Hi guys......I'm a month away from lighting the candles on the Mach again and attempting to run 150mph in 1/4 mi on ice at the NBSSR. I wanted to discuss my set-up just in case members of 'Mach Nation' had any helpful suggestions. Power will not be an issue, at least I don't think so with 300+hp on tap.....The challenge will be clutching to my tall 28/38 gearing. 2 yrs ago we ran 140+mph in 2000ft (50 less hp) with 28/42 gear, a 44/40 helix and the stock 225/303 purple secondary spring and a bad overall chassis set-up - no wheels just sliders, another one of my great ideas! This year I'm set-up (pretty much a guess until we try it) with a Goodwin 250/345 secondary and the same 44/40 helix - but with a fabulous chassis producing about 50% less resistance. In order to reach 150mph in a shorter distance, I'm of the opinion (as are some of the pros who have offered their suggestions) that I need to stay close to about 105%-107% of OD, no more. 1 to 1 will give me 145mph, 105% gives me the magic 153mph......If anyone has ever clutched a Mach twin for these speeds, feel free to jump in. Once we get rolling my Race Pac telemetry will provide all the data we need (crankshaft/jackshaft ratios etc) to determine what's happening - should be pretty cool.
Thanks and all the best for the Holidays,
Cliff

great looking sled man, wish ya all the best luck, hope you reach that speed,what did you end up with as for a primary set up? How big of a nos shot you got on that?

Cliff Where are you going to do this run and the dates I am trying to set up a trip in lat Jan so a Buddy and I can possibly make let me know the info Best of Luck and all my support.

I bought the fasted Mach I ever seen in Person from a close friend of mine and would love to support you Quest.

Merry Xmas!
Most of us are pulling for you!
Have you Track Dyno'd it at all to quantify any inprovements you've made in the drivetrain, what worked, what didn't?
Good Luck!

She is sweet Best of luck!!!

Eat well your going to need a good hole shot

Merry Christmas, Happy New Year

Sadly, no I have not "track dyno'd" the sled simply due to my business schedule and the logistics involved in driving from Toronto to the USA to have it done - the motor dyno work has been completed by Bondi down the street from me.....That said, and recognizing how important the 'clutching will be from here on in, I'm in discussions with North America's top track dyno champion who I have asked to consider joining the Mach team (and receive World recognition of course) via an incredibly innovative and sexy 'virtual tuning method' whereby, I send him downloaded run data from my RacePac system (which gives us everything you could think of) right from the track - he opens it in similar software, analyzes it, then e-mails me back the necessary changes as he sees the clutching (crankshaft/jackshaft activity) working first hand.....Christallmighty it's a page right out of Ferrari's FI book!!
If I'm successful in pulling this off, it should prove incredibly interesting and educational to the entire Mach Nation and then some, who have always wondered what about all this theory, what is really happening as a sled winds up thru a 1/4 mi run at WOT and how do we maximize the performance.
Stay tuned,
Cliff

cliff, for sure that is awesome technology and wish i had one..... setting up my sled for 500-660 races on snow be great to have that at my finger tips to take the test time out of it/educated guess work out of it.

50% less resistance?? Wow! Some space age grease inside those bearings?? hehehe

[Bobby_G]

best of luck cliff and safe travels

Thanks Robbie.........Here's what I did to reduce the resistance - the hyfax was cut down by 50% to allow the track to run on the wheels (much faster on ice) I also added more wheels, remove each and everyone bearing, removed the seals and cleaned out the grease, filled them with 10 weight oil then reinstalled the seals - they are still spinning the last time I looked!......Another PM just in, how much for a Race Pac and what does it do? Thankfully EGT/RacePac is a sponsor, this system is $2700.00. It records speed (to within 1mph) egts, o2, coolant temp, fuel pressure (to within .1 of a lbs), crankshaft speed, jackshaft speed (with ratios to show any clutch slippage) and rpm again to within 10 revolutions. This information will provide an incredible data pac for me and my tuner, it is a simply track dyno on ice......Now all this said, we'll indentify things that have possibly not been known before with the FI Mach at this level - what happens to fuel pressure at WOT with 300+hp, does it drop or can my custom built high flow pumps keep up - what about yours at high speed? If there is a problem with any of the systems being monitored (if fuel pressure drops below 58lbs) I get a red warning light in the top left corner of my dash and I abort the run (it's all I watch for 8 seconds). Back in the pits we determine what happened, make the correction with the motor hopefully intact - unreal.
One guy asked who I'm racing, I'm in the Pro-Open 1000cc class, I'm assuming and welcome lots of competition. Here's how I see it, much like life itself, 50% of winning is just showing up, the rest is a burning desire to succeed. I think we've got them both covered. In the end we may be out gunned, but never out classed. When I come to the line, win or lose, we'll put on a show, 'with style' and representing all those folks who have so kindly helped me alone the way - it's how I roll.
Last question - what happens after 150 - the Mach is in it's last year, in March of 2012 it will be given an honourable discharge and retired to my collection along with the spare motors etc.......Next up will be my 'trail rocket', the new Straightline Performance 220hp (n2o) 2012 E-tec 800!

sure feels like the 1000 is on its last legs, even for me not much more(in my class of racing i mean)

buddy runs a couple '11 800 etec's, what awesome sleds/motors......sure would be wicked to put a little squeeze to her hahaha.

that racepac sounds like the bomb and the way to go.....cant wait to see what you come up with while on running the sled.....

More PM's on the chassis - here we go. The track is aligned to perfection, with the outer guide nubs removed - not needed and they rub on the chassis. The track's angle of attack is such that only the back 18" touch the ice, much like a hydro on plane. The track is a simple 'straight rotation' from the front sprocket to the rear 10" wheels - it's as tight as a banjo string for max top speed. The sprocket cogs have been shave at the back so they can't touch the metal window clips as the pass, only the front of the cogs have any contact - they are extros. The chaincase has been blue printed (aligned) in such a way that there is as little pressure on the jackshaft and sprocket bearings as possible (this was huge) the chaincase bearing inner seals have been removed, all grease blown out and the chain runs in ATM, not gear oil - it's thinner and causes less resistance. You can spin my track with your hand - Here lies the 50%!

just curious, or checkin, 300hp, is that with a turbo? i would think so, but then i see that boondockers box? so you must be running 1 huge hit of nos to do that, but even then i would think nos would have its limits its self as to how much power it can add?

[mack241]

This thing is going to fly Good luck with the run.Also we should start a pool going on the exact speed number of the first pass
I say 152.65mph anyone else
