad when you have to deal with someone on the otherside of the country.

Very frustrating PRO386. Have you tried talking to Lionel Durrie? I think he is in Rockhampton? I am on the Sunshine Coast and have seriously considered doing courses and tuning myself or taking a week of work and trailer it to someone like Jake Edwards.

Fuck dude, that is exactly what i thought when i decided to start this project. I got rid of my old twin turbo 308 with Wolf ecu as no one wanted to touch it. That cost me alot of money and different tuners to sort out. I think the main problem with my setup is I am not running a intercooler just a AIS progressive kit with 3 nozzles. And the tuners i speak to (ranging from Goldie to Sunshine Coast) have never tuned with meth injection before and insist i run an intercooler. It is a 99% street car (1961 chevy belair) and don't want shit out the front of my car. At the moment I am seeing 450rwhp (mainline dyno) at 15psi with a S475 T4 frame turbo (9 inch, powerglide) converter did show 37% slip.(just ordered a PTC converter)

Anyone with first hand s480 experience, do you think this might be a good choice for 387 cubes (4" bore, 3.79" stroke), street driven vehicle at ~4000 pounds, 3.55 gears, spinning up to 6200rpm or so, for about 15psi (or less) for most operation? I was thinking the 80mm compressor with a t4 hot side, 92ldp turbine wheel. Probably a 1.25 housing? I'm kinda stuck with a t4 instead of a t6, but even if I could change to a t6 I couldn't fit a 5" down pipe. It looks like there's a few people here with 350-400 cubes using s480's that probably have some great input, although they're probably mostly used for drag racing and weigh less, etc. Thoughts, opinions? Thanks.

I know of Lionel but with him still being few hours away its just as easy to deal with Pistol Pete In Melbourne who regularly uses the stuff I need.

Race cover is ~.5" larger diameter. As for hotside, the T6 1.10 is virtually a drop in to a 1.32. You may have to shift the downpipe a hair, but nothing substantial.
what about fitment with 1.00 or 1.20 housings? I think they may not be interchangeable with the 1.32 housing something about the center section, but exterior fitment wise?
