Well guys,my question is,did you feel a big difference swapping the j-tubes to the bigger 90mm?im thinking on getting one if they help much in power.now i dont think mine is a 90mm,its a 112 on my 08'4.8.
no wonder if magnuson has actually dynoed the difference.

 

Im sure he will be in here sooner or later but pm blownchevy, he can answer any of ur questions, he is the radix guy on here.

 

yuphim,or i should've gave joe a callRight now im after every little power(bolt-on)out there for my truck.i got a big street race call out and i need all thehelp i can get.

 

weight reduction and nitrous

 

i got some weight reduction out ofthe way,like center seat,jack,spear,bumper for rollpan.im at 4520 with me in it.what else could i do,and i dont think ill run nitrous maybe meth.

 

some say the 90mm adds 35hp. I did the swap with a few other things so cannot tell you how much i gained. I think its a worth while mod expecially if trying to squeek every single hp.

 

The 90mm alone is probably worth a little hp like Bill says but if you combine that with meth, injectors, ect I think it just eliminates the bottleneck effect in your system. Sooner or latter it is going to need more air to make more power.

 

cool,good to know,thanks guys,ill have to get a hold of joe to get pricing on one.
