Front Engine Dragsters / Finally down the track on second outing..
« on: November 12, 2019, 09:33:28 AM »
Finally got the MW car together and down the track semi-successfully on our second outing.

Been 12 months of assembly, other projects and work.

First time to track since took the car down all seemed fine, burnout was uneventful and I decided to do a footbrake leave in high gear just to see if it went straight and stopped well. Didn't worry about cutting a light and had asked for a single lane run since we were shaking the car down. Car spun just a bit but left straight - felt really good until about the 330 when I got a visor / face load of nice warm oil and backed her down quick - blazing trap speed of 59 MPH. Note to self - put visor ALL the way down every time.

Turns out that the three piece Enderle injection manifold / intake gaskets / china rail interfaces needed some minor machine work and some additional Ultra Grey. Acceleration was pushing oil back into the valley / head corners that found a direct leak path into my helmet.

Second time to track I can report a better outcome. 6 passes, all but one was high gear roll into the throttle leave as we continue shaking down. Best was 5.80 @ 132. The single TB pass was an absolute comedy.....I think I remember three distinct wheelies during the pedal party.
I've got to get the go-pro rigged up in the cockpit to keep an eye on the tach - was spinning a bit around the 100' mark and quite a bit near the finish line. Top end spin I'm thinking is around the point it's coming up on the high speed. Kept going down in tire pressure ended up at 7 lbs. Friend that was helping me out commented the tires seemed pretty stiff - we checked with a variety of gauges in the pits and turns out my low pressure gauge is fubar - 7=11. Our day was over but a new gauge is on the way.

Reasonable tire pressure test session coming soon....

Wanted to sell / Carbon fiber dragster seat - new
« on: September 03, 2019, 12:05:21 PM »
Hey all,

I have a brand new carbon fiber seat from Quartermax that I ended up not using - no holes, no cracks, maybe a little dust from storage. 17 1/2 wide (fit just fine in my 18" car)  13" deep and 29 1/2 tall at the back. Paid 335 - sell for 225 shipped to the Continental USA.

Feel free to text me at 817- nine oh eight - 9119.

Thanks!

Front Engine Dragsters / Re: Interior pan advice please - 3 piece ok?
« on: March 20, 2019, 11:55:14 AM »
Roo - agree and absolutely would do if I planned to campaign this car - chassis is already prepped / painted (2 times) and going together. Hate to any more time / rework than I have too since plans are to let it go.

Too many projects - door car, this one and my Buddy Warren full bodied FED - and not enough hours in the week.

Dzus tabs already in place on upper side of frame rails / crossmembers, etc. Not notching for the verticals will make it a simple shear, brake and punch job. Give me more time to file rings....&^%$#.

Thanks again!

Thanks all!

Rooman - brake foot on the floorpan and throttle pedal has a shelf for my heel. Car does not have a full belly pan.

lol at dropping gloves - it gets awful dark in there too and I can't reach much when strapped in. Makes for some awkward moments with no pit crew!

Think I will just use a one piece floorpan but just bring it flush to the vertical members - be much easier to get it in place and easier to fabricate too.

Hi all - been off the board a bit with some work changes.

Putting the MW FED back together and am replacing the interior floorpan. Current unit runs from rear motor plate under the seat to the rear rails. It is a rip-roaring PITA to get in and out.

This may be a dumb question: Can I remake this in two -three pieces? Any rule or safety conflict to doing so? Current pan overlaps the outside rails and is relieved for the vertical chassis tubes and has a mild bend where the main tubes turn up towards the rear of cage.

Assuming I can do so safely I have a couple options in mind.

1. Main center pan with small 'wings' dzused on each side that are relieved for the vertical members / pedal mounts, etc.
2. Front section pan from seat brace to motor plate with rear section under seat (at bend) dzused in place.

Thanks in advance - appreciate any thoughts.

Same guy that stickered my other two rides.

Inspected and 'passed' it and will drop by to sticker it now that it's painted - we do business together as well so he is here regularly anyway.

Well, finally some progress to report!

Fired up the MW FED - spent some time relearning mechanical injection 101! Engine sounded strong and made great oil pressure. Future for the MW car is uncertain but I'm gonna be strapped into it regardless for a few passes....I decided to go to bare frame / bare block and build it back up. Even assuming I sell it I'll rest easy knowing it's all as good as I can make it. First stop was cert and it passed to 7.50 with no problem.

Next engine came out and down with no issues - pistons were new Mahles, rods are Olivers and crank is a Callies. Wells racing just let me know yesterday that the block is fine, was honed, cam bearings and freeze plugs installed and is ready, heads getting a valve job and new springs / retainers to match the cam, crank should be polished any day.

Frame just got vapor blasted today and paint complete by the end of the week. Wheelie bars and associated small parts headed to the powder coater later today.

Doesn't look like much but finally about to start re-assembly...

Thanks again - was a blower motor in its previous life - now 14-1 CR on Hilborn stack injection. Probably giving a little away naturally aspirated with that wide LSA?

Thanks guys - called around today while I had a few minutes. Bullet cam guys called it as a  Comp Cam, quick ring to them had me the specs and cam card via email. Pretty dang great customer service from both folks.

FWIW cam is a custom grind mech roller, 652 int lift, 657 ex lift, duration @ .050 is 267 int and 278 exhaust with 114 LSA.

Appreciate the help!

Matt Shaff's Engine Shop / SBC roller cam ID help?
« on: August 06, 2018, 03:16:13 PM »
Looking for some help - freshening up my 406SBC and replacing the Summer Brothers gear drive with a regular double roller to help solve an oil weeping problem with the Enderle cover / Summers / oil pan fit. While heads are off to be gone over thought I might consider valve springs......but I have a mystery cam.....

Anybody have any idea what this thing might be...it's a reasonably healthy mechanical roller on a small base circle.

Thanks in advance!

Thanks for that!

Glad to report success - reset butterflies, adjusted BV to 25% and fired right up. Went about three flats leaner and while it's not quite perfect it's 100% better than it was.

Now that I've heard it run and filled my shop with methanol fumes....out it comes. Needs a new pan gasket and it's finally time for chassis paint, re-cert and assembly!

Thanks all.

Thanks - Iíve breathed enough alcohol fumes this weekend to be second guessing myself!
Will check and set them tonight and report back.

« on: July 30, 2018, 12:58:48 PM »
Hi y'all. Got the 406 in my MW car fired up this weekend. 406 / 3 piece Hilborn / DSR pump / 36 degrees timing / 115 main bypass/ 90 high speed at 50# on alcohol.

Started with BV leaked to 25% - small adjustments leaner have it idling pretty well and it's crisp on the throttle once I blow it out.

Passenger side cylinders seem very fat - 2/4/6/8 - most particularly #2 and #6. They are blowing lots of raw fuel at idle. They clean out fine when I hit the throttle but they appear to be very very rich.

Checked nozzles last night (clean), checked valve lash (all good at .02), fresh spark plugs. Going to check / gauge butterfly adjustment on that bank tonight after work.

Anybody wanna take a stab at why it's really good on one bank and super fat on the other....got butterfly adjustment in my head....what else might I be missing?

Thanks in advance!
