Running or sitting on jack stands
 

So how are all the power adder Pontiac's doing?

Mine is running good, converter is still to loose, thinking my turbine side is too small for 488" may even check the psi by installing a gauge come spring.

So what's up out there?

Jack stands, engine stand, garage attic full of interior parts. Aligning all body panels fixin hinges etc drill alignment holes for realignment after disassembly.... then start my chassis building. Cost to do just back-half with cage kit is near same as doing 25.4 chassis in same material so might as well do 25.4 chassis instead. May never go that quick but better done now than redo later. I can go basic on motor til I'm ready to go more. So basically build a real strong shortblock and use stockish heads modest turbos. Only building a 406 as I plan for multiple purpose Street/Highway/Strip and drag week sounds like a future plan. Turbos can make up for a bunch of cubes and I can still get fair mpg at 406. twin 72's should more than cover my power needs when ready for better heads. MS-Pro with fuel sensing for gas or E85 is fuel plan regardless.

My Tempest is running, but with only one more race date this year (December 6th). They're running jet cars that day and I'm not sure about track prep. Still working on my tune-up. Made a couple of high seven-second passes last time out, but I think there's a tenth in the tune and another tenth at the starting line with a little more work. The schedule for 2015 isn't out yet, but I've got some off-season work to do: oil change, check compression, new front tires (purchased, but not installed yet). I hope to have it all sorted out by Pontiac Heaven in Phoenix in April.

Blower Pontiac running good. Just upgraded to new front tires, installed some different springs to lower rear of car. Of course, had to buy new rear rims with more offset, so they fit in wheel well. Just waiting on new tires to show up, and will be ready once weather breaks... Hopefully get my 10:40 pass in 2015 in street trim....

No jack stands. If you push it it moves. Engine in mock up and assy.

Up and running here, but winter weather has me out of action due to road salt.:snow:
I do have some winter upgrades planed in the trans department, new 6an lines with the addition of a cooler line relief valve and front pump converter feed restrictor. I went through thrust bearing hell on my turbo ford! it wont happen to my Pontiac. Im also thinking of having my 75mm compressor wheel upgraded to an 80, a local company can do it for $300.

What body are you going to build, any pictures?

How long has your car been running?

Running, but probably converting to jack stands for the winter.

Took out old 1 3/4 6 point bar and installing cage, so I wont have to slow down.
MR-1A Shortblock getting built 4" stroke 4.25 bore.....should be fun, aiming for 1000HP with the F1C.

My Catalina is still by my good friends getting the cage finished up and a chute mount built. Hope to have it ready and driving by April Pontiac Heaven also.

1990 Firebird (Was v6 base model w/aero pkg so it looks like TA) pics locked up in other pc til I get around to replacing power supply. Solid car I picked up minus v6 for $300. Cosmetically needs new nose piece and paint but its near rust free. Interior was a bit rough. Basically a great candidate seein Im goin Pontiac power narrowed Ford 9, big tires etc. Engine is my 59 block.

I'll start a build thread after I get around to fixin pc.

Mine is running good in the driveway! Lol! Haven't driven it yet. Had to do a bunch of wiring....and I hate wiring. By the spring I need to change the gear, work on a cage, and see what the converter does.

It's collecting dust in the garage.. I took it out one month ago to let my neighbours know there's a maniac living close by LOL...

My car is sitting on the car hoist in the air, ready to ROCK & ROLL next year!



GTO George

7 years.:)

Mine is in the neither category. LOL

Then what's up?

Sitting on a hoist, no wonder it's ready to go.

Looks like it will be a beast!!

Have one of both! Turbo wagon is running and newly painted,

The GTO survived norwalk...

but didn't survive the beating I gave it on the street! Time to build a good bottom end.

You did a nice job with setting up those turbos....

What was the failing link with the motor , cast crank??

Thanks! Appears failure started in the factory main caps. Hard to tell if the bolts went first or the caps themselves. It was all used junk I picked up cheap when I was still in school and broke, so not much of a loss. Now I am torn between going the aftermarket block route or building a strong factory block engine. I think I may be the first person to run a set of unported 6x heads on an aftermarket block!

Nice cars Alex.


Stock caps are not known for much strength! Aluminum rods like BME or GRP and splayed bolt steel caps probably would have kept that one together!(certainly longer) Aluminum rods act somewhat like harmonic shock absorbers. Factory N cranks are actually very strong but they are also very hard and more sensitive to harmonics/flex than a forged or billet crank(both are more flexible). Not advocating cast crank over forged or billet, just I am aware of a few cast crank motors well over 1000 hp that didn't break the cast crank or if they did, it wasn't crank failure that caused the crank to end up broke.

Hey Alex, how much of a beating were you giving it? Lol! How much boost were you running? Good looking cars!

Thanks a lot! It sounds and revs like it's gonna be! Should be able to take it for a test drive soon, then post up a little video. I've watched all of your guy's videos probably more than you! Lol!

Cool cars, hate to see the blown up engine, have more pictures of the cars engines?

Getting an aftermarket block is a very good idea for growth....

What year is the gto?

The goat is a 74, I was running close to 20 psi this summer. Previous engine was 406 in^3, unported factory heads, borg warner s360 turbos, ms2 controlling fuel and timing. I am leaning towards an IA2 block and forged crank for the new engine. Below are a few pictured from the build, hopefully they will give some winter motivation!

Haven't been paying attention to the site lately and thought I would check in. My car hasn't been on the jackstands for a long time, but its definitely been negelcted. Took it for a spin last Sat to knock the dust off.

Boost controller is giving a fatal error after powering up for 15-20 minutes. Could only muster 10psi, but it sure reminds me how much fun it is to drive.

The following day temps dropped 40 degrees so its probably done for the winter. Plan to spend some time on a dyno next year after the move. I still haven't ran it with methanol yet...

Cool build Tom, subscribed to your thread on YB.

Whats winter?
Love them monster A bodies.

You're motivating me to twin my 74 Ventura. There aren't that many that I have seen with turbos.

With 20 psi what do you think it was making hp wise?

It's when it cools off enough to touch the steering wheel when you get in the car.:)

Mine is on jack stands, waiting for 455..hopefully it will be running next year..
