Murray, do one or two runs with the hood closed to see if engine bay heat will effect the gains from the intakes, that could also guide you whether to look into a long tube Cai versus short ram... To be frank I may go short ram if you get good gains, I'd just have to figure out some sort of heat shield

It's not going to really affect anything unless they do the dyno runs with the hood closed and no fans blowing. Then "heat soak" might come in to play. Do a search for heat soak on here and you'll find threads where guys have posted intake temps testing that theory.

Speed holes for speed...make your own ram air boxes.

Some aluminum sheet metal, tin snips, a rivet gun, rubber door seals, and some free time!

Where did you get the little aluminum tubes for the pcv your making? I needs one and I can't find them any where

this will be interesting. the de was choked from the factory, to this mod would help. not sure about the hr though. im guessing some better peak power with a drop in low rpm power.

Here's a pic though to hold y'all over

Murray, are those intakes just resting against the shock towers or did you fab up some sort of support for them?

He's going to fab up some kind of support braces for them while Bobby has the car on the dyno i believe.

He's basically having to retune my car from scratch because the larger MAF housings like ****ed everything up.. i think he said something about redoing the whole maf table.. im sure you knowledgeable tuning guys know what he means? here's a little video of initial startup lol. sounds like cam lope

Jeez

I should've mentioned that Yeah you'll have to retune the MAF table because now the motor is seeing more air than its stock MAF is metered for.

We had tthe same issue in the BMW community when going to larger MAF, it was common to swap in a Porsche MAF, but then it required a bottom up retune.

Considering cin knows what they're doing I'm sure you'll be fine. To be honest, increasing the MAF diameter from the stock 2.5" IIRC to 3" will actually produce some considerable gains across the board, I think you should see gains across the whole rpm range, fingers crossed!

My opinion based on experience on a whole different car granted, but now your car will be seeing more air so it should in turn make more power as a result.
