He mind as well switch to an S or A Trim Head Unit. He'd be alot better off with that combination. Plus that header heat is killing him being sucked straight in an already super hot head unit. Especially with no aftercooler and out on the street during brutal days of drag week. Definitely needs a power pipe or something custom to the cowl if he retains that setup! That pro volute is for front facing hole through the bumper or exposed head units on race cars. Besides that that is a bad ass car! Street cars like that is what it's about!
@@tomsettles6873 definitely, I've seen the difference that causes on a dyno. Having the headers jet hot coated helped but you really want a power pipe to the fender well or going up to cowl area. Not to mention that this is a real street car and being older it doesn't have a engine shield or splash guard. Even the tiniest pebble, dust and dirt is not good for that impeller at all! Many years ago my buddy switch from an S Trim head unit to a T Trim, without putting the filter on he said "let's go for a few pulls" I said with it open like that! He said sure it's fine! This is when you couldn't get stuff overnight and it took a week to get that head unit. Well on the second pull a short piece of stick got sucked into the opening and F'ED up the blades bad. We live in Delaware, so the head unit had to be shipped back to California, repaired and sent back. Took a good 3 weeks. I remember the Vortech rep saying it was good it was a rock or something harder then the stick, because they only had to replace the impeller. The rep said a rock or anything like that most likely would have scarred the housing and most likely ruined the head unit!. Around the same time (1998) I had a Procharger (when hardly no one ran ATI) D1 on my car. I was getting around 22 psi of boost, I was running 10.05 but no matter what I did I couldn't get in the 9s. Running 9s then was dam near impossible with a street car. I got my hands on a cog pulley setup that I had no right putting on that D1. But I said it's just for 1 run. Well during my burnout I overspun the blower so bad the impeller flexed out, cut into the housing and broke into ALOT of pieces. The ONLY thing that saved me was my Procharger was aftercooler and the aftercooler caught all the pieces of impeller that came apart. I recently put in a A4 block that I has about 20 grand into. I have nightmares of what them impeller pieces would have done if the aftercooler wasn't there and they went into the intake! I'm not a genius or anything. I'm just a guy that's learned the hard way. So hopefully I can spare someone else the agony. Take care and thank you for your comment.
blow through carbs dont need intercoolers the carb does the cooling thats the cool thing about them no pun intended... and that's a big engine the YSI is doing what it needs to do. almost 800 at the wheels is a lot on a poncho
Car is totally cool except (literally) for the air inlet for the blower directly next to s header? That is a H(hot)AI if I have ever seen one! This has to result in some really elevated IAT’s when the hood is closed. Would think routing the air inlet towards the front of the car would make a significant assist in tuning and power?
when you're voting this year make sure you do one choice of voting make sure you vote Steve Morris as president of the United States cuz he will make sure everybody has a good engine in their car or truck
Wasn’t this car run with a stick in prior Drag Week events? When did the owner convert it over to auto? Looks like the clutch pedal is still place? Presume the owner is looking for less maintenance which is understandable.
Good it's nice for a change ,. Pontiac always received a bum rap why they never unleashed the real power , we ran a 421 bumped it to a 428, in a firebird.from the aluminum front end Catalina.
If they'd had unleashed pontiac, there would had been very few chevelles novas camaros etc. Sold I believe so they seen pontiac about to pounder so some1 got scared and went crying to GM leaders and had pontiac ended, atleast that's what I'm thinking from my view and research, (tho I wasn't old enough around and I also was also probably crying over spilled milk and gummybears, well wait maby milk and cookies spilled) back then to remember

Why add a blower and keep boost so low? There are turbo honda 4 cylinders making same power. If he has an aftermarket IA block I would be at 12 lbs of boost minimum. And turn it up to 15-18 on drag day. 1200 HP easy. Pontiac guys play it too conservatively. Turn that mother up!!
And those Hondas are almost coming unglued at way higher boost too. Spinning ridiculous RPM. This 474 stroker probably doesn't spin past 6000-6200 most of the time. Like he said the time of this video they're not even spinning the blower that fast and it's making almost 800 at the crank!
One of my favorite cars of all times! One year only, which I just never understood. My dad had a 68 Lemans 350 3 speed.
Pontiac all the way !!!
Bad ass. Great looking car. I love the interior colors too, its very similar to the interior colors in a 68 Fairlane fastback I used to own.
Cool. Love those 64-67 mid-sized Pontiacs!
Beautiful car!
Pontiac🥰❤️
Nice Pontiac
Very cool, I learned to drive on a 64' "Bronze Lemans" and this brings back memories though that straight-six didn't have this HP!
Love it! I would take the GTO emblems off the grill, however. Keep it a Tempest!
Definitely get rid of that lame ass Superchargered emblem
Yessir leave it Tempest and keep em guessing
Reading the commits someone said this car has possibly drove Drag week ,any ideal how fast it was? Killer little Pontiac
Beautiful car a really cool set up Steve thanks for sharing it with his buddy
Why does the valve cover say LS?

First thing I thought also was header heat getting sucked in. That has to be costing 50-100hp on the big end of 1/4 mile.

11th👍's up Steve thanks for taking us all along with you for the great show of power

Hoover the Groover ! Hope to see you again at Drag Week ! Steve will get you squared away...
Who won?
yessir very nice ride and smooth power for cross country cruising
Wow super beau set up les boys 👍🏻
Hp NA L = 728,55 /(1,568 MAP x 7,767L ) = 59.82 hp / L
lb/ft NA L = 661,76 /(1,419 MAP x 7,767 L) = 60.04 lb/ft / L.
I was so close. I said 701hp 665tq. Someone lower was closer. On the hp way off on the torque.
Who won? What are the final numbers?
No intercooler and pump gas? Nice.
What does it make on engine only?
I was also wanduring the same
2:17 It tried to fly away
The only way that car could be cooler, is if it had my name on the title.
Oh man love it!!!
ahh i was close, 724@705 🤦🏻♂️ lol
I guessed 713@690 pretty close I guess.
Good it's nice for a change ,. Pontiac always received a bum rap why they never unleashed the real power , we ran a 421 bumped it to a 428, in a firebird.from the aluminum front end Catalina.
My grandpa still drag races an aluminum nose SD Catalina

No intercooler. Depending on fuel octane & compression ratio, can't go much more than that.
@@R0yL33 Yep. need to add an intercooler. The IA block can take up to 25 lbs of boost. Big Chief runs that or more.
Tom settles - Big Chiefs engine almost certainly has concrete filled water jackets so that isn’t an apples to apples comparison.
I see this car around town alot .he drives this on the street alot .its bad .
And those Hondas are almost coming unglued at way higher boost too. Spinning ridiculous RPM. This 474 stroker probably doesn't spin past 6000-6200 most of the time. Like he said the time of this video they're not even spinning the blower that fast and it's making almost 800 at the crank!
728hp and 661tq not bad
Just keeping it real!!!!💪
Wow nice
Needs cold air intake.
LMAO that volute makes way more power than a cai yo.
