Your ETC scaler is now incorrect & a huge change in airflow with the intake espically as the rpm climbs.

So yep you need some tunin'n.

I put a breather on my oil fill and capped off the two areas where the PCV hoses used to attach.




My builder ported my FAST 90 with the heads attached (so they were port matched). The results speak for themselves and to me, the car is an absolute beast.

Yes you can cap it, but you need to swap to an oil cap breather filter. Same function

I think Ike runs the ECS cap/breather, call Chris, they should have this ready to go, standard deal in the FI crowd(unless there is something new?)

The Mamo fix you reference is for the FAST 78mm intake. It had a sharp edge just behind the throttle body that would cause a whistle/squeal at part throttle acceleration. After putting up with it for a year I was thrilled to see Tony's post on how to radius the edge.

However, this isn't going to fix the whistle being described on the newer FAST 90 or 92 intakes. There is more than likely a vacuum leak.

im only at 25* timing and the throttle response and instant torque is wicked, and PULLS WAYY harder all the way to 7000

well worth the money

One of these days you will. Your car pulls well as is. If i had one I would be tempted to paint the Fast intake they look great when painted.

Some nice setups in here - I've got a used 90 on the way to the house plus an LS2 TB that I'll port myself. So what are you guys running for the rubber coupling that attaches the LS2 TB to the cold air intake? I'm running speed density plus my MAF is up by the filter anyways so I just need a rubber "pipe" section to connect the LS2 TB to the Halltech CAI inlet...any ideas?

Sorry for the hijack.

But how do you like those heads? Are they the Lingenfelter CNC Edelbrock #61969 heads? What kind of gains did you get with them. PM me if you want to.

Most guys are running some form of a smooth coupler. I have some question as to whether or not those things can collapse at full throttle. I guess it would primarily depend on their length (the longer length would make it more prone to collapsing).
