heat soak??I know its not a turbocharged car BUT ALL my turbo cars run VERY similar intake setups and ALL have made some pretty good hp gains! (although factory airboxes were very restrictive)but like earlier posts just wrap pipes and use bigger filters and maybe some sort of heat deflector.

As for the filters being too small, i agree. It's the best we could find without ordering K&N's that would allow for them to be down closer to the intake vents. The reverse conical filters that are in there now flow pretty well given their small size. Cars going away for the season soon so new filters will get thrown on before next spring. And performance loss due to heat intake is not as severe as you guys make it out to be. The amount of air flowing under the hood through the gill at even 40 mph is plenty to keep temps down. Of course the filters dont help, but that will be solved with different ones. The tabs on the intake vents were cut on both sides allowing for more air. The only time your going to POSSIBLY notice a loss is sitting at a stoplight on a 90 degree day. Even if it did loose a few HP overall, say 5-10, It would never be noticable on a 470 hp+ car. I didnt notice any loss or gain under regular or hard driving. The added whine of the supercharger is well worth the cheap money spent to make it, even if it lost a few HP. The pipes will be wrapped along with new filters next year. Still was able to pull a quick 60- 120mph on the highway to embarass some punk in a ricer

Hey do you have a obd2 scan tool that you can monitor temps?also wondering what your coolant runs at. Mine just threw a code for coolant to cold and I don't know if my tune adjusted the temp when the therm kicks on or if my pump id stuck on.
It came on last night and it was about 29-30 out
Tonight was 45 and it never went over 187 with hard driving and was around 180-83 normal driving.
We can compare intake temps too since we're local

i know everyone wants a better setup for airflow. i dont know if you can fit thru the rad support and behind your grill but this beast is king for the 32 engines
full 3" teflon coated tubing to a 3" silicone y splitter at the t/b. high flow k&n filters up front. the drivers side has a 2.75 " reducer to allow passage thru the rad support without cutting anything.
heres some flow data from rob to show the increase.
stock slk32 intake = 446cfm
sl55 intake = 514
sl55 with devil horns = 531
single CAI with teflon = 602
dual CAI with teflon and big filters = 748
this setup shows a 20 rwhp inc in the s/c 3.2 engine in my 32

I might do something like that,but only do the front filters where he did them in front of the rad,I will keep the rest of my setup the way it is and take the filters out of the renntech box!
so basically adding the filters up front and hooking them up to the python tubes.

if your set on keeping the oem setup call rob for his "devil horns" they will help direct more air to the boxes.
you can see form the flow # the oem flows substantially less than the dual cai

hers the link for your to enjoy. test were done on a flow bench

skratch i understand the concept of the renntech tubes and boxes. i tried sl55 setups slk32 modded airboxes with stainless tubing and devil horns homeade tube sets like the dual cai but all had so much turbulence you lose airflow. regardless of the renntech top the air still has a 90* direction to go and pass thru filters in the middle of the stream creating turbulence. i wanted more than anything to keep my center logo and the airboxes but flow # dont lie!

You have to appreciate the actual testing that was done and the results speak for themselves!
I am sure a filter change will make even more of a difference. Either the XStream K&N's or the Weapon R SW velocity filters would do the trick!

the filters on mine were dirty b ut cleaned and oiled now. the problem with using bigger filters is fitting them behind the grill. i actually had to have a custom grill built to house everything in front. not cheap!
i do have the xstream k&n's for the track. remove the grill and let em flow!!

needswings is a first rate shop. they test everything they have on their srt-6 at the track for real world results. a member on the xfire forum named woody is the genius designer and he has a desire to tear everything apart and make it better!

Stock SRT-6s have gained as much as .5 seconds in the 1/4 from just the NW dual intake alone, no tune.
