I would really like to see 400rwhp...really. But 380rwhp would still be quite nice, especially if peaking at 6100 like you suggested.

i dont think it will happen thru the stock air box/MAF. This car really feels sluggish at high rpms, as its trying to get air and i'm thinking i'm just restricting the hell out of it

i gotta order a battery relocation kit and get a custom CAI in there

Is your MAF descreened or is it totally stock?

descreened but even then its suppose to flow like 700 cfm. i dont think thats enough considering my TB flows 1000. I think this motor wants more air so i'm eventualy gonna build a 3.5" air intake system and custom 3.5" maf sensor using stock internals and 3.5" tubing like DOC has done here on this site

else maybe buy a bigger MAF that will work and/or translator if necessary. I'm not sure yet

i'm gonna go play with WOT tuning tonight and see if anything improves, then hit the track tomorrow night to see how it runs. Going by feel i think this car will be mid high 12's at 110 or so. maybe even slower haha it doesnt feel that great at all so far

Ahh yes, the "Mega MAF." While cheaper, I like the idea of using a factory replacable MAF (better parts supply) and a translator, but I don't know the total cost on that either.

I'm glad we'll get to see how this ported HSR runs on a good flowing motor with the stock MAF though.

I've seen some pretty fast cars that still run a stck size MAF. If you go to the link on my web page, you will see info about my Buddies Vette. Bowtye8. He went low 11's on motor (383) with a stock size MAF.

Both of us run aggressive ignition timing 37-38 degrees total. You may want to play with that.

Good luck at the track!

heading out now... i dont expect to be fast since its 86 degrees but we'll see. I hope to get it close to dialed in WOT tuning wise

car feels like mid high 12's tho

^ Haha, you sound just like me w/the SOTP feel lol. Good luck bro....

Sounds like we might get some initial dyno results soon.

results are in, i'm making a thread and uploading vid of 2 of 3 run tonight. I'll link to it here in a minute

Hmm, you didn't let us know just yet. I'll go out on a limb and say that if you had anywhere near a 1.70 sixty foot, you were in the 11's (yes, I believe in Bret Bauer)....

good guess

+1 for Bret Bauer cam i guess... cant wait to see what it does with proper gear, proper launch, proper tune and good weather

Congrats!

dyno'd the motor

best i got was 392 at 6250 rpm but the motor was running very hot at 205 degrees on that run

best torque was 371 at 4000 on a different run but no changes were made to the midrange numbers on the last run which made the higher hp. but its over 350 from like 3700-5000 rpms. Very very flat. Heat probly killed torque on the last run

Not bad but i really do believe the stock TPI intake/MAF setup is hurting it

See thread
http://www.thirdgen.org/techboard/al...got-383-a.html (So I got the 383 HSR dyno'd. Good and Bad inside)

i have a 406 10.1 comp 5.7 rods 215 dart heads cam solid roller 242 248 668 lift 19--43-- 54--14 was wondering if someone would run it for me on the dynosym

YOu shouldnt revive old threads like this for questions like that. But i know a guy with a similar motor that has ran high 10's at 126mph in a street 87 trans am. Thats 450-475 ish rwhp

well i needed the torque numbers more so then hp numbers
