Hey Shantin if you go to EPP's web site and go to the project cars, just click on Scott's camaro, you can see pictures of the oil return going to oil pan. I am wanting to get this thing to a track also, i will have to go down south to find a decent track this time of year.

A T76 is would work better on your setup if you got rid of the SLPs, the 67 is too small. I've seen them snap the shaft at 13psi, spit the exhaust wheel right out the exhaust. When I went from my 67 to my 76 I had zero increase in lag.
Might want to check the back pressure as well. Mine is 45psi at 15psi of boost over 5500 rpms. I'm switching out to a .96 a/r housing and insulating the rest of my exhaust. Should have it up and running next week.
Where those dyno number locked or unlocked and what is the converter rated at and what does it flash to under boost?
My setup made 520 SAE but only 470 Uncorrected on a mustang dyno @ 14psi and I'm going mid 10's. My numbers and your numbers are very different, but it could be due to me being th400.

I was not able to get more than 13-14psi out of the SLP setup even with holding the waste gate shut.

My brother's '95 Formula with it's 4000 stall Neal Chance converter and turbo 400 only shows 367 rwhp on my Mustang dyno, yet it runs 11.32 at 118 mph.
This Camaro SS with the STS has the 4L60E with a locked converter.
Scott will have to tell you what his Vigilante converter flashes to, I'm not sure. Bob

Hey Zombie you could be very well correct about my LT's. But when the hammer goes down, the power is there quicker than a lot-lizard (truckstop prostitute) looking for more rock. Not even the hint of any lag at all. The massive hit of torque is overwhelming! Bob and Brent and Chip did a hell of of a job getting things correct from the set up from STS. It seems almost everyone says that the GT-67 isn't good for anything over 600ish HP. Their mustang dyno says otherwise. I spend a lot of time reading here on LS1tech, and there is so much factually incorrect information on here. True I could switch out that 67 for a 76 and would make more power, this i have no doubt what so ever. With the numbers my car put down on a mustang dyno, i would bet that @ low boost(6.8lbs) she will be easily in the 10's, 9's on high boost if she hooks. I hope ya had a good Thanksgiving!

Scott(382-$T$), not to be a buzz kill, but the graph you posted does show that it takes quite a bit of time to reach full boost when locked(equivelent to a manual car). 5000 rpms is pretty slow for a 67 turbo to reach peak boost. When you drive it on the street and it's unlocked the converter masks most of this which is a good thing.
I'm not saying to change your setup, I'm just letting you know that there is more available if you want to change it in the future (which you probably will). I hated my SLP headers and they hated speed bumps even worse. Experimentation that my friend and I have done has shown that Jet Hot coating seems to work the best. No idea why it works so much better though. We have tried several combos with long tubes and the jet hot hookers have been the best heat retention wise by a large amount. My SLPs flat out sucked, had to go to a .70 a/r housing to get it to spool like your car does now.
BTW, where is your converter flashing to under boost, where does it stall too on the foot brake before building boost and how fast/much does it spool on the foot brake? What is the converter rated for? I was happy with my 2nd Vig, the first one was too loose and I was blow through it. Do you have any graphs of unlocked pulls?
P.S....

Bob, cna you add on that engine girdle unit? I understand the logic of the piece, but since you installed first hand, what do you think? Any modifications to the block, misalignments, etc?
Car looks really strong. I will say that i wasn't impressed with the rear mounts, however, with a bit more engineering like this form EPP, they can be matched well to produce good power.
Get a t76!!!! and switch to those stock manifolds.... you'll love it!!
