ive never heard of the twister either............. how accurate does anyone think that site is on the dyno? according to that site, the trick flow is under the cobra and the typhoon... i think thats some bs...... tf dont pass them up until like 6k... thats some major bs i think

 

anderson is a big supplier for thr typhoon..but don't buy it there you'll pay more....if you want good power you can find a used truck lower and a edelbrock upper it make good power also..just another option..but do match port whatever you get!
