one slow twin turbo 94 cobra??

I have a 94 cobra, twin turbo meth injected, the turbos are i think 37 mm,i has a 306 with aftermarket heads and a cam and upper and lower intake,it has a viper 6 speed with a 3.73 gear,and also has 305/35/18 Nitto 555r drag radials, had it to the track and best i could get was a 13.38,very slow(least i think)for all the stuff done to the motor,any advice?????????????  

What was the MPH? Yes, that is slow, but a car's MPH is a byproduct of horsepower. And maybe it's just me, but it sounds like your turbos are pretty small. Have you had the car Dyno-tuned? If so, what kind of power did it make?

My first run i was at 102, my second run i was at 105, thats when i got the 13.38, the car has twin 37mm turbos,it has blow off valves and it is a cammed motor with heads, aslo it has the methanal injection system. I think I should of not warmed up in the water box and also should of left the line in boost????  

Something is definitely amiss. I would invest in some dyno time because there's definitely something wrong with this picture. I still stand by the fact that you're running small turbos; even a H/C/I/ 94 Cobra will run low 13s at 105 mph. How much boost are you running? You want to keep the engine cool right before you run, and you also want to have at least a few pounds of boost at launch, but I think there are other variables at play here.

I agree that the turbos are too small.  A 37mm turbo will only support about 150hp.  So your twins can only support around 300hp.
