New dyno results for NA 306

86Cobra · 11-17-2004

I've been fighting valve float for a year or so now and finally somewhat tamed it with much stiffer springs (160/410) and titanium retainers. Now it pulls strong to about 6400. It used to float the valves around 5800. Hopefully this will translate into better track results. I had it at the track this past weekend but my clutch gave out on the first launch.

Motor is a 10.8:1 306 with TEA ported TWs, FTI cam, and a Holley intake.

That's a ton of power! Especially from a N/A car. Why did you go with a holley intake and twisted wedge heads ?

Yeah, if only my vert wasn't such a fat pig. Race weight is 3250 even though I've pulled a lot of weight out of it.

I've had the TFS heads for about 8 years. When I got more serious with the car a few years ago I decided to keep them and have them ported. I picked the Holley intake because it's the one all of the NMRA Pure Streeters (10 second NA 306s) use.

wow, thats some power. i hope i can get at least 350hp to the wheels on mine. but i still have the stock tranny.

Holy crap, that is unreal power for a NA 306. Now all you need is a turbo kit and you'll be well over 500 at the wheels lol

So whats it run

Not turbo kit with 10.8:1 compression.

I'll have a new clutch in it in a couple of weeks so hopefully I'll be back to track in December sometime. It should be a little faster than before so I'm hoping for 11.6s at 117+.
