1989 Trans Am Firebird Bullet Grey

• TPI350
• Cold Air Induction with K&N Filter
• 1600 Brutus AMP Powering two 10" 700w Audiobahn subs
• ECU Speed Chip

Built the induction kit out of PVC seihner pipe eliminating excess metal heat. In the works for a ram air kit and hood on top of a 383 stroker 500hp

 

were you at? lol you looke like your in fresno area or even.. hanford/lemmore/ area.. nice looking 'bird there

 

nice ride

what is lpt?

where abouts are you located?

and welcome to the crew


my name is eric

 

Welcome. Where ya located?
Looks freshly painted, and oddly familiar.

 

hello del #2, my name is traviZ

 

welcome to TGO

enjoy your stay

 

did i read that wrong or is he claiming 500hp from his 383?

 

whats an LPT1

 

whats wrong with 500hp from 383's?

btw i think his 383 500hp motor is a future mod once i read a little bit closer.

 

I think all the "boom boom" in the trunk took 50hp off on your Desktop Dyno'd LPT1

 

haha good one, I was a little tweaked out when I posted this so reguards to the lpt1 joke, widely known as a TPI

 

Firebreed, thanks for the compliment. I'm in the Antelope Valley, Lancaster next to Palmdale

 

383 Stroker 500

Horsepower: 500 @ 5,700 RPM
Torque: 491 @ 4,600 RPM
Max. Rec. RPM: 6,500 RPM

 

I believe the cowl hood below would give enough clearence for the room needed for the Holley 4150 750 cfm carb & Proform 14" a/c

or any of these:

 

Nothing is wrong with is wrong w/ 500hp out of a 383... unless of course it has LPT1~~ errrr TPI sitting on top.

I guess he's planning to ditch the FI.

 

i know my motor is 500hp capable, can my fi tuning get up to par? time will say.

 

I'm fairly certain the Stealth Ram would support that kind of power. As for the engine itself, get the proper induction/tune and 500HP is a GO...

I don't know why time & time again people doubt this number.

 

wouldnt what u said mean the stelath is proper induction?

the tooning will be the hard part

 

Yeah. For something that intense, I'd save a load of time running some real-time PROM simulator software.

 

HSR > Stupid Ram + all others.

Any cowl would fit nice, but what about a drop base air cleaner with your stock hood, I always liked the stock GTA hood.

BTW, spiritinblack, are you a SlayeR fan?

 

I'm not doubting 500hp from a 383 or any other bottom end for that matter. The limiting factor would have been the stock LTR induction... hence the initial question. Show me ANY NA SBC running TPI making 500hp and I'll happily give you your cheeseburger.

Travis - I bet you can make some serious #'s running the HSR as it will allow your 383 to BREATHE up into the 6k rpm range. That's where you'll find your #'s... something that TPI absolutely will not support.

Vin - Until HSR comes w/ a CARB cert., I'm moving forward w/ my SR...

 

hsr will never be carb certified, theirs no place for egr

 

I remeber there being some talk about releasing a version that was CARB cert'd. Prolly not enough market like many things for the 3rd gens.

 

there are a few tpi setups running 500hp. they're all boosted though. check out the tpi and power adder sections, the guys pushing that much hp out of tpis hang around here sometimes.

the reason you never see an ltr setup running that much hp is because everyone that has the knowledge to make a motor that powerful knows enough to dump the tpi. but that doesn't mean you can't do it.
