Seems the tech articles Ive read so far along with some posts all agree that an intercooler is a fix all for the issue of KR. This cant be true without a catch or obviously everyone would have one. What am I missing? Should I consider this as a first mod? (after the downpipe) Ultra cheap comes first.

If everyone had an extra $1200-$1500(IC,inj and logs) than they would have an Ic.

The catch is you can have a fast street car They help with KR but it will also help in with performance I have seen just adding a I/C, N* , Headers, and a tune will get you in the 12's its one of the more expensive mods. IMO the first mod if you plan on going deep into modding is the Trans fix it first then go from there

the catch is that you lose some boost and have to spend $40 bucks on a smaller sc pulley to compensate

and the price kinda sucks...

just bought fuel rails, ported lim, full size ic stage 3 and biggest rad for 800 bucks instead of 1500 brand new

i havent installed mine yet so i cant talk much but what i heard from ppl is running an intercooler wil make every other mod worth it

im running a 3.4 with about 4 KR on a hot day maybe 5 or 6 sometimes on WOT
with IC im expecting to run a 3.1 if not 3 with rockers KR free

Sam, if you plan on running a 3.0 pulley you will more than likely need bigger injectors. Most people say that a 3.1" is the lowest that you should go with stock injectors.

I was hinting on maxing out my FIs with my 3.2 at the track...
But, I'm running a GenV

The price tag says alot. On the other hand slapping a fullsize intercooler on a completely stock car is kinda dumb too. You wouln't wanna force all that boost into the engine and out the stock manifolds and downpipe. So most people would calculate some kinda exhaust work into the equation. Either all out with headers or some kinda P-log/Pems and downpipe combo. That adds to the cost.

Yeah I wasnt lookin to try alot of boost yet, I was more or less lookin at the aspect of it being insurance. All the reading Ive done lately kinda puts the fear of God in you about kr. I just wanna make sure it doesnt happen to me. Im used to moddin a Firehawk and Im enjoying the price break with my GP. $1500 was about what the average mod was to an F Body, and you didnt see the gains were seeing here.

I don't understand people sometimes when it comes to playing with your 3800. Alot a people are worried about spending the money on an intercooler, but it is going to cost more than that to rebuild or replace the engine when you get to much knock! I went ass backwards when it came to modding my GTP. I removed the cat and u-bend for better flow. Then went with a full intercooler from MAP because I didn't want to get knock. I wanted to make my engine more efficient not work harder. Then came the xp cam, rocker arms, springs and retainers, and headers with stock pulley. It put 214hp at the ground. Dyno tuned! Nothing else done, I installed a 3.4 Pulley. I went from 6psi to 10psi. With the 214 tune and 3.4 pulley I made 231 to the ground. Then I dyno tuned it for 281 to the ground. I made 50whp with just a tune. Degrees of Knock!!!!!! My stock injectors are almost maxed out. 12.1 to 1 a/f ratio. 26* of timing.

The point of the story is with an intercooler you are able to make more power without having to increase boost so far to get the same hp. You make the engine more efficient. Go and Dyno tune your car. Then you will not get knock. I don't know about you but 50whp increase on just a tune is well worth the the price of $350 and no knock.

I understand your point, but I also understand that there are alot more people out there willing to dig into a 99 before theyll dig into an 06. 50 whp for $1500 is a good deal, at least in the Trans Am world Im used to, and I have a guy to do the tune...while installing the intercooler. From what Ive read, a tune isnt gonna help prevent kr as well as an intercooler...or am I wrong?

you're right

with my tune my KR was lowered from 8 or 9 on a 3.4 pulley to 3* max on a hot day..

with the intercooler im expecting 0* KR at a 3.1 pulley

intercooler is a lot of money.. but thats when you feel the gain from having a cai, headers, or even going down pulley sizes.. like i mentioned before.. its not a MUST.. but its much safer for your engine and makes every other mod worth its price..

been having my Gp for 3 years.. took me 2 years to decide on an IC...

finally did buy it

might sell it though LOL

There's no catch to the intercooler. It definitely will help your KR and your hp and tq gains from it will speak for themselves. The only downside is you will want (really need if you want maximum gains from an intercooler) a way smaller pully. And just to keep your engine in good shape, headers or P-LOGs and a 3 inch DP. Oh and dont forget the biggest downside of all. The price. The price of the intercooler isnt all you'll have to buy. You'll need those exhaust upgrades and the pully. So it comes out to be about 800 more (if you find good prices) than just the IC price. If I had the money laying around I'd do it in a heartbeat though! No downsides to an intercooler besides a sharp increase in speeding tickets. lol

I have all the mods I need to not have to spend more then the IC cost to be ICd...
I think I'd rather get a Cam at this stage in the game though...
Officially I'm a low 13sec car, 13.274 but, I believe with my tune I could pull a high 12sec run,
Just couldn't get to the track due to the economy...

I guess I feel an IC is a large expense for what I'd get out of it...
I've done rather well without one up to this point...

EDIT:
How many members are ICd vs. the ones that aren't?

i am

but its still in the box lol

the IC is expensive but i dont know why would you buy it new??

im sure you can get a used full size IC for 800 use it for a year or long maintain it wel; and sell it back for 750 or 800 again

so its not that bad

but again only you know your budget

But remember how much it would cost u to install a cam.. assuming u dunno how to do it, cause u have to take then engine apart... and how many of us would like to do that/know how to do that...
Plus almost anyone that knows how to use a screwdriver can prolly install an IC ... so id say IC is the way to go

as for the second one... same as SamzGTP... got it... but still in the box waiting for the -40*C to go away

I bought my I/C New but I only bought the Core from ZZP put together a new kit with a Meziere Pump and a Heat exchanger bigger than zzps not the frozen boost but the full size one and was still under $1000 if you piece it together on ur own a new one isn't that expensive
Core: $560
Pump: $200
Heat Exchanger: $100
Then misc lines and fittings line can be bought at local parts store (heater hose)
