Cam = 224/231 .595 LSA 114 cam

What do the numbers mean. It is supposed to be a turbo cam.

What A/R should I go with if using the 76 in rear mount form? I am going to go with the 76.

 

I like the LSA at 114, but I'd reverse that duration. I'd have to agree with Berzerker on the A/R.

 

Im running a T76/.96AR front mount on a 6.0l. It is a bit laggy for me, but Im at 7000' elevation. It spools really slow compaired to the T66/.81AR I had. If you mat it from a dig it will take 3-4 seconds to come on. On a 408 at low elevation it would be fine. If you are going to run 13-15psi I would go with the T76/.96AR. Under 12psi you might get away with a .81AR. Im afraid anything smaller will choke you up top, and bigger will be kinda laggy. Just my .02$.

 

I have bulit quite a few 408's with rear mount's . at 12lbs of boost with a T76/.96 your boarder line in the eff zone of this turbo and with out meth you'll see some high IAT's over 5300 rpm . An 88mm or a GT4202r [ thats whats on my 403 in my tbss ] will be in a very happy place on a 408 . as for spool time CAM is such a big factor . I have had very good result's with the LPE GT-7 cam it idles like stock and combined with my 3200 vig I have zero lag and have some traction issues with AWD . With a T70/.96 it made 580hp and 650 tq to all four tires on a mustang dyno at 9.5 psi . I will dyno new GT4202r this weeka nd post the results.

Just watched your video's...that's some pretty impressive stuff man!!
What else have you built?

 

My shop will be on here soon as a vendor. We have built a lot of trucks TBSS's , SRT10's, Fullsize GM's . yeh the video is at 5.5 psi total and me leaving at 1psi . I have left from a stop at 6psi but it's not very good for my tires ....LOL

 

No but it's good for entertainment and promotional vids! Lets see some 5psi AWD launches!

 

i am interested in how diferent cams would effect spool time. can you share any back to back cam swaps and how they efected hp and spool time?

 

On my 403 I have swapped between Stock ls2 cam [ 01 zo6] an 02-04 Zo6 cam , and LPE GT7 . I have done this on 4 different C-5's with rear mount's and one C6 with a rear mount what I have found is the longer the exhaust duration is the faster the turbo will spool at least 400-500 rpm sooner on my LPE gt 7 then the 02 ZO6 cam . Peak hp and Tq are 3% higher with the GT7 cam and hit sooner. This seems to work better on remote mount .

 

nice info. any comparisons on front mount cam swaps?

we did a swap from a stock 5.3 cam to an 01 z06 cam and gained 100rwhp at the same boost level. no spool time info though since we have a 5000+rpm stall. we got such killer results we had to ask ourselfs how much a 02+ cam would help or an aftermarket grind.

might have to do some serious cam swap dyno thrashing on our next project.
