Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

I LOVE quirky late 70's/early 80's rides... that thing is all kinds of choice!

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

i think im going to take it out for a cruise tomorrow

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

what boost are you goin to be running? I think your mid 12's is way conservative....my 4100 lbs typhoon went 12.6 on18psi with a WAYWAYWAY smaller turbo....Lovr this thing get it to the track with some video ASAP

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

i want to turn it up to 10 psi for now. this motor is a true 11.0 CR. the e85 is good but i dont think it could take too much more than that. ill probably blow it up seeing how far it will go

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

Gus looks awesome,
glad the filter worked out for you also,
keep the pics and updates coming,
dont put a cowl on the hood leave it the way it is,
you definately have a lot of power left in that combo

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

thanks carmine.. yeah its for sure not getting the cowl anytime soon. the look on peoples faces when i drive by is priceless.. they hear the weird exhaust note that grabs their attention. then they see the bonnet and are like WTF?? whats wrong with that car?

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

i bet it'll be really responsive and spool great with 11.0:1 comp. and e85. cant wait for a drag pass video.

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

ill agree with that

yep, id be suprised if that thing dont go real low 11s with under 10lbs of boost


ive been running mine open down pipe all summer long. the 4.3s have a very distinctive shound

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

theres a little dragstrip program called dragstrip plus ive always played with. it is spot on with my older NA projects. no matter how i plug in this turbo project it comes back on 10psi like 430-440 RWHP and low 7's@almost 100mph. feeling just the 5psi the other day i think it can do it. the car is light. i dont how light but id be really suprized if it were 3k with me and gas

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

sold my POS innovate lc1 and installed tonite a AEM uego meter. ill i can say is wow. big difference in quality and install needs. much much simpler and a better product as far as im concerned. good deal on the AEM with VSracing too!

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

well got my carb back from carb shop and the car is a widowmaker now.. lol sideways out of control in 1st and second.. i didnt get to run it out so i dont know what the top end's like. anyway got my seat belt harnesses in and finishing up the carpet now. should have some interior pics tomorrow night. and i have a dyno appt. sat morning at 9am. im only getting a couple pulls cause its a buddy deal and before the shop opens.. the WG spring is a 5psi and that exactly what i saw the one and only time ive gotten to look at it. wish me luck on the rollers. it made like 258somthing NA 7 yrs ago. its only gotten fresh valve springs and the BW s400!!! :hmm: :noidea:

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

This is a cool build. I'm glad I came poking aroundin the builds board today. Keep us updated on those roller numbers.

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

Good luck!!!

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

excuse the filth.. the car is waay too dirty! im going to get the detail boys at work to buff the whole car soon

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

i love your car dude. that thing is cool as hell. your car emulates the build style i want to build my bro's gremlin x with. clean and simple. good parts. you have to get us some video of you goofin around in that thing.

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

Hey, you're missing a headlight!

Man that thing looks awesome. Let's see some fun videos.

 

Re: 1980 pontiac sunbird (monza) 4.3 V6 75mm S400SX

well i got some carb issues worked out and upped the timing. for the 1st time ive actually got good WOT numbers and i made a full throttle 2-3 pull. THIS THING IS FAST!!!!!!!!!!!!!! not fast like around this site, but for a lil guy like me its ballistic! ive rode in a 550rwhp/590rwtq fox turbo car that ran some 9.90 136 passes and its not there yet but the "seat of the pants" is very similiar. i had to get out of it cause full boost (whatever it is right now) in the top of 2nd BOILS the hides and keeps spinning into 3rd as far as i want to go! granted im on regular radials (235/60/15). at this point im 29total locked out, should be 5psi (was the one time ive gotten to look at it) and 11.2-6 WOT AFR. so im at least safe now to look at the boost and fuel pressure. 2years of hard work JUST PAID IN FULL TODAY. thank you to everyone on here!! TTF.com is the only website. i need tires!!!!!!!!!!!!!!!!!!!
