Bout to upgrade IC but I have heard front mount will restrict air flow to rad plus may have to cut to make fit vs bigger stock location IC . just wanting to hear some thoughts. Thanks Keith

What do you want to do with the car? 12's, 11's, 10's ? if you want to keep it mild, stock ic has no prob with a stock car down to 11.80s..some have been way faster.
anything faster then that the efficiency of the stock ic gets in the way.. stretch slic's are great but nothing beats a good fm. There are many threads on this...

Hey thanks for the info, we got it set at 21 lbs of boost with stock turbo injectors , we have alky and bout all the bolt ons. I have only had the car bout 4 months bought it bone stock and haven't had it on the track yet. I hoping to dyno it soon to see what I have to the rear tires. The guy I have had working on it said I should be in the mid 12s, maybe faster.

Imo leave the stock ic on until you upgrade the turbo, next thing to do is to upgrade the injectors and fuel pump..

Front mount would pretty much require some aftermarket fans. We sell both front and stock location IC's and front mounts outsell the stock locations about 10-1. No cutting to put one in but upgrading the cooling system is a given. Personally I have had both on my car and like the extra room in the motor compartment without the stock location IC in the way.
you can easily run into the 11s on a stock intercooler and with alky injection.the meth really drops the intake charge even with a single m15.mid 12s will be no problem with a stock turbo intercooler alky.

Huge thread on this very topic: http://www.turbobuick.com/forums/th...de-this-selection.435142/page-15#post-3625385
What about function? I want to go with a fm, but I bought a Precision SLIC. I've modified and replaced the screws with studs. So I can bolt the shroud up nice and tight. I will tack weld the little sway bar pieces and I hope to modified the shroud so I can direct more airflow into the cooler. I met a guy last year at FT and he had a plastic garbage can mounted to the shroud and it came all the way out to being flush with the air damns. Once you get going that modification I think would help drop intake temps. I plan on installing a temperature sensor in the manifold to see if it makes a difference.

I see you are new to the turbo Buick world, and the first lesson is to understand optimum performance is when you set a goal with the performance level you choose, and your budget, you can then plan a build with the proper COMBINATION of parts.
Another consideration is how you will use the car, 10% track/90% street or the reverse?
The front mount intercooler should be considered when you are at least looking for low 11's or better and a 64mm or larger turbo.
Done properly with a FM, engine cooling is not an issue, and performance is light years beyond any stock location IC.
My car with a RJC FM will run with a 10 degree air inlet temp drop from ambient on a 135 MPH run, a good SLIC could be up to 100 deg. more according to our data.

Were you spraying alky on both setups during your data collections?

I only spray!I do not spray, or drink, alcohol!
I forgot to ask, do you run gas or e85 then?I do not spray, or drink, alcohol!

Im on pump gas with Julio Alky , got a walbro and hot wire , all stock but what you can read , Mine is set at 21 lbs of boost and from what I have been told from my guys is I get a FMIC and we can turn her up to bout 28 lbs . She blows the tires now so my dilema is now to turn her up and get drag radials mounted on stock wheels or leave her as she is
Interesting, I thought the most you get out of the stock turbo was around 23 or 24psi. after that they are out of their efficiency range and just produce heat. I don't know for sure, that is just hear say.
Unfortunately I already have a PTE SLIC and with my 109 and trans rebuild, I just don't want to spend the money to buy a FMIC. Perhaps in the future.
BTW enjoy your stock setup, I wish I would have let my car stock. I bought it on May 2nd 2008 and by the first week of June I had upgraded my turbo, fuel pump, injectors and TT chip, Razor's Alky and Cold Air Kit. Didn't take but a few months before the new pump failed and a head gasket blew. Block was never the same after that and eventually the crank ended up in my oil pan. So now I'm paying about the same to rebuild my 109 and trans as I originally paid for the car.
you don't need a front mount intercooler to run 28psi on a stock turbo,i have run 30 psi on a stock intercooler stock turbo combo into the 11 sec range with a single m15 from alkycontrol.

Sorry to hear bout your bad luck MCH86GN , I bought mine stock and seen really fast upgrades cost alot . I got the car and my wife gave me a grand to start out with , needless to say that grand was gone in bout the first week . I am so lucky to have a friend that has had 2 TB but its been bout ten years since he has played with one so he had to do a little studing up on them . I am probably not gonna do much more to her , she is fast enough and have a great deal of respect for her . I look forward to putting her on the track just to see where im at , hoping mid 12s .
