turbo goes directly into Ic, gets rid of about 3 feet of intercooler piping. little quicker spool. and its full race....

I agree with the above comments but I have also heard that if it is not used with the Full-race mani and downpipe that it has a chance of not sitting in the center of the front bumper .It will be off to one side and correct me if I am wrong this is what I have been told and have no personal experience.

It won't spool any quicker.

A typical honda moving 30 pounds/minute of air is consuming around 10.3 cubic meters of air. That's around 0.17 gallons/second of air. Lets say your average turbo setup has 6 feet of piping, and an intercooler that holds 0.0186 cubic meters of air. Keep in mind that's a huge intercooler, that's how much the PTE "750 HP" intercooler would hold if it was a big empty box. 6 feet of 2.5" piping holds about 0.0058 cubic meters of air. That's a grand total of 0.0244 cubic meters of space for all the charge piping, etc. That means the air is moving at about 422 m/s to reach your motor. The 3 feet loss in charge piping means the air is going to reach your motor ROUGHLY 0.00777 seconds faster.

Dude, did you feel that? Boost came on like 8 milliseconds faster man, that ROCKS!

its what i have been told, now i dont feel so bad for not buying a backdoor IC. perhaps a new bandwagon? PTE "600"hp IC will do me fine, and its cheaper than full race you dont know how happy that just made me lol

Another thing you have to consider with the backdoor is I don't think the air coming out of the side of the end tank, and smashing into the opposite wall of the end tank before making a 90* turn is extactly good for flow too. Not to say it's a bad cooler since Ballard is making a boatload of power running one, but I prefer a conventional end tank setup, or if you can a vertical flow core. The vertical flow cores are the best, instead of making each tube longer like in a side-to-side flow core, you add more, shorter tubes with a vertical flow. This is said to improve the cooling capacity of the core.

I don't think the PTE intercoolers are a bandwagon though, they have high quality cast end tanks, ultra efficient garrett cores, and at very reasonable prices. I remember reading on here a little while ago about how tygsr made 593 WHP on the PTE 600 HP cooler, and people were asking him if he thought it was getting inefficient, but he said Jasen Pennman ran the same 600 HP PTE intercooler on his Del Sol when it was making over 700 WHP and they both had very low IAT's. It's hard to not run a product that is high quality, very reasonably priced, and performs extraordinarily well.

I've talked to Geoff at full-race regarding there backdoor intercoolers being centered.

There 20" long intercooler which I think is there standard one is slightly off centered. You would have to be around 18" back door style" for it to be centered.

The reason I went with the backdoor setup is because of my traction bars. I ran into a problem with the piping fitting correctly on the driver side because of how low the turbo sits. With the backdoor style I just eliminated that piping.

I got my back door style intercooler made through Earl/PWR.

I think it's the same either way... Turbo goes directly into the intercooler. Less pipes to potentially blow off.

Not quite a perfect pic, but the only one I could find of TIMMAYs single slammer with a backdoor intercooler. It is pretty much staight in the pics, but with out the fan in the way, it isn't even close to centered.

you might be VERY surprised. your math is far from accurate unfortunately becuase it does not account for any losses, which there are many.

If you want to back your statements up, take the car for a ride, before and after shortened piping. Evo guys take about 4-5 inches out and gain 7-10 whp and a slight spool increase. On a small turbo drift SR20 we just did, we got rid of 2 1/2 feet of ic piping, and it made a night and day difference in response. like a "holy **** it feels like the boost went way up" difference

I am running a double backdoor IC on my Integra.
It is 25x9x3.5 bar/plate core. Some cutting required, actually saved myself 5+ feet of intercooler piping when used in conjunction with my top mount.

We switched from a front mounted cooler to a larger cooler in the back seat to a friends car, felt and logged absolutely zero difference in spool. Turbo is mounted on the drivers side of the engine compartment, so intead of it just cutting through the fenderwell and into the cooler it looped along the top of the rad (to avoid PS pump), into the other fenderwell, through the quarter panel and firewall, down along the sill of the door, into the back seat, into the cooler, then from the cooler along the center console, up under the dash where the heater normally goes, through the firewall and into the motor. Spool up was no different, didn't take any longer to build boost on the brake, and this is with probably 15 feet of piping added.

If you can show me some data from other cars showing gains, or that the "backdoor" type cooler flows better, I'm all ears. But my personal experience from the cars I've worked on and see tells me otherwise.
