You can see the difference if you look at the pictures closely.We were not going to offer these but do to the steady calls and request for a collier that will not defeat the purpose of the 90mm intake and throttle body here it is.The opening of the collar is the same size as the 90 mm. body. So you can use the same size hose that you have now for the throttle body. No need to purchase largeer or smaller hoses. Buy a collar and that is it.They sell for 175.00





This was desighned to work with or with out nitrous.It is a true 90mm so the induction passage is not choking down the air flow

that looks great, good job guys

 

Sorry HPE, Nitro Dave and his partner did it right the first time! Good job guys!

 

Dave, you may be getting a call in a few days for two of these.

 

sent you a PM!!!
I need one ASAP

I assume they have holes for duel nozzels? What nozzles to you recommend for them?

Are they ready now?

 

sweet!!

 

Mean thanks for the call.It will be your way shortly.
Dave

 

Damn, that's a nice piece, and I still need something like that.
But $175 for a piece with no electronics or precision parts is pushing a little past my remaining budget after getting that dual stage kit last week I guess I'm gonna have to get inventive some how....

Anyway, great job and thanks for stepping up to the plate with another fine product
