taps do you know your base HP if not what compression are you running.
|
dont know hp,running ross flat top blower piston,about 7.5 to 8 to 1

taps you have to understand that this is just a guess and I am a bit conservative with the numbers because of the amount of variables in this. But going by the info that you gave I am going to have to say around a 5.90/5.80 ET & MPH 115/118 thats if you get the boost you show. Well be sure to let us know what it runs after your pass. And make sure you have all your safety stuff to go with a number like that.

Another thing to consider, blown gas cars love intercoolers.

Could be you're right,
right now the big rod show is going on over her in Gulf Port, it's a week long show. there's a 68 chev truck with a 1071 blower on gas that the guy is driving around. He said before he put a 4"tall intercooler on the truck he couldn't drive it at all. He said with the intercooler it dyno'ed at 1000 HP and it's totally streetable with the big blk. He also said he only ran it 1 time and it didn't hook until 1/2 track on wide mickey street tires, it only ran low 11's but at 140MPH. They wouldn't let him run it again because he didn't have a full cage. it was just a thought. Zip. |
