I'm on the largest pulley, no problem so far with 633whp

Wish it was easy and cost effective swapping to gt500 cats

From what I read, the stock cats hold higher temps than any aftermarket cat. Thats one of the reasons I'm staying on low boost. Apparently, its either oem cats or no cats at all.

True, I figured that the hard way 😅

Its actually not that far. I see 6.5psi(on the 6.5psi pulley)at aprox 7100rpm. Ofcourse the more you rev it the higher the boost goes. At rev limiter I'm at 8psi

Wengerd Performance had no issue tuning mine with lu52 injectors and bap. Made 633whp on largest pulley(lowest boost) and stock cats. I'm very happy with it

I believe its due to the high step up ratio of 4.5:1 compared to procharger's 4.1:1.

Its tight, I'd say around 60-70%, not sure though...was definitely impossible for me to get the recommended size even with a breaker bar on the tensioner and sliding on the smooth idler last🤷🏻‍♂️

I tried but couldnt do it with that one and used K061037 at the end. Here's how my tensioner looks with the 37. Think its good🤷🏻‍♂️

Straight up What belt did you use?

Best advice 👌

Agree, I went with Bilstein cuz frpp were out of stock at the time. Saves you some money and time.

I bought them from this vendor a year ago: https://www.ebay.com/itm/Bilstein-B6-for-15-17-Ford-for-Mustang-GT-V6-Front-Monotube-Strut-Assembly-bil-/123723002846?mkcid=16&mkevt=1&_trksid=p2349624.m46890.l49286&mkrid=711-127632-2357-0...

M-18000-F are very similar to B6 and come with new shock mounts

Run a compression test before installing the SC if you want to be sure your engine is healthy. The whipple tune is one of the safest but many variables come into play when increasing cylinder pressure on a 12:1 CR engine. Detonation is your enemy so only run the best fuel you have in your area...

There's a few other threads and some good info about it on this forum. When dealing with increasing cylinder pressure over oem specs things can go wrong and with a 12:1 compression ratio you're very limited on pump gas. But many other variables are involved. Check this thread for some...

Supercharged for 633whp on 7psi

Feels like stock till about 2500-3000, after 3k it starts building boost and pulls harder than stock. Keeps building power as you go up and goes into beast mode above 5k.

633 whp in 7th gear on 6.5 pulley, stock cats and manifold. Only other performance mod is x pipe. Very, very happy. Not bad for the smallest G2 unit on the largest pulley. Unfortunately they had an issue with the rpm reader so couldnt see tq and took the reading by mph only.

For comparison here's a video of whats supposed to be helical. Honestly I dont hear much difference unless Brevin mixed up units and sent me a straight cut instead of helical gears 🤷
