yes for now,I all must have the stock maf maxed so i was going to buy a 100mm maf and the 90mm throttle body. I'm going to put the filter in the fender
off topic terravast4 a 2.8 pulley nets you what psi

I don't have my guages set up yet. I just got them and trying to find some time but the tuner says 8.5. If you have that open filter under the hood you are just sucking in hot air.........I have the same problem.

Not at all.....just making a statement....one that has been made by one or more member on this site

one that has been made by more than one twin-screw manufacturer too!

Is it pulling timing or anything odd. Charris talked about this in post #54 in his thread, here:

Maybe he can chime in.

Hold off on buying the MAF, it will gain airflow but won't gain you any more frequency in the tune. I would first try to get the coolest air into the filter as possible. Meth will help the IATs but cannot compensate for inefficiency at the blower at the speed it is running. If you are not worried about freezing weather during the summer than run 100% distilled water + water wetter for the heat exchanger.

the added airflow (less restriction in front of the blower) will help with the IAT's/ I did not notice, do you have a 90MM tb? Any time you can take away pumping losses and increase flow, discharge temps are going to be lower.

408 Sleeper

I made an error on the blower speed. I have worked with 3 different twin screws. Anything over 2 times engine speed brings up the temps rapidly. My last effort on the 408 was with a 2.4. Anything on that combination over 1.8 times engine speed would just produce to much heat. I figured that on my built 408, a twin screw in the 3.8 range would have been about the right size.

TWISTED SilverBullet

I used to have really bad IAT's, and I'm not even running a intercooler. The best thing I did was adding methanol injection complimented by the Infamous IAT Mod, (moving the Intake air temperature sensor after the methanol spray) making sure the meth sprays at a downward angle. Then after that, no more knock retard!! hehe

This is good news!
