blow-thru boost tube

04_Sti_Man · 01-12-2008, 04:22 AM

I'm going to make my own blow-thru maf and was wondering about a couple of things?
1.does the intercooler pipe have to be a curtain size?
2.can i just loop or block off all the vac lines running to the intake?
3.what is the sensor on the inner fender well behind the block off plate?

thanks in advance.

I dont have any answers to your question but just wanted to warn you to be ready for some extensive tuning....I just had my car tuned and it took nearly a week to get everything running properly with the blow thru setup....

anyone else have diffaculties tuning with the blow-thru.

and what problems accured with the tune?

I bought the perrin 30r turbo kit and the only way to retaiin the maf is to add a blow thru boost tube

If you are going to do it i would recommend buying the Perrin blow-through boost tube and, getting a good tune. unless your a good fabricator and have the right tools, buy the boost tube.

i can make one just the same as theres if not better, whats the diffaculties that made it so hard to tune?

i had a blow thru on my eclipse gs-t and the tune was simple.

or you could get the maf bracket off an intake and cut the intercooler pipe so the maf can fit in that spot on the intercooler ($50 or less after silicon hose and clamps)

very true, but i hate couplers blowing apart so the less there are the better for me.

I think I read that the pipe diameter around the MAF has to be same as stock, or it won't read correctly... makes sense, but I'm no expert.
