I've had an Epiphany. I think the reason my boost pattern, 10-8-10, has not increased (lucky me) with all the intake/exhaust mods I've done to my FD is because the Blitz intake/filters are sitting on this platform which is preventing access to better air flow. Basically, the intake/Filters are "boxed" in.

So.....I'm going to cut a hole in this platform and build an Air-Ram System that will connect from the R1 lip up to the bottom of the platform. This will blow fresh cold air directly into the filters.

Question.) Will the Boost more than likely increase as a result of this unristricted cold air flow AND/OR will this cold air flow in it by itself help create additional H-P's. Profec B, here I come!! Thanks for you input!!

 

If you could find a way to effectively produce a ram air to the intakes, I think the only benefit would be the lower intake temps from the fresh air. I'm not to sure that it would help your air flow into the turbos too much.

 

I think the air flow results will be very effective. Please explane to me how better, colder air flow going INTO the intake pipes CANNOT help the air flow going into the turbos. Are the intake pipes not connected to the turbos? (rhetorical question). Thanks for your input.

 

My original thread from last october somehow got deleted, but here was my results:

Agreed, I have done some extensive testing on my stock box to get my trap, then modified it tested it to get my trap. then I got an rx7fasion (same as M2) intake and then got my trap, then I modified it and got my trap.

stock airbox no mods to the air box
Average trap 104.X
Best trap 104.X

stock airbox mods to the airbox
Average trap Low 105's
Best trap mid 106's.

Rx7fasion airbox (unmodified) and midpipe instead highf flow cat
average trap 105
Best trap 106's

Modified RX7fasion Airbox same mods as above
Best trap 109.86
worst trap 109.56

I have backed this up with about 50 timeslips, btw. This is not just doing 1 or 2 runs, I had substantial timeslips. Your trap speed does not lie. What I found was that the stock airbox (though boring) has the exact same HP potential of the aftermarket cold air boxes. You will notice I had to modify my cold air box to really get a good trap.

I just made a new modification to the hose that I routed from the nose of my car, and I expect to get 111-112 traps next weekend.

It will help you get more boost in the gears, too.

 

Awesome comparisons. It's obvoius that an unrestrictive fresh air flow really produces more H-P gain. Please post your findings after you get back from the track. Thanks for sharing your valuable info. !!
