Ok well a little update from my end. I put some TR6's in the car on friday after work. Car ran really good with them and didnt feel like that had that miss up top. But now I got a bigger problem. I think I might have lifted a head on the car. I had coolant splash on the windshield from the radiator cap I am going to try a couple things to try and make sure thats it. If so I will be pulling the motor asap putting new head gaskets in and putting it back in the car. If I have to pull the motor I will look at my money situation and see if I cant do cams at the same time. Im not sure if I can make it happen or not though. I will keep you guys posted.
I have a built 5.0L stroker with all ARP everything even ARP head studs. I have aftermarket head gaskets. If I remember right, they are FEL-PRO. They are what MMR suggested for my boost and plans of the car. I am running 23~24 psi boost. Its pulled for around 30 psi. Its hits 30 psi then its starts to slip and comes down to 23 or so really quickly. The coolant only starts to come out under full boost. It doesnt smoke at start up. It doesnt seem to be burning any coolant. Just under full boost it seems to pressurize the coolant system and shoot some out of the cap. Which is what leads me to think the heads were lifted.
I was thinking that tr6 was stock range for the 03/04 Cobra ??, any way , when I was running e85 I started with the BR7efs and the car ran like garbage ( it was 40-50 degrees though) swapped to TR6 and it made a major improvement and the car idles and ran much smoother, went to TR55 and car felt much stronger.

Jake now that were on the subject again you should look into the R5724-8 plug by NGK (stock # 7317), looks dead up like a tr6, just isnt as projected. I had a set but never did get a chance to equally size them up due to some issues at the time Could be the the ticket......alot of the lsx guys use them who are loyal to tr6's when the are on the sauce, claim next step cooler from tr6.

I may order a set up, my car is safe on 6's and 7's, but it would be really nice to find a plug that negated my 20whp loss and maintain some extra safety.....you will see the track before me again, not hitting again unless some killer air comes around or the solid axle shows up. I may get bored and dyno whore it
TR55 the tip is alot more projected.......
Ya Broke that was mainly the reason I was using the BR7EF's just for a little bit of safety, so I wonder if those #7317's are any good with the projected tip..... Be nice to have a good plug for max power potential and a little safety zone to....
