Has anyone tested BEFORE and after STOCK intercooler vs 997.2, AM 3.5 / 4.5 60-130 times.

The only test I have read are dyno's which do not reflect real world air flow and especially with our duct design it is vital to get real world comparisons.

Also, I have read before and after IAT and timing difference, but what does all that mean on the street of strip?

The best real world test I have read is this thread:

- 997 GT2 w/Re flash only vs 997.2 turbo PDK w/re flash only 80km to 280/300km/h = GT2 winning by 3 lengths

After 5"TPC inter coolers in the 997.2 PDK, has the 997.2 PDK winning be a nose from the same rolls test = 3 cars!!

I would really like to see a 997.2 intercooler (or a reasonable priced 3.5" AM) vs stock ones 60-130 times to see how in the real world it is performing.


I know for the bang for the buck money is better spend on meth injection, but would like to see what upgraded inercoolers do as a stand alone.
Thanks

Bobby,
Link below but not stock vs X. Unfortunately 60-130 isn't much time under load to really stress a cooler so pretty hard to tell. You're probably not going to see a big difference in times with various coolers in such a venue on a street car. The biggest intercooler-driven gains are usually found during lengthy pulls (usually over 150mph on 15-20+ second pulls or repeated loading on a road course) where, as you mentioned, weaker cooling causes the DME to pull more timing. Unless you're making a bazillion hp, and there are several cars over 1000hp on "little" 3.5 cores, this is much more detrimental to power than small flow differences between various cores. Most street cars running the occasional 1/4 mile and 60-130 fun runs on stock motors just don't encounter these issues so its not a priority for some. If that's your only goal, than just about any cooler will suffice and I would recommend the vendor/tuner you're most comfortable with.

For whatever its worth I recall picking up ~2-3 mph in the 1/4 going from stock to .2s with much more consistency between runs. I think others have seen similar gains. Usually people do other mods during cooler upgrades so not much isolated data out there.

Here is the 60-130 test I did on 997.2 vs ETS:

Slight gains from post-shift boost recovery but had I done a 4th gear 60-130, I probably wouldn't have seen a gain as the temps were so close and hadn't moved much yet.

 

You picked up 2-3 mph in th 1/4 by going to the .2 vs STOCK!!!???

Now that is real world and what I am talking about!

You said others have experienced the same increase in the quarter going form .2 to STOCK?

I am wondering if that is true, me doing a .2 and meth injection should be more then enough for my BILLET16's and even 3076's which I plan on upgrading to eventually.

For a turbo like 3076's WITHOUT METH, I can see .2 not being enough on a long pull and you making more power with a 4.5" GOOD A.M. set up, but with meth I wonder if even on 3076's if a bigger inter cooler would really make a difference?

Thanks for your input!

 

Great thread OP, subscribed.

That is DAMN impressive!! Right now I am at 124 mph and as my next goal I would like to be around 128-130. These intercoolers will definitely help in achieving my end goal.
