She got some sexy new shoes! I just got them on her this afternoon and then got called out to a job so I only got this one picture and didn't even get a chance to clean her up. These things fit sooooo nice. Much better than the Pro Stars. No grinding required so I look forward to replacing my calipers with ones that don't have any weight reduction. LOL

yeah, i apologize about that, it was in the previous post, i just got done reading all 25 pages. Dude, i wanna say thank you for this thread, you've really answer a lot of my questions and gave me a a lot of helpful info on my build. Im new to the turbo scene so i had a lot of unanswered questions, but this thread has been a very big help. im doing a similar build to yours, i was gonna go 408 but i was told with that turbo i would have back pressure issues, is that true ??

Yes. Even the 370 ci that I am running is a bit much for this turbo. It would be happier at 347ci. There are many other benefits to not running the stroker set up as well. I've blown up my share of strokers.

Just read this whole thread. I love the car man.
Im building a very similar setup (370 + pt88) in my 79 camaro. Since you've been through everything already I was just wondering If you were starting in my position would you do anything differently?

Yeah, I wouldn't use a PT88, specially if i had the room under the hood that you have. I would use a 91mm with a T6 flange, 94+mm exhaust wheel and a 1.0x AR housing.

well I already have the turbo. If I can go as fast as you have with this setup I'd be happy. The car with the old alum block ls1 & t56 weighed 2880 with me so It might weigh 3000-3100 with the TH400 & iron block.


As far as cam & head & injectors what would you do?

The problem is that the turbo is out of breath early (like 5800-6000 rpm) and boost will max around 23-24 psi. At your weight it will run 8.4-8.5 though.

You can lead a horse to water........

Finally got out to the track after about a year. Since my last time out, we put in the Holley Dominator EFI and the FTI Powerglide with the 1.80 first gear. We are also working with Holley and field testing the Boost control that will likely be available towards the beginning of next year. So the AMS500 is sold and gone. We are testing it with CO2. This will just be a free module upgrade to the Dominator and HP ECU's software as I have it understood. You will just have to buy the solenoids and transducer to measure the pressure in order to regulate it. I can answer some general questions on this but can't get real specific yet.

Because of all the changes, I decided to go easy on her first time out. Ran about 10.5 psi (175-177 kpa) all night. Boost control worked awesome so I figured that I would focus on the 60'. Started out at 1.52 and worked my way down to a 1.40 over 5 passes. Still have another .1 to drop in order to get to my normal old 1.30's. I was hitting it with alot more power to get those 60's but since I have more power to give, I'm not sweating it.

Passes were 9.7X-9.8X with MPH in the mid 138 range with the exhaust completely sealed up thru 2 mufflers and a single crush bent 3" pipe out the back bumper.

What does the boost controller program look like is it in real boost or like the ams adding boost to what you start with (I have a dominator system with a 5.3 with a old nmra legal large fram 85mm non-intercooled with their water/ meth need two more 1000cc nozzles)

I was wondering if you happy with the change to to the glide from the 350 and what rear gears are you running

In it's final release form, it will be able to do target boost or target dome pressure (like the AMS). Target boost is far more complex and they are still working on it. There are alot of variables involved in that.

We are testing with target dome pressure. So to make the 10.5 psi that I was running, I have to apply 15 psi to the top of the gate (dome) with the CO2. On the WG spring alone, I only make like 4-5 psi.

I'm happy with the glide. Just have to get it figured out. Because of the huge difference in the first gear ratio from the Th350, you gotta have a good bit more power in sooner in order to get this 3850# pig in motion. Because of all the variables at play, I was taking it slow. It also seems that I am coming off the gas pedal on the launch and unloading the suspension for a split second. I might need to scoot my seat forward a little more.

I didn't mean to sound unappreciative or rude. Changing turbos just isn't in the cards for me right now.

I value your input & look forward to hearing more about the Holley boost control.

If Im running a stock PCM what would you do for injectors on E85?
