When will it run out of air with this new setup?

------------------
89 FORMULA 350 Edelbrock base, AS&M LTR's, 52mm TB ,Edelbrock Cat-Back March Pulleys
Accel Cap ,Super Coil SLP Airfoil K&N Filter 180 stat , Fan Switch
Taylor 8mm Spiral Pro,TB Bypass ,Energy Sus bushings ,Hotchkis STB ,MSD 6AL ,Edelbrock TES's ,Hi Flo Cat ,Crane AFPR ,Shiftkit w/Hurst lockup

 

redline will be the same. it will pull harder in the uppers though

 

Well you could change your redline however, I wouldn't do it. Your regular TPI 350 redlines at about 5500 rpm however, the car quits developing power at about 4700-4800 rpm. Your breathing will be much more effective from 4500 to 5500 with the new intake system but if you go over 5500 you will run into the same problems the factory system had at around 4700 or so rpm. Keep the redline at 5500.

Through experience...

A stock runnered L98 will make peak HP typically right around 4400 rpm, thus shifts right around 4600 rpm were best for your et slip.

With aftermarket runners wtih the stock cam, typically your rpm peak only goes up 1-2 hundred, however with a matching more agressive cam, your peak HP will typically occur between 4700-4800 rpm thus your shift points should be in the low 5000 rpm.

Hope this helps
