Got a quick question for ya, just out of curiousty...

How high did you spin that 632"?
My friend keeps telling me you cant spin a motor that big over 5k....
In the PGD vid, it sounds like your spinning it a lot higher to me.
He keeps arguing big stroke motors wont spin.

Oh, and I just checked out your website.. that new intake looks purdy :D

That ain't that big. The IHRA Pro Stock engines are 800". smile.gif

It's just a baby, and I only spin mine to about 7500. I think I had the rev limit at 7700 and binged off of it more times than I care to remember.

Tell your friends that I leave N/A at 4700 and if I leave on the fogger it goes 5700 right off the brake so 5000 is child's play.

The guys with the sheet metal tunnel rams routinely take them up to 8500-9000, but they have alum rods. I think I was getting close to the piston velocity limits for steel rods.

Hmmm. Now I have a sheet metal intake, split dominator style EFI, and alum rods - I will either need to change my gears or run more nitrous LOL. Ironically I just ordered some new fogger nozzles today so it is soon to be a PUMP GAS PRO MOD.

I used to spin my stock 283 up to 7000rpm as well.

graemlins/beers.gif Awesome! Thanks for the info...

BTW, your one crazy mofo :eek: A man after my own heart. graemlins/beers.gif If only I could afford to do it :(

As a comparrison when Ryan talks about piston speed his 4.75 stroke at 7500 is the same piston speed as a 454 at 9000 rpms, a 427 at 9674, and a 350 at 10,286.

There is some perspective for you. He is winging that dude!!

Hi guy,

I STILL wanna build onna them standard deck height 588" motors using a 4.375" crank that we chatted about a while back!!

pdq67

that is AWESOME, I love it!

There is some perspective for you. He is winging that dude!! Except I "was" swinging a LOT more weight on the end of the crank at that speed - and probably a contributing factor to why I broke a wrist pin.

What I think is really wild is how high some dude spin their 706's! That's a 5.300" stroke and they often have much higher decks and 7" plus rods!

Correction - I WAS winging it. Winged some through the lifter valley and some right out the side of the block! LOL But, I fixed that weak link so what's next?

66 283, you going to modify the car to fit a wider tire on it? You already have major traction issues, and with the "smaller" cam, and the EFI, you should be making more torque, at even lower RPM.

Yes. Bigger tarz.

Nice manifold. Using an Dry N20 system?

How large inj do u use? And what type of ECU?

Went smaller cubes, E85 fuel and Vortech instead of large Cube engine... Not dynoed yet ;(

I will be running multiple dry stages. Not what is pictured above - annular nozzles near the flange.

I haven't bought my ECU yet - likely bigstuff3 but maybe accel dfi. Injectors will be 160lb/hr.

I'm more serious this time - I expect big power from this engine and will have the chassis and tire to match. It will also be much more streetable this time with the EFI and smaller roller. The eventual goal is to drive it to the track, go 180mph, and drive home.

Thats seams like a serius Streetcar...

So how small is an roller "small" in that large Cui engine?

Im Running Microtech this year too. 160lbs too.

Solved Fuel pump, filters etc?

Who makes Bigstuff3?

John Meaney makes bigstuff3. I think he developed the holley, accel, and fast systems also and this is his own.

www.bigstuff3.com (http://www.bigstuff3.com)

I am running my same product engineering pump and adding another motor. Good for 2000+ hp.

A small roller is "about" 276/291 @ .050" and lobe lift below 500 w/1.8 rockers.

I feel a matchup coming on...... I wonder how much it costs to ship a Chevelle from Sweden...

:D graemlins/beers.gif :D

Sorry to say but i sold my 69SS Chevelle and got a 72 pontiac lemans. Its an GM A body still ;)

Hi Godsend, That Lemans body is pretty light if i remember correctly, somewhere around 3100 pounds? I think a blown 540, 555 or 565 is about right or maybe a shorter stroke 522 or 532. If 66-283 hadn't leaned on the juice so hard he would probably have won the pump gas drags. Two bottles will get real low after a couple of passes if set on 400 horsepower level anyway. The smaller engine with a intercooled centrifical blower, driven by a cogged belt, should be much more consistant and equally as fast as a bigger engine with nitrous. (To 22-283), If you two stage your N2O or kick it in downtrack, like high gear only, you should beat everybody.

Do you have any pics of yur car/engine online 66 283? That is just awesome! Sounds like it's gonna be the fastest "real" street car ever. Edit: I just needed to actually read all the information in the post to see the link to your website graemlins/clonk.gif

Less juice might have done it - but I think the wrist pin would have gone anyways - there were cracks on several of them. Underdesign plain and simple.

I have big tarz now and I am putting double adjustable shocks in the car so traction won't be a problem - so I am building some chromoly wheelie bars just in case. Also getting weight from 3932 to about 3400 with driver. I plan to use a 35 jet off the brake and another 28 jet on a timer down track. I will have a third stage that I can swap with the second from the driver's seat if I need more or less after the first run.

I left wide open on a 41 jet in memphis but I only came out with 8 deg total timing and that was suprisingly enough to kill the tires. You can't kill the torque of big inches and nitrous with timing.

The bottle pressure doesn't drop much when you tie two 15lb bottles together. After the first run I left at 950 and was about 920 at the finish line. I have 2 bottle heaters and had it back to 950 by the time I got to the staging lanes.

On street night I used to run almost the same jet for 2 full passes on one bottle - so 3 passes on 2 bottles is gravy.

Where you gonna find 700 lbs to drop, or 500 lbs if that 3932 is with driver? I think the PGD say you need an interior?

You might have won the PGD's had u not given so much juice, but there was a few other guys that "shoulda won" had they not broke on the track, or didnt make the full cruise, etc. On the pass you blew the motor, how was the run looking? Did it show u were in for a good ET or still a no-traction slip-n-slide?

One more Q, how big of tires u plan on wedging in there?

500lbs. I'll see what it amounts to when I'm done.

Remember, PGD's only require interior to the back of the doorjamb so I could drop my backseat for a few hours. It is 60lbs. My passenger bucket is 55lbs and a light temporary seat to replace it - there is the first hundred.

I have huge ford torino drums on the back of my car, and factory disks on the front. Stock control arms, my hood with bodywork weighed an embarrassing 48lbs BEFORE the hinges.

So we are getting close to 200lbs. The driver has lost about 25lbs so far... halfway there LOL.

I already own fiberglass bumpers that are painted!

The 3932 was also with 20gal of fuel - if I got to the track with 8 gals for example that's 12 x 6 = 72lbs of fuel.

That's ballpark 300lbs.

And a lot of little things add up! I'll gundrill my rod bolts and main studs if you dare me. The car is not gutted or bastardized permanently in any way.

I'm not saying I could have won, someone else said it. Coulda woulda shoulda ain't good enough. I had the horsepower but not enough time to tune the car. (there was snow on the ground at home)

How big are the tires? :confused: ;)

My engine is just a small 468 ;) Will be upgraded with aluminium block after this season for more bore. And less weight.

Will be weighting in @ 3300 this summer i think.

Hope you can shave that much weight of your car. That will get lower ET for sure.

I will compete in a another event. In Belgium. King of Europe. Fastest streetdriven car, Dot and road legal. A non prepped airfield. ;)

Ever considered E85 fuel? But then its harder @ a pump gas shootout. But everywhere else youl get more power and less knocks.

66-283 I give you a HUGE credit just for making the trip and the effort. And you did win an award.

I think next year the competition will be stepped up? maybe not, but that's how these things usually go.

Hi Ryan, I do applaud your effort for even going from Calgary, Alberta, Canada all the way to Memphis, Tennessee as that is one long trip. I heard you had the wrong wrist pins for nitrous and that contributed to the engine damage. Better luck this coming year and hopefully everything will stay in one piece. There are a couple of interesting articles on nitrous at fastlanenitrous.com and DragStuff.com that might be of some use to you. My son has a '70 Chevelle that we are hopeing to get into the eights this coming season. It's really hard to get a Chevelle below 3300 pounds but the 66-67s are a little lighter than the 68-72s. My son's is around 3375 plus the driver and is kinda bare inside. (3620 total). We also have to add a couple of things yet, like inner fenders & some lightweight carpeting and are going to change the rear drum brakes to Wilwood Pro Street Discs to match the fronts and get a little more stopping power.

I won't have the car back together for at least 2 months to weigh it so time will tell how much weight I can remove. Things are adding up though and before I was making NO effort to make it light. Ironically i just ordered new light wilwood rear brakes with my new axles this morning.

Next I'm ordering a hood to clear the new induction, which will save me at least 30lbs, as well, the intake is about 15lbs lighter than my cast one!

I was leaving most of my ET in rubber and smoke - that should all change shortly with the new boots.

Here is a pic of the new TARZ. They should be big enough to do some damage.

http://www.lumpracing.com/gallery/P1010022small.jpg

Thats a lot of tire. Those the 33x18.5s?

yes. And the factory backseat is in the factory location.

pretty cool to still be able to sit infront of a steamroller tongue.gif I'll be honest, I liked the look of the smaller tires better, but you needed the traction. I look forward to see how well you do this season smile.gif

me too but I can't remember how many times I have seen guardrail and how many aborted runs I have made - not to mention the close calls on the street.

Are you still running ladder bars? or did you switch it?

Ladder bars. 4-link would mean no back seat. Technically this isn't a "back half" because the trunk is stock except for the wheel wells. So is the floor.

The new ladder bars are LONG and chromoly though. ;) And different shocks.
