IMO Stay away from RA Seals. They eat housings, imagine how fast they would eat a 9000rpm motor. Also, you want lighter seals not heavier.

i will be spraying 175 shot this year on the carbon seals,it has been succesful on a friends car,it's all in the tuning,is 14 sec the best you have done ?.i would like to compare set ups to see what you have different that mine,my car has gone 12.7@110,i'm just curious as to why the big gap in both E.T.,and mph,i would like to see your car n the 12's as well.

If you are not an expert on tunning then don't run nos or turbo on carbon apex seals. You will blow them. I can't believe pportnosgsl friend is running 175 shot on carbon seals. He must be an awesome tuner to pull that off.

the fuel injection will make tuning a lot easier,my buddies car just had a 51 mil weber,the timing is the key to the success of engine survival with nitrous.

Yeah, a good rule of thumb is to retard 1 degree of timing for every 25 horsepower NOS shot. Man, but carbon seals and NOS don't mix well. The very slightest detonation under the bottle will blow those seals like nothing.

i am going to be taking 3 degrees for every 50 hp,i have also clearanced the engine for that specific purpose,and have also done extensive modification to it to make sure it stays together,the engine lasted 9 years before i took it apart for the freshen up last year.

OK quick update Just went and looked at the exhuast Hell yea. Old RE dual flange header cut and new 3in flange installed with 3in all the way back NO muffler yet ordered it 2 weeks ago and still not here. The shop went ahead and for fitment took 3in al the way out the back. Looks crazy with this big 3in tail pipe sticking out. Also had the egt and os bungs installed. I ll post pics when I get it back. FYI the re system just hangs way to low anyone else have that problem with there's?

This was some of the first true step to getting the car ready for the p-port. Next fuel. Did anyone upgrade there lines or just run the stock ones? I am leading to the holley blue or black. More to the black for the money.
