Big PTE Core Install

[CanadianTalon]

Although you are correct in an extent, bigger is not always better in an intercooler. Pressure drop as well as how well it flows are moreso what will make the difference in the end, rather than the size of the core. The problem is that most "bigger" intercoolers have a higher pressure drop than a small ( good ) intercooler would have. This is where the spool up comes into play. I do agree that on a t25 there won't be a noticeable difference in spoolup with a larger intercooler, but the reason is that turbo has no lag to begin with. If you have a scm61 for example and run a small / efficient intercooler and the throw a large intercooler on there I guarantee you will notice spool differences as well as SLIGHT power differences. I suppose it's like an injector, you can run a 1600 cc injector on a 16g car just fine if it's properly tuned / supported, but why do it? Now in his case he said he will be upgrading to a gt35r so the core he chose is perfect. I guess everyone has different thoughts and ways of looking at things, and without real life data taken at the track with the exact same conditions we won't know what the difference really is.

I've talked to people who have moved from a modest sized front mount air/air intercooler to a passenger seat or even back seat mounted HUGE air/water core with a TON more piping in mustangs and camaros and reported no difference at all in spool. That's a much bigger difference in charge pipe volume than going to a fairly large air/air core like this, so I don't think you'll notice anything.

The 4 people I've talked to were running: GT47-88 turbo on a 331" motor, 91.5mm turbo on a 402" motor, twin T74's on a 370" motor, PT88 on a 306" motor. 4 people who went from a few feet of piping and an air-to-air core in the bumper to 10+ feet of piping and a massive air-to-water core mounted inside the car. They all told me they saw zero spool change moving up to the huge intercooler. The only one that was online was Brent from turbomustangs.com, go ask him about his real world experience. 1 cubic foot of core size isn't going to mean anything in terms of spool.

nice looking welds!


nice vest, have the same one in my locker

Bigger usually equals better with intercoolers, even on the T-25. The added cooling capacity coupled with the less restrictive core more than makes up for the volume difference.

i ran a 14.7 bone ass stock.... threw on a fuel pump, front mount, and and intake, and ran a full second slower. This was not due to bad driving either. I got in 24 runs between the two times at the track and my best times for each trip were a full second apart. The t25 took waayyyy too long to fill the ic and i couldnt keep it filled off the line or inbetween shifts. Yes top end it pulls MUCH harder, but low end is where i lost valuable time getting off the line. 1/4mile a larger IC hurt my performance, highway cruising it helped

Bullshit.

Maybe the car had a boost leak, or something went wrong from the pump install, but I've never seen, or, for that matter, have heard someone losing a second over a fmic, pump, and an intake pipe.

If you lost all that power then you def didnt do something right, check for boost leaks and such. There is a tech article in here that adds like 3-8 whp just by going through all your pipes and checking all leaks rtv'ing everything and just bascially doing basic maintenance on your vehicle. But I have noticed a big huge diff w/ my 255, big pte core, 16g, 550cc, safc, and dejon tool mbc from rre. WOW , not as cool as my cbr though but almost close enough.

I'd say you have a pretty decent sized boost leak as well. Usually cars will run the same before and after with the mods that you added on a t25.

pressure tested the IC system 2 weeks before i ran it at the track, and held boost to 24 psi before i stopped. Like I said, i gained tons of top end power, but the time it took for my turbo to fill the IC took waaayyyy too long... just long enough to slow my 1/4 by a full second. Install on the pump was flawless, i had 3 other dsm'ers help me do it back in the day. It might have been starting to go bad perhaps, but i doubt it since i've upgraded many parts since then and have had no fuel issues. FYI, this was a while ago when i ran those times, i've had 3 different turbo's since i made those runs

2.5" piping, and a 26x9x2.75" core i think is just a little too big for a t25. My B16g had no problem filling it, nor my 20g, and i dont plan on my new turbo to have a problem with it either

yea no kidding you felt a difference, you put a upgraded turbo on there I think i had just outflowed the little blowdryer of a t25

dude, when you're racing, isnt the motor usually hanging out in the topend of its rpm range just like when highway racing? Get a clue, kyle. Your post made me laugh.

You have not outflowed the t25. your car is running 15's and you think you outflowed it? Kyle, lets work on your car a little bit before you start posting allogations about t25's and flow dynamics about intercoolers and topend power bla bla, ok?

Since when did you ever have a 20g or 16g on your car?

Damn black your out to crush all these noobs today arent you??

OIC, I cant beleive people are still posting in this thread.

Now that you know what was involved with making your own pipes, how much extra money would you have paid to have a nice piping kit all done up prebent with couplers etc instead of fabricating and welding all your own stuff.

 

[1fast97gsx]

I spent a total of $700 for my pte large core, 2.5 short route upper piping, 2.25 lower piping including welding, clamps and couplers and I did a quick polish on them myself. Sure I didn't save much, but this way I got the pipes to fit with MY turbo, run short route, be flanged for the bov I wanted, and still be able to run a gm maf and look clean. If I would have bought a kit there is always something that doesn't fit or needs to be modified so personally I'm glad I did my own.

Well since the cost of the core went down, and I have freinds that tig weld, I would recomend this for anyone, becuse now you can get this same core for $450 and have short route pipes, or long route pipes for less that $350-$500 so why not pay $450 for the core and $150-$200 for pipes rather than spending 1k on a kit from you guys or sbr or whoever else, btw imo fmic are so over priced anyway. Its awesome that these companies are overcharging the sh*t out of us on such an easy product to make.
