[QUOTE=SwampWS6;20022106]Anymore details on this build?[/QUOT
Yea it's going in a 1976 c10 it's a leaf spring small tire truck for no prep. Dont plan on setting the world on fire, but hopefully it does ok. I wish I had the dyno sheet, but my friend doesn't want numbers out there from a dyno sheet. I know it did almost 1900 torque

damn 1746 is a good ass number but I made the same lbs of boost with a s480 I’m sure a lsx will push more air with that turbo. Is that with the 100mm turbine wheel ?

Yes 100mm billet wheel done by Jose

Anybody ever do any business with the company crt turbos or Midwest turbo. They build some of there own turbos out a garret turbos and I read some pretty good stuff on them and they have a decent price. They come with the g trim exhaust wheel too. http://stores.customracingturbos.com/lft106-billet/

It hasn't yet. It's going in a leaf spring 76 c10. Hoping it can run decent in small tire no prep stuff

I seen where jose and Bewley shared it a few times. I was just curious if it had ran yet.

Unfortunately we live in Nebraska so the tracks are closed and it had some issues on the dyno that the builder is fixing. Probably won't get any runs til April or May

88 would be X275 legal, but I have a few friends running 94s and even 98s

I just wanted to reply to this as my buddies sbc ended up making 1931hp on 28 pounds of boost on the s491 with 100mm wheel. Had to shut it down as it over heated the dyno

I would think it would be a pretty big pickup if you did a s488 or s491 with the 100mm exhaust wheel over the cast s480. The nice part is that it will just bolt right up

Do you mind sharing CI, rpm and back pressure?

427 18 degree brodix heads 16 injectors that pull went to 7000 and the dyno over heated. Not sure on the back pressure, said it could maybe make a little more. He's eventually going to go bigger.

dayum ! Those are good numbers. Yea I’m really interested to see what this puts out on the dyno. At thise point I wish I would have went with the 91/100. The way the turbo is hung on the front of the car had to do a bunch of cutting and changing. Like the outlet on the pt106 is 4”! And my intercooler pipe is 3”. Also the bar that supports the t6 flange had to be cut and welded at a different angle because of the crazy size of the turbo hotside. So hopefully it will be all worth it in the end and I’ll hit my 4.xx goal. I’m setttjng it high and not saying 4.50s 🤷🏼dum♂️ We will see

I thought i posted this in this forum? I ended up going with a precision billet 106mm I got brand new that someone used for mock-up 😁 thing is a monster compared to my 80mm. This should make it got 4.xx’s for sure

I’m also building a street car identical to the race car but a factory ss with a Huron speed t6 kit. That is coming along nice and slow. Hopefully done by spring to play in the streets around here. Old borg Warner turbo is on this car now, and a stock bottom end gen 4 5.3 with lil John motorsports cam and all the good stuff on the top end from Brian tooley. Also has head studs hopefully will make 800hp without falling apart.

Its a 5” core from Huron speed all I know. I can get some measurements if you need them. Came with the Huron speed t6 kit I bought used

47ford 03-05-2019 05:14 PM

No it’s ok I was just curious.... I bought the eBay 4 inch core from cx racing and was just wondering what the results will be on E85....
