I am going to buy a new Waste gate from SFR and wonder if I should also get the upgraded IC from SFR as well. SFR and LR are both selling a IC up grade but all it really is, is the same IC with one of the ends reworked. Both say it will move more air and cools the air better as well. I now have the LR full 3" exhaust, LR Boost Enhancer, LR cone filter set up and also increased the fuel pressure because of the exhaust. SFR is dropping the cost of the IC to make me think real serious about it. SFR IC just pretty much whacked off the end and rewelded a more square end on it but with less bottle necking of the air. LR had a new part cast and has a nice curved piece made for it but at almost twice the cost of the SFR one.

Any Ideas?? Will I feel a difference with the upgraded IC?

I have ordered the SFR intercooler and I will be dyno testing it in a week or so.

Do you have a Dynoplot with your current setup for comparison?

I am also wondering about an intercooler upgrade down the line, what real performance you get out of it. That and headers are my next upgrades down the line hopefully!

jgporsche

yes, right here

Just find a local aluminium welder and have your IC modifed. Thats what we have done for 4 cars.It's much cheaper way to go

spyderman

what exactly has to be done to the old intercooler to up grade it? which end would you have to have welded or fabricated?

Check out this pic of my friends car.

Awesome, your friend uses his headlight washers for an IC sprayer. Am I right?

Olli Snellman

You are right

Whose car Olli? Isn't Andrew Cooper doing that as well?
as for the topic, wait until you see some dyno evidence before you make a choice. You don't HAVE to do it immediately. SFR makes products EVERY BIT AS GOOD AS LR. There are some other options out there as well, but if you're not going racing, they will only help you to a very cetain extent. After all, how often does your IC get heat soaked while moving, and cooling compressed air at full bosst? That's what it does when racing. That's not what it does on the street. Stop and go traffic will render your intercooler useless. It will just be a heat soak.
Once you are moving again, you get use from it.
On a street car, everything is a compromise.

It's Pete's car. I suppose Anderw uses non original IC

Yes. He is running a Broadfoot Racing IC. It is LARGE!

From my experience you won't notice much difference in the intercoolers on the dyno. One run and the intercooler is heat soaked, even with a fan on it. Now, if you remove the header panel and set a bag of ice on the intercooler and give enough time between runs to cool it back down...

I tested the LR intercoolers, stock, stage1, and stage2 on the dyno, with temp sensors in my intercooler pipes, and at a local drag strip on a test and tune night. At the strip I did two runs with each intercooler. To be consistent I reved it up to 4K and dumped the clutch to launch, wheel hop city...but the result was the two runs with each intercooler were within .003 of each other. Stage one decreased my 1/4 mile time by .4 seconds. Stage 2 took another .4 seconds off. It was a VERY hot and muggy summer night, probably not too good for intercooling.

I don't remember the same numbers as Lindsey Racing has on their web site and have lost my time slips from the testing (It was 6 years and 3 cars ago). But since the claims on the Lindsey site are lower I guess it doesn't matter. On one stage 1 run I blew a connection on the intercooler (probably from the swapping), scared the bageebees out of me, I thought I blew a motor.

So RDK your saying a stage 2 lindsey unit is worth .8tenths in the quarter mile??That is a huge amont of time for 600 dollars
