I got a reply from Speed Inc. with my RGR stage 2 Heads;

100-600 flow numbers

INTAKE EXHUAST

68.2 57.1
145.7 118.5
203.2 161.5
251.6 203.6
287.6 219.3
293.7 224.3


I haven't looked at enough flow charts to see how I did comparatively. Your input is appreciated.

They look very respectable to me man....down low and mid rage they out flow a few company's head's..(not gunna mention names) but yep I am sure you will be happy. Nice work Speed inc. & RGR.

velocity is important too, and every flow bench is a bit different.

Your best bet is to test em on the dyno and the track.

Verbs hit the nail on the head, the key is

(Flow) / (Runner volume)
300 cfm / 225cc runner = 1.33 cfm per cc
300 cfm / 205cc runner = 1.46 cfm per cc

Thanks, I'm encouraged. This was a factory strong car too, so I 'm hoping for good numbers. On 11/14, I will be tuning it-the deluxe plan, in Tampa. Florida is a "low dyno" state because of heat and humidity, but by then it should be cool for some decent figures.

As far as the track times, that will depend on how long my stock 10 bolt with 4.10s holds out. Nitto DRs are on deck next 'cause I'm breaking loose very easily right now.

Time to sign up for that law-away 12 Bolt purchase...

Jeremy Formato at www.fasterproms.com. I got some great references from his work. I would be happy with 15-20 more HP from this set up.

I can't wait. Head/Cams are funner than ****.
