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we originally made a similar system and the thing that bothered me about it was know that no matter how well we tried to build a shroud to keep hot air out of the filter, that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

right now our target price to eveveryone is $350 plus shipping. we make about 100 bucks on that. the carbon fiber will likely be more. wont make any excuses for the price. just want to make the best performing part possible.

a little over 3 bills for the mopar and almost no gain except for throttle resp.

a little over 4 bills for the DUB, which looks like the mopar but with more bling...........

or right down the middle for yours, which judging by your rep. for building Viper parts, should look great and provide increased hp and throttle response????? where do I sign up.?????? this seems like a no-brainer

can't wait to see the pics :banana:

if you take off your stock airbox you will see a hole directly under it where fresh air goes into the stock airbox. that is the hole where we put the filter. this area was designed to give cooler, pressurized air to the stock air induction system. pics coming in a few days.
On the SRT-8 "C" the air doesn't really get pressurized below the air box. I have a feeling it's the same on the Magnum.

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???? :biggrin: ..............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 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!!!
I totally agree,and it makes me wonder what the charger srt-8 is going to make with its functional hood scoop to let fresh cool air in as well as extract hot air out! HMMmmm....interesting.....John...any ideas on this theory or you think nothing noticable?!
Any numbers yet??? :drive:

BTW - The MF system rocks. Thanks!
Any updates on this????

the pipes come back from the polisher tomorrow. hopefully we will have some pics up as soon as we get them. will begin some accel testing on a stock 300 srt8 with this kit. 0-120 mph before and after or something long those lines.
im excited to see the pics :banana:
