SRT8 Ram Air Induction System

We have developed a Ram Air Induction System for the SRT8. Its a pretty simple design. Most of what you have seen to this point for the 5.7 and 6.1 air induction kits are just tubes connected to the throttle body that connect to an air filter over in the corner of the engine compartment with a free flowing open element filter and in some cases a shroud to seperate hot air from the filter. the mopar kit is a good example. and kits like the mopar work fine and are a performance benefit in my opinion.

we originally made a similar system and the thing that bothered me about it was know that no matter how well we tried to build a shroud to keep hot air out of the filter, that some was going to get in it.

so we extended our 3 in. mandrel bent tubing going a bit further running it down the the large opening where fresh air comes into the stock airbox. which this is an excellent design from srt. and we put our k&n filter down in this area which is in between the fender and front bumper. now when the car is moving this area pressurizes with fresh air. and thus we feel that this pressurized air will offer the coolest air possible to the motor. and rather than the motor having to suck in 100% of the air, it will benefit from having to breathe air that will have some small effect of possitive pressure as the car builds speed - ie ram air.

ok - so thats what it is. now what does it do? well we plan to do quite a bit of testing this week to have some real world comparisons. the dyno will not likely show any gains as it is a measure of power under a static state. the only way to show what this kit will do are going to be while the car is rolling. we have a VBOX data recording system that will allow us to go out and run 0-150 mph and see what the differences are in performance. the gains may be nil or they could be several tenths. anyway, we want to know what the true gains are so as we get data we will pass it along to you.

the kit will initially be available in polished stainless steel. production kits will be available in the next 30 days. we will also offer our ram air kit in carbon fiber at some point as well if we can keep the price down.

anyway, we will update you on performance as we get data this week.

right now the kit is not polished and we are building a second kit to get polished. so as soon as we have some pretty pics of the product i will post them. thanks.

.......I could draw some curves on a graph and post them right here from my own computer.......and no-one would ever know.
Exactly! I thought about posting my highest dyno run, and comparing it with my lowest dyno run. I think the highest run was done with the driver's door open. The lowest run had the driver's door closed.

I think I'm going to sell my secret "hold the driver's door open mod" which has proven gains of over 18 RWHP!!!!! I can't show the mod to you, but for $99.99 (plus shipping and handling) I will send you the directions and a piece of hardware that will allow you to successfully install the "hold the driver's door open mod" with virtually no technical expertise required.

Dyno results below!!! PM me for mailing address to send your money!! Be the first to get the "hold the driver's door open mod"!!!!!!

JMATT can your mod be retrofitted for the pink Prius VVV is making me drive until my car is delivered? I’ve got to get some more horsepower some how- I have to drive I-95 soon and I want to try and keep up with traffic. Thanks for your help! Oh- do you take Visa?
First of all - YES, I take Visa! Get your orders in!
Second, I'm afraid this mod only works on the Prius while the gas engine is running. The mod will not affect (or interfere with) the operation of the electric motors.

I don't want to give up my trade secrets, but apparently the open driver's door creates an air pressure wave that pressurizes the air intake. (Note: the SRT-8 intake is on the driver's side. Some people will have to order the "leave the passenger door open mod" if their intake is on the other side).

Finally - Marlinspike: Feel free to use the dyno, but don't infringe on my patented high performance mods. Come up with your own. I believe the "pop the trunk lid open" mod is still out there ripe for product development.
