He doesnt really have an official open house at the shop. Since its bascially just Andy and another full time guy at his shop,.. He is sooo busy building engines now, and when hes not at the shop, hes workin on the car....You are more than welecome to stop at the shop at any time though, he's good like that

Aaron and I saw Andy's turbo car run
I can only imagine how busy Andy is. I'm from Bloomsburg and everyone within 3 hrs of Andy's shop knows who Andy Jenson is.

The shop is still up in Nesckopeck (sp?) right? I might have to chat with yall between rounds at some point as I will try my darnedest to make the first shootout this season. Plans on running faster than the .38 from last year?
Hey, also, by chance, you haven't happend across a darkblue ta with texas plates and a procharger in the last year or so in PA have you?

I've been pondering on getting one. I just don't have any room for a bottle.
both setups seem to be nice. I prefer the front mount honestly. But why is that if it has less parts involved, why is the front mount kits more money?

OH NO, whats this.............. a PTK kit at the track. First time down the strip with his home tuning, 93 octane, full street trim...etc . This car would flat dust the cartek vette with race fuel, skinnies, and timing....lol. You see, our street cars run what the others Race cars run....lol

Look out the window...you might see some green people walking around

And FWIW , my car is street driven 5000+miles per year , it was driven to and from the track , on drag radials and ran 9.33 . And in regards to the tune , Julio from Cartek has about 2 -3 hours total tuning time on my car , my car has never been logged going down the track , never been tuned at the track , that is going to change this year . Also , the compression is 9 to 1 . The converter is the same converter I ran the previous year when my car was NA , I think it's a 32-3400 stall . I've never bad mouthed any front mount turbo kits , I went with a rear mount because it was what I could afford at the time , and my car has proven they work , up to a certain level .

just for the record, i d like to see a front mount set up that you can not see, with the hood open. I build some rear mounts for f bodies....sure front when applicable but it work. On my own car, with the hood open you can not tell its not completely stock. It would pass a california visual inspec......I ve had people look for it....even under the back with a light and no one has seen it. I did it on my wifes car as a stealth kit....and it is perfect. I have passed for a v6 car even. I even run the stock oem muffler. On side note, if I pull up to a wicked looking front mount car, nitrous car, blower car......I always win the first time even if they are much much faster. They dismiss it like MIB. BTW I also run the stock air box even.

I still like that the stock muffler sits behind the turbo so when people look under the car at night, they see the stock muffler and not the turbo even with a flashlight.

Also a P T K car will look fairly stock as well.

Jose, what 1320 is referring to is the big laughs we have had at the street races. We have had people inspecting the car with a light and they missed the TURBO!, even looking back behind the muffler and they couldn't see anything. To this day they are trying to figure out where the turbo is or even if it is actually turbo. The really does look completely stock. It probably helps that all the piping and turbo are painted black
The car has 3 mufflers, it's hard to hear it running unless the cut out has been opened. The setup has brought us many laughs on a sat night.
I've heard of hiding nitrous setups before, but never an entire turbo system

No I mean.....oem bone stock......no fuel system, no relocated alt, no headers, no visiable alky injection, no visiable pressure pipe or none oem rubber couplers, nothing.....not even a visable intercooler....its funny, really, having a bunch of car guys around your car looking at wondering if it is turboed...I even reved it once for em and they laughed.......believing it was a bone stock camaro, not a gt76, intercooled, meth injected, th400 car that would eat there lunch.
I build turbo systems, and yes when space and use let it be done I agree with putting it up front, but space and use are important considerations.

When I said I was doing a turbo versus supercharger comparison, everything else being equal, EVERYBODY said the test was invalid since I was using a supercharger cam and log header. When the turbo made 30 more rwhp, everybody said how great a test it was. If I had "optimized" the cam, then all other things wouldn't be equal, would they?

My "spec'd" rear mount turbos are VERY different that my previous front mounts.. and NOT just A/R. All I will say is if an experienced turbo designer didnt build them (design), than you cant expect the best results. Several parameters were changed from my front to rear turbo design..when all else remained the same as far as the motor and drivetrain.
I spool a little later on the rears, and make a little less HP, but its still too much for any tire I have put on.
Just as one example of one of the several specs... , I have a 71 mm's, 76 Trims stuffed in T3 ex housings (twins here) .

Zombie, that is TOO FUNNY! And one drawback to the GTO setup: the turbo is further back, and thus is both more visible AND there is no room for a muffler, making it a bit louder than a stock car.
I have enjoyed the STS...but I want the instant throttle response from having turbos getting hotter exhaust gases. I am going to be one of the "early adopters" for the Gen TT setup out of Austrailia and see how that goes. But twin front mounts with heat blankets are a bit more noticeable! At least the exhaust will be quiet...

The gto seems like the perfect configuration for a single front mount in the engine bay...enough room, check, intercooler room, check, no oil pump system, check.
packaging......just packaging.
