I think you have too much injector, but as long as you can tune them back to where its not flooding the motor then you of course will be fine.

[Joseph Upson]

Good job, but can you do a shorter video at a higher quality? The optimizing has really taken its toll on the sound quality of the engine, it sounds like there is a knocking noise up near the engine.

[Scott_68B]

Great work, looks like it could be a beast. What ECU are you using?

[Superdave]

the knocking sound was the header leaking at the head, that's fixed now.



I'm running a stock '7730 with a chip adjusted to run my #36 injectors. I'll be doing LOTS of tuning after i get the exhaust built and installed



I'll have a better vid tomorrow, i tried to get one tonight but the damn thing is too loud.. and my neighbors looked pissed

Yo Dave, what's the duration @.050 on that thumper?

[Superdave]

here is the cam card...

No heater? I guess it is a summer only car LOL.

[RedBird]

i wouldn't want to attempt to try and drive that thing in the snow. hell, 5 speed 3400 swaps are a bitch in the rain lmao.... and this thing is WAY built!

Next vid needs to be of it moving, Dave...

[Superdave]

here is a distant clip after i installed the muffler.. there is no tailpipe after it so it's still pretty loud...

[torq455]

what rpm is that thing idling at? almost sounds like it's pretty lopey.

[IsaacHayes]

IIRC he has it down to 1000rpm now.

[Superdave]

that's with most of the exhaust hooked up idling at around 1K RPM.

MAP is averaging .75, Moonwell says that's around 7.4 hg of vacuum. I'm gonna go buy a vacuum gauge and find out for sure..

It's almost ready to take for a drive.. just need to finish up the exhaust and install new sway bar bushings.

[RedBird]

Haha. those bushings were slightly shot....

and f' the neighbors. if they can do that, you can drive your damn car up and down the street open headers at least once :P

[IsaacHayes]

lol, 7.4hg of vacuum. I've got a pretty cool "turbopac" vacuum gauge I got for like 12 shipped on ebay brand new. It does a half sweep from 20" to 0" and past that it can go to 4.9 psi of boost.

EDIT: This one I have. I think the industrial liquidators is the place I got it from. They were selling them individually for a while I think. Might of been someone else though that had a bunch for sale.
