Gains on PTE Intercooler?

[onefastgn]

Would it be a noticable gain to change for my Stock location ATR 19 row Intercooler with 2 1/2 inlet and outlet to a PTE frount mount Intercooler?I just wanted to know because I wanted to get the most gain for my money.Combo below...Thanks

The intercooler should help it out a little bit, but your not going to be able to tell for sure b/c you swapped the turbo. I would see how it does like it is before I bought another intercooler. my .02

Thanks matt I will try that first.To be honest I didn't even think of doing that,Sometimes I think I could have saved my self alot of money if I were to just ask some questions before making a bunch of changes.I was just wanting the best bang for my buck.Thanks again

What kind of ET's are you trying to attain? I am shooting for 10.30's/10.40's with mine.

 

[onefastgn]

Matt

I'm going for low 10's too.Hell might even try for a high 9 if that is possible.what all have you done to your gn to get low 10's?

 

[smokinttype]

I have a 70 GTQ .85, front mount, 75's, billet converter 3500 stall, ported irons 218/218 etc etc



I have been a 10.91 on with my old combo of te45a .63 and a stretch. I just didnt like having to run soo much boost, its pointless b/c YES you ARE making more power with the boost 30-35#'s but your shooting yourself in the foot b/c you are sending all that heat through the motor. I just like to run less boost and be more efficient so my motor will last I will be running my new combo real soon as I am waiting on a Hobbs switch to get here so I can crank my boost up and try it out.

 

[onefastgn]

All my runs were made using 25 psi with the 45 Just like you said I didn't really like running all that boost.My heads are Iron and are o-ringed and there ported by chamption,but running lower boost just make me feel alot better.Are you still running the stock MAF set up?I just changed to the LS1 set up It seems to be working fine so far.I'm also running the ATR 309G hyd roller cam package with all four main caps.I was hoping to be able to run faster with the 72 with out having to run so much boost,Thats really why I was thinking about the F/M Intercooler instead of the ATR that I have now and keep the air temp down as much as possible.Good luck with your new combo sounds like you should hit your goal.Keep in touch and let me know how it runs....

I am using an extender chip with the 3.5" maf and translator box....25#'s of boost is more than safe, heck I wouldnt hesitate to run 28-29#'s so long as you got a good fuel system.

 

[onefastgn]

I have a good fuel system just didn't want to do any damage to my new motor so 25 psi felt good to start at.Is your extender chip the extreme?Sounds like we have about the same stuff.What is the fastest you have heard of someone going on the combos we have?Are you still using the 200r4 trans?I went to the 400 bop I was tired of having to rebuild it,and boy what a difference it is having a 400 yes I may have lost a few tenths but its more then worth it Its saves me money in the long run and if I keep going faster atleast I know the trans will hold up for awhile.Do you have c-clip elimators installed or are you still running the stock ones?Sorry I have so many questions but I would rather take care of something before its to late or I get into a bad accident.Give me a call some time if you get a chance I would like to chat,about some stuff...Thanks Tony 1563 5293990

Question

Matt are you running your stock headers still?

 

[smokinttype]

Tony,

I was going to call you lastnight but I didnt get in until late. Yes I am still running stock headers. I will be able to call you tonight. Talk to you soon.

The air intlet temps into the motor are pretty impressive with one of Jack Cotton's front mounts. You may want to look into one of these.

Wow jacks Intercooler is$1150.00 compared to $850.00 for the PTE intercooler,Is there that much difference between the too?And how much cooler will the air temps be from one to the other?But thanks for the Info Jason,I assume you are using one yourself (Jacks frount mount)...Unless someone can show just how great of a performance gain are from a PTE Frount mount to a JC Frount mount I see no reason to spend the extra dough.Just want to get the most for my money.I hope someone can help out on this question.
Thanks

Might do a search and read up on what's been said.

IMO, keeping the intake temps., as low as possible is cheap insurance, and I'd rather error on the side of having more then enough instead of just getting by.

I would appreciate any Data that you could find or tell me where to look.Thanks Tony

Bang for the buck can get very confusing. In this case I would lean towards the PTE from a $$'s only stand point. From an I dont want to second guess myself a few months down the road stand point I would get the Cotton unit and never look back. Once its paid for and you've had it for a few years the $300 wont seam like a big deal at all. It will probably seam like a bargain.

Lower intake temps build more HP and minimize or eliminate detonation. I can not under stand why a guy with a street car that sees alot of time running on pump gas doesn't MAX out on intercooling to help prevent detonation. I also do not understand why a guy who's setting up a car to race doesn't max out on intercooling to try to build more HP. For a guy who's trying to do both............ I'll never understand.

thanks for the Info Jason,I assume you are using one yourself (Jacks frount mount)...

I have run stock, BGC stretch, PTE front mount, and I now run an ATR liquid.

PTE front mount uses a better and more expensive core than the ones CAS used. BUT air flow across an IC has a HUGE effect on its efficency. D/T the over heating problems I had once I switched to the PTE front mount I felt the airflow through it couldn't be too good unless the car was up in the higher mph. The PTE end tanks block alot of the radiator. The Cotton unit does alot better job of matching up to the radiator and should have alot more flow accross the core. My buddy Surej runs the Cotton FM and his inlet temps are very impressive. To me his inlet temps show that the Cotton FM is sized properly and has enough cooling flow accross it to be very effective on a low 10 second car. Infact it runs close to whats considered the limit of maximum effectiveness for an air to air unit.

Wow jacks Intercooler is$1150.00 compared to $850.00 for the PTE intercooler

I paid $1200 for my ATR liquid used! I then added another $300 to $400 to set it up the way I wanted it. I'm now considering going to dual stage intercooling where a front mount will zap most of the heat out and then my iced down liquid can be used to drive intlet temps into the 50* to 60* range.

HTH: Jason

 

[onefastgn]

I see what you mean.I too know Surej I am the one who sold/traded him the BGC set up from my old motor.I also sold a $15K 1150 hp 1040 FT LB TQ stage twin turbo motor to my friend who put it in a truck I'm sure you will all see it this spring over there in Chi town looking for someone to race Tell Surej to get ready LOL.How fast have you been jason?Well from what I've read and from what other people have said I think I might go with the cotton's because I do not want to do this again.and like you said the $300 won't be so mad later down the road.Thanks alot for your time Jason.Tell Doc I said hi,and will get together sometime this spring.Thanks again for the advice.

How fast have you been jason?

I've only gone 11.16 @ 121 w/ 1.60 sec 60'. Thats respectable for a bone stock 100k long blong block, but I was looking for more. Lack of visits to the track hurt me the most. I only had one try at the track with my motor running right but 3 lb launches and way to much T-conv slippage killed me. This visit was also my first and only try at the track with a new fuel system and I was trying to tune it out. I had previously pulled 1.4 second 60' times with my best being 1.462 with 8 to 10 psi launch. I had also ran almost 99 mph in the 1/8th but only 121 in the quarter. I was grabbing Over drive way before the end of the track and the car was falling on its nose the last couple hundred feet. I never pulled high 1/8th mph and good launch on the same pass.

Hind site:
I should have took my car back to the track with the old set up. I should have dialed the fuel in real good on the street. I should have fixed my brakes so I could launch in the 8 to 10 pound range again. I should have held the car in drive a little longer to cut down on how much of the track I was running in O.D. But I had my one chance and 11.16 was all I could muster that day.

I went to a 4200 rpm switch pitch turbo 400 set up and a dual ball bearing 66 p-trim. I was hoping for 125 mph and low 1.4's on this new set up. Instead the switch pitch tranny kept hanging up in first gear, I over reved the crap out of my motor, was bouncing in and out of fuel cut out and ignition cut out, boost was bouncing up around 30+ psi, and the head gasket finally went pop! Like I said, I now kick my self in the butt for not trying another time or two with that old set up. I'm now building a 270" stage motor with stage 2 heads. Trust me, I will make sure this tranny is shifting right before I start pooring the coals to this stage motor.

Surej and I talked about the Cotton front mount a few times. I kept saying to him that since he had already gotten himself curious about trying to run it that he would kick him self in the butt if cheaped out. I can't talk for Surej, but I think he is very pleased with the IC. Surej has what I consider to be probably one of the best street strip set you can put together for a GN.

wish me luck: Jason

Jason we should all get together and go to cordova drag way this spring.There is some 8-10 gn here in my town.Sounds like you will be well into the 10's this spring.That 99 mph in the 1/8 th is a solid 10.90 pass.Man your 60 ft are killer hell mine are only1.57 with about 7 psi and 102 mph in the 1/8 th.All that I can say is once you go 10's you just want to go even faster,I'm sure Surej will say the same,Atleast you have someone that can give you good advice.Good luck this spring and stay in touch....Tony
