Car under knife at Speedriven ;)
So finally I got around to take the car to Speedriven and start getting it ready for the new season. I purchased the car from a good forum member on here that did the ECU/TCU Tune from Speedriven already so that came handy having on the car and sure made it fun to drive. With the summer heat in Chicago car fell on its face after a few good pulls. I decided to go ahead and get the cooling issues all sorted out for now.
I'm doing
Front Heat Exchanger
Rear Tank
Speedriven IC Pump
Catless Downpipes
I'm also thinking about the intakes.
I will be doing the Intercoolers as well this coming summer.
Do you guys think I will gain from intakes before the intercoolers or leave the stock air boxes for now?
Thanks

I would think you need the extra capicity of the larger intercooler to even handle the extra hot air your engine will inhale with an intake that pulls hot air from the engine bay. You are much better with your stock intake.

would it benefit to remove the front grille at the track or race event ? This would allow a lot of air to come into where the intakes sit.

Has anyone ever put an IAT sensor at all four filters to see if what you are saying is true? There may be air that is a little cooler at the tip of the one filter pointed toward the front but the other one on top of the engine is just sucking in HOT air. Make no mistake that air is still much hotter than it is outside the car. There is not enough cool air blowing though the front that will offset the heat generated by the engine and the hot air being put off by the radiator.
The only way I see that intake being effective is if the filter on top of the engine was pulling air from directly above and louver the hood and isolate around the filter so it can't suck in the hot air. You would also need to isolate the front filter pointed toward the front gill opening so it can't suck the heated air from the engine bay and radiator. You would make more power if you started with cooler air than what is sucked in from under the hood. Every 10 degrees in IAT cost's you 1% HP. By sucking in that hot air, you make your intercoolers less effective so your actual IAT's are not as cool as they could be with an ideal system.
An intake needs enough flow so the power isn't choked but their intake is less than ideal. A little isolation from the engine bay heat would be ideal. Start with a hot engine and try dynoing with the hood closed and see how much power it makes. Then, open the hood and let it get cool air and you will see some good gains in power.

I ve got the solution, a meth kit. Marcin actually sold it to me about a year ago and never got anyone to install it. It's for the 65. I paid $325 for it and will let it go for $250 shipped. It's brand new still in the box. I also have off road intake pipes for the track only and a drag pack still for sale

This is the ultimate solution. I run a Meth kit on my supra and it makes big power on pump and meth.
