There is much debate over the manifolds, whether they be log or tubular....
We have obviously proved that a log style can make big power, and others have done so with the tubular design.
The manifold that AGP sent me was ported and cleaned up some. Did this help spool time? Not sure but I do believe it played a role in the high hp numbers my car got, because at that point in time, those numbers were amongst the highest hp numbers made on a SRT, now, many are making big power.
A 50 trim spools pretty darn fast considering its a bigger turbo then the stock (dare I say it) toy hairdryer.
If I put a log style manifold on would the performance have been better?
I don't know and can't rule it out, I can only say, AGP did their homework, and we have made tremendous power with the log style, and it hasn't cracked, atleast not yet.
My car trapped 125 when the DA was 6500ft with this manifold, I have argued that this car would trap 127 - 128 at Sea Level and a track that is properly maintained. The cars ET was only a 11.85, due to a poorly prep track, and not the best driving skill which led to subpar 60ft times.
But on the street the HP was there. The RED car literally slams you into the seat, one passenger said they thought they got punched in the chest, another said it felt like a Runaway Semi Truck hit us from behind.
This car on the streets of Albuquerque regulary made Vettes, Vipers, LS1's, look stupid, because I didn't just eek out wins, rather 'The rout was on baby!'
The torque steer is tremendous and quite thrilling actually. And yet this car was suffering some due to the altitude conditions of Albuquerque, which unlike Denver, Albuquerque is a mile high desert, making it somewhat unique.
Because on top of being 5300ft up, we regularly see temps of 104, 105 in the summer, pushing the air density as high as 9000ft....
And for whomever doesn't believe that this type of air hurts the performance of your car, then please kindly drive up a Mountain and see if its perfomance doesn't suffer....
So again, the AGP log manifold works. This isn't to say that the tubular manifolds don't or are not better, I really don't know, but rest assured,
had I of given you a ride in the RED SRT, the last thing on your mind would be
what kind of manifold I am using..
