Went to run Ozark International Raceway with Chin weekend before Memorial Day Weekend....

HOLY SHIT that track is KILLER.

Ended up running a 3:10, but the car has a ton of time in it.

4th session on day 1 the car started missing so came off track. Swapped all ignition shit off my buddies car onto mine, still missing. He said "I had the same issue when the little filters off my injectors were clogged"... pulled them off Sunday morning and sure as shit, clogged. Knocked them out and ran the final 2 session in the afternoon. Car has time left in it, 8-10 seconds at least probably more.

The video's dont do Ozark justice to the elevation change. Everything is blind due to hills or turns.

Here's my 3:10 video.

Lit 'er off for a few seconds this morning AND IT'S WAY LOUDER THAN I REMEMBER. It was at this point I realized that the header intermediate pipe clamps weren't installed

The next step will be the multi-day process of filling and bleeding the intercooler loop. It's probably time to get a proper reservoir because this game of tricking in a few ounces into that stupid T-fitting is no fun.

I also found that the coolant overflow bottle developed a crack. Spent a few minutes trying to figure out what hose clamp got overlooked before realizing the source.

Damn that is full up.

New Green belt , we have a good run with them.

Normally just use a cheap 20litre/4.5gallon fuel cell in the boot/trunk for a reservoir(ice box) with a 2in thick sheet of fuel cell foam in the bottom to stop the ice from blocking the outlet to the pump.
Also have a ball valve to drain the excess water so you can dump a bag of ice in for those times you want to lower the intake temps for a short burst.

The racecar remix nears completion.

This is the ongoing saga of Going from the "HoOdRaT" 6.0 to a more purpose-built 427. Some of this is redundant, but I added some pieces and machine work over the last couple weeks.

Recap on parts:

• New Dart LS Next tall deck block
• Callies UB 4.013" stroke 8 weight crankshaft (more on the weird stroke here in a sec)
• GRP AL rods
• CID dry deck LS7 type heads (no coolant passages)
• .805" lift solid camshaft I had made
• Jesel .905" solid rollers
• Jesel belt drive for the camshaft
• Jesel shaft rockers
• Peterson 4S dry sump pump
• Peterson 10qt tank
• Some zillion dollar one off pistons for the quench ring and compression setup I'm after
• Wrist pins that look more like impact sockets. (they beefy)
• Billet dry sump pan I made at work
• MSD Pro 600 ignition (think arc welder for a spark plug)
• Aeromotive 12gpm fuel pump (all the methanol)
• 8x Injector Dynamics 2600 injectors (intake tub)
• 8x Billet Atomizer 750lb/hr injectors (blower)
• Manson pushods
• Alky Digger blower to manifold heat exchanger
• Whipple 8.3liter supercharger
• Top Fuel Hoops
• Copper head gaskets
• 1/2" ARP head stud conversion
• 2-1/8" SS Zoomie headers
• Holley EGT sensors
• Holley Dominator ECU
• G Force Engineering Outlaw Axles
• G Force Carbon drive shaft
• G Force Inner/outer Outlaw axle stubs (IRS car)

On the old engine, we dipped into the 1.2s for 60 foots and nailed a 5.23 in the 8th mile on a 275 radial tire. It also cost me an engine, lol. I learned that at 12.5:1 compression, 35psi, and alky, the window becomes quite narrow when you try to fatten up the engine due to a big change in Density Altitude. A 3% bump in fuel locked up #7, bent a rather expensive rod (impressive), and tried like hell to rip the #4 main web out of the block. It split one side to the cam tunnel and was on its way to doing the same on the other. We think that engine was making something at or close to 1500 flywheel.

This new one ought to be in the 2k+ range.



Block in the mill for lifter bore enlargement:

Head stud stuff: Converting to 1/2" diameter.

Cleaning up the casting flash between the lifter valley and timing chain window.



Dry sump pump mount stuff: Take a big block of aluminum and whittle almost all of it away...

Dry sump oil pan...

Op2:



Completed:

Now that all the one-off stuff is made, it heads to the engine builder for the block work. Hoping to have it together by August.

Fingers crossed.

I thought for the most part it wasn't permitted to run a charge cooler/intercooler with methanol? Or does that only apply with turbo setups?

Man that blower is massive. I cant imagine the torque hit on that monster..

It's never been brought up before. Tech inspections have always been a breeze. The "small tire" stuff around here is pretty wild west. Basically, the car has to be certified for the time/speed it can run, and you can't run rubbers wider than 275.

If I weren't allowed to run a cooler, I'd be in trouble, as the blower is an excellent space heater. The first time out, we melted the end off of two IAT sensors. (temps approached 400*F). In an 8th mile, we burn 7 lbs of ice. After a run, the ice tank holds reasonably cold water. My hope is that with the new heads, this will improve. For the last two years, we ran a pair of PRC cathedral ports on this thing. (lol) On their best day, they peak at around 310CFM. The new ones deliver over 100cfm more so boost pressure ought to come down and that'll lower IATs as well.

 

[LRI]

It is quite violent. lol. Taming it requires pulling almost 20* of timing off the hit and ramping it back in over a 1.2-second span.
I think the next thing is to get a different convertor to loosen things up some more. I recently got educated on this. Basically, the new trend is to not rate converters in terms of "flash" or "stall", but blade pitch and count on the stator. The new ones are two pieces that'll pull apart allowing for stators to be changed relatively easily. (vs the traditional way of having to cut them apart, etc..)

Being able to "tune" the converter with out having to send it in does allow you to change things with out getting it back to the manufacture, but you still have to have the stators turbines and pumps to swap out.

Thing is the bolt togethers are extremely expensive and you need to consider if it out weights buying a few "welded" converters to swap around and have on hand for different circumstances, instead of taking one apart and swaping parts. Looser for a no/low prep and tighter for a well prepped track.

Getting the converter to work right with each individual set up and track conditions will take some time. But can shave time once figured. With that 275 tire limit you are likely going to want something pretty loose.

 

[MadDuner]

My only attempt at the track on radials resulted in 2.0 60' times and 12.46@136 mph.
I was wrecking the entire pass but just didn't hit anything.

[softcock]

Was cleaning out a backroom today, tossing box's and bags full of saved old crap in the trash, and found a Pic. of old blast from my past .
It not as nice as some of the other transportation seen posted in here, but it was really a nice around town runner that sounded good when you put your foot in it, and looked nice and clean . My brother also had a few built around-town runners of the GS's 350 and 455's and a OEM matching #'s 71 Stage1 455 GS also .

The Buick's, 68- 72 skylark/GS , GS stage 1 , GSX Stage 1's , 350 ci and 455 ci ..
In The Day, They Were Some SweetAss , All American , White Trash Muscle to own and drive .

Anyway this GS in Pic. I had was all there for OEM parts and I and factory build sheet to go with it . It was not fast, just respectable with 350 horse and 3-speed auto Trany. The big block Buick's were on the heavier side but..' nice smooth ride' . I did not go Buick factory on the Paint and interior . I did it in, 96 Dodge viper metallic blue on body, with white pearl interior .

Makes me miss it.

On a side note, has anyone used those services where they take old format video and convert it. All of my racing stuff is on old 8mm and VHS-C tapes. I would love to watch them again but can't. Those services are tempting, but if I send them the only copy I really worry about it being gone forever.

Well.. Thats a tricky one.

The motor that currently in it is just a mock up LS1. The turbo in the pic isn't mine. The turbo in the pic is smaller than mine. Ive got a 94/102 FIC built Garrett.

I have a built 5.3 short block that i was planning on using but actually decided yesterday with my builder that we're going to sell that 5.3 and possibly go with a built LS3 or 6.0. The goal is 5.1-4.9's in the 8th. Probably around 1050-1200 whp.

I have my level 4.5 TH400 that will go behind the motor. Right now, its getting back halfed so ive got time to figure out the power plant situation. Goal is to have it done and on the track by fall 2024. Still has a long way to go but its a process.

Just going with pump gas I assume? Probably a good decision going with a bit more cubic inches if you're gone be doing 1/8mi stuff with a 94mm turbo to spool that big SOB up a little easier...

 

[BLKWLFK9]

E85. It will probably never see 93 or lower.

 

[BLKWLFK9]

And the 2step/trans brake will take care of spooling the turbo. This turbo actually came off a 5.3. He only went to a smaller 88mm to fit in a different class. 88 is the limit.

@LongRifles Inc. any news on the Whipple-blown GTO? Hows it coming sir??

 

[roostercogburn98]

Love me some G body cars.

 

[rjacobs]

Welp went to the track yesterday... it was damn hot. When I turned the truck on in the afternoon to cool it down it said 122...

Fueling issues hampered me at the end of the 2nd session and halfway through the 3rd session. Same shit that happened when I was at Ozark International, massive missing and popping. I think varnish is being stripped from anywhere its at in the tank and fuel line and its getting past the sock filter(100micron) and inline filter(reported 20, but guessing 40 micron) and clogging the 7-10 micron micro filters in the injectors.

I ordered up a 6 micron inline fuel filter, a few different QD to AN adapters and some hose. Also got another new set of injector filters coming. I'm going to have a guy ultrasonic clean my fuel rail tomorrow. So from the new 6 micron inline filter outwards everything will be clean. That filter should hopefully capture all the garbage coming forward.

Its to hot to pull the pump again, pump the tank dry, clean it again, change filters, etc... so ill use the $50 6 micron filter as a sacrificial. Im going to run a bottle of seafoam through it to really help break shit up...

Shit busted out and scattered an engine....granted his RPMs were way up there, but I'm betting you aren't planning on diesel RPM levels.

Not overly fond of wrist pin pucks myself, I understand the whys and hows, they just seem like another fail point to me.
Are yours grooved for the oil rings because if the pics showed so I musta missed it ?
