SHort Route vs. Long Route

[gSx_r1der]

I have already ordered this intercooler from sbr:

And I'm looking to find if there are any ill side effects to going long route instead of short route besides the extra piping and obvious?? Cause I'm looking to go from where the outlet is on the intercooler up through the stock location (being that its a 31"core only fmic not counting endtanks) and then back to the tb. Input please!!

*EDIT* I already got the 2gb front bumper!

The only difference of course is more tubing means more air to compress. A slightly lower amount of spool, thats about it, no real numbers for it.

I'm not looking at anything noticable to the normal human being am I???

PSM sent to you hak!

On your current setup, no the piping length alone shouldn't make a real difference. You have to realize its not just the length of piping, its actually the total volume of the piping and the intercooler together that determines the total effect of the intercooler setup on spool time. With your 16g and a intercooler that huge and long route 3" piping(unless you neck it down to 2.5") I'm sure you will see a couple hundred rpm slower spool then you would with a more modest setup. An intercooler that big is really overkill for anything but the most extreme goals(550-750whp), and you will have to hack the heck out of your 2gb bumper to actually get airflow to the whole thing. Bigger isn't always better, and considering your current mods and wishlist(750cc injectors) you probably should've gone smaller.

That hole is way too small, unless you want to enlarge it there is no way to make that work.

I have a cold air scoop right there bringing fresh air to the filter, I could barely stuff 2" ID piping through that hole, so it must be like 2.25"

That must be why the greddy long route piping narrows down to 2"-to fit thru the hole and keep it a true "bolt on" kit. I think if your custom fabricationg intercooler piping it would be easier to keep the piping all the same diameter and just cut the metal some. Either way 3" piping is overkill for most dsm setups, so he'll have a fun time fabricating the piping going the long route and reducing the diameter from 3" to 2.5" or 2" along the way. It would have been a faster spooling setup and much easier to install if he had simply purchased the smaller race kit in the first place.

I guess I didnt state some things clearly, I am using reducers on the intercooler to go with the 2.5" piping I'd be running, hell 3"??Is shep even running that???Come on now! But thank all for your replies, I am going to run it up through the stock piping location. If you read my profile it did say ported ex mani which, I did that myself so I'm pretty sure that hole wont be a problem(carbide bit and die grinder ) But thanks guys and I know I have a huge 31" problem on my hands WTF

Good luck with the install-please post some pics of that monster after you have it all put together, and maybe your impressions of how it affects spool.

Yea man no problem, will do with that. But I'll tell you right now if its anything like what happend today with me finally putting a cat on my car I will be very very sad, I had to lose at least 15 crank hp today just with installing the cat, such a difference. No more feeling like a feather now I feel like my car is a 3,000 lb dsm. WTF

 

[shleppy]

are you using a high flow cat? that should help or you can run test pipe year round and just re-install the cat for inspections.

You shouldn't notice any difference in spool time with the long route piping. I have long route pipes and a t3t4 57 trim and my spool is about as quick as my old super 16g. My gm mas had a lot to do with this.

Yes, I used a 3" (high flow) cat. and wow wait till I get the digi camera back and show you the difference in the weld I had a marine do for me(tig) and the weld a performance shop did for me on the custom 3" turbo back exhaust. WTF Thats the face your going to have. I have never seen a weld so beutiful. I'm def taking my custom fmic piping back to him to eliminate the use of so many damn couplers and have him tig weld my aluminum long route piping.

Thanks for the advice and help man, I'd really like to see an example of your set up to compare and contrast. So if you have any examples and or pics, then give em up.

Finally got the fmic and now awaiting one ubend and then im all set on this mofo, got the front bumper and lights on already as well.....

Yea I went long route here are some pics to the new thread of the install.

Short route's biggest advantage is less bends, and less air volume to compress for boost pressure to build.

You'll save some spool time, but setups always vary way way way to much to really make a good comparision.
