SRT8 Ram Air Induction System

[John Hennessey]

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we originally made a similar system and the thing that bothered me about it was know that no matter how well we tried to build a shroud to keep hot air out of the filter, that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

Sounds great so far, my only question is, will there be any issue with possible sucking in any water into the system? This would be a major concern for me and most others. Thanks.

i will guess that the bottom of the filter will be around 16 in. from the ground. so i think you will be fine as long as you dont risk driving through any water that is up to your door sill.

I can't wait to see what this will do, as far as numbers go. I know most folks have said that the Mopar gains 5-8 hp, while others have reported no gain at all. DUBair has developed what looks like a polished version of the Mopar unit, made with better parts and they ( or the seller on ebay ) claims a verifiable dyno of 27hp(21-23rwhp) for the 5.7...........no dyno for the 6.1. Evidently Jetchip did the dyno, but the funny thing is no-one can seem to find it......how conveinient! Sounds like BS to me. I'd be happy with 10hp to be honest.......can't wait to see what yours wiil do.

BTW: is it going to look like the one you had posted when you were developing the SRT500???? That one looked really cool.

its the same tube coming from the throttle body. but now instead of connecting to the filter, it connects to another tube that turns down and goes to the large opening that is under the stock airbox. the filter fits under there where you cant see it. so the appearance will be a big polished tube going to the fender. it will have decend bling but more importantly hopefully give you a bit more bling under your right foot once rolling.

i think 5 rw hp is about all anybody with a 6.1 is going to see with any free flowing air induction system. hood up, hood down, all that does not mean crap while sitting still on the dyno. the real performance for any air induction system will be when the car is moving.

fyi - for every 10 deg change in inlet air temp you can see a 1% change in power. thus the importance of keeping hot air out of your intake tract.

[jconnolly1119]

very cool!!! i can't wait to see it.....and the hp gains that everyone else is claiming just kind of cracks me up.....i mean come on.......if I can get 23rwhp by adding a CAI then we should be able to bolt on about 75rwhp by adding a cat-back, right???? ..............i'd just love to see these companies actually show me a dyno at all. K&N seems to be the only one I've seen, but hell.......I could draw some curves on a graph and post them right here from my own computer.......and no-one would ever know. Keep us posted on your design though.......it sounds like you're the only one trying to actually pull the air from OUTSIDE the engine compartment.


BTW: i was kidding about the cat-back hp gains.....just a joke folks!!!

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"!!!!!!

John-

Its refreshing to see someone a manufacturer talk honestly about an intake and the real world results. You guys are doing some interesting things for the LX platform. I feel I may have judged you prematurely...

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?
