how do you guys think is a better set up.
2005 mack z or 2003 or 04 f7 with bikeman f9 or dd f9ss.
i know the mach is a pull rope and 170 ish hp and 118 tq and the 9s in a f7 is alot of work to get it going to the 175hp snd 111 tq.
what do you thiink?

also do u think that the 9s are worth the $
i looked a dyno sheets and the bmp f8 does110.1 tq and 157.3 [email protected] bsfc re at .702....trailable
the bmp9 is 115.3 tq an 177.8 hp @8100 and bsfc are at.593 not trailable
and the f9ss is at109.5tq and 173.1 hp @.705 bsfc ... trailable

if you notice the f9 are not making any more tq than the f8 with single pipe @ both around 110 ish. whats up with that?
is the f9 @ over double the $ worth the same tq and 15 to 19 hpw more?
you have to think that the f9 should have alot more tq than the f8 being either 68 or 111 cc larger! WHAT YOU GUYS THINK?

The F9 will smoke it!!!

I have seen good running stockers beat up on Mach's in a 1000' or less ..............then the Mach comes on pretty strong . As far as the f9 ...your making more hp give or take and you are riding a sled that is nearly 100 lbs lighter . That a tough one..........those MZ's have some pretty long legs . 1/4 mile 1/2 mile ? the f9 . 20 miles wide open on lake ?????????I don't know . :dunno:

well if you know how to clutch and gear I know for a fact that a F-8 will walk away from a clutched mach z no matter how long the run, I run a really big gear and have had no problems with the mach,(except with nitrous) And as for the BMP F-9 that's what I'll be running this year with the twin pipes she makes 190 hp and 125 ft.lbs of torque so LOOK OUT!!!!!!!!!!!!!

I think this is gonna get good!! :doh:

I'm sure it will, but the mach z is UNDER geared on the lake that's exactly why BMP is getting 30/48 gears made for the Z

Does anyone know why the bpm9 or f9ss is not making any more tq than the f8?????{single pipe to single pipe}

well if you made more hp at the SAME rpm the torque would be higher but it looks like the 9's are making there power above 8000 rpms so the torque will be lower.I can't remember the formula but I think it's like this:take your hp.x5252/your rpms=torque,so 190hp.x5252=997880/8000rpms=124.735 ft.lbs of torque.so if you made 190 hp at 7700 rpms your torque would be..129.5948 ft.lbs and so on

Well instead of reading a bunch of dyno numbers which don't mean squat if you can't make'm work for you , look at what happened at Haydays this year. Denny Mousseau won stock 1000 with a stock firecat 700 Even running a new record of 5.28 in 500' with a 700. Last year on the ice at Lake city ice drags both events Dafloewagegoer's stock 700 won the 660 ice drags hands down in the sanctioned stock classes and later on the grudge track . Where he ran several mach's hopefully teamgreen has some pics cuz one of them had Nitrous on his mach and one with a big bore kit and nitrous , still couldn't beat Dafloewagegoer in 660. Then there was the clean up at the Fatman races with the mach's the only mach that ever gave him trouble resides out on Lake St.Clair, But Anthony is a neighbor and we know what he has done. ( lots of homework and testing). How you gonna make your power work for YOU. No matter how much power the mach's make they still have to bring ALOT more than you do on the most EFFICIENT chassis in the world. There is a reason that after 4 years the little ole 700 firecat is still a DOMINATING sled. Its what all other are trying to beat. So if 150hp firecat beats a mach in 660 , I am sure an F-chassis with even 165 hp will kill a mach everywhere. So basically the mach has to bring 30% more hp to the table to compete, that is if the starting gear on the primary don't get the driver first.

There is no doubt in anyones mind the Firecat chassis is hands down the fastest chassis made. Couple that with a short haul race against the bigger, heavier, overgeared, new and the Mach will struggle.

Now lets take a F7 trail sled that does not have chissels, cut track, lowered, etc and I will bring you my trail Mach Z and I want to see the Firecat that beats me over a 1000 feet and no question to top end because it aint gonna run with me. I still want to see how I fare up to 1000 feet but lets compare apples to apples in set up and really the 1000 should win.

Also what many lose sight of is that F7 has been out since 2003 and has many years of guided tuning of motor, clutch and chassis set up. Give the Mach some time and lets see what they can do. Until then a glorrified race sled competing on the lake as a trail sled is no way to compare real world trail sled for trail sled.

Just my opinion.

[/quote]if were comparing apples to apples it would be a F-10,then whats the excuse???

 

[puddytatman]

No excuse.

First if you read what I am saying is comparing trail sled setup to trail sled set up. That is apples to apples and in the same breath I have said the 1000 should win but that it is because it is a 1000 against a 700.

But hell bring a TRAIL F10 and lets run them 2000 feet on ice. Let see who wins to 660, 1000, 1320 and 2000. Better yet lets see who makes it down those distances and if they do lets keep doing it pass after pass after pass. Might as well bring the TRAIL F8 as well and lets do the same. Then lets see what the excuse is and if there is an excuse.

I own both a Mach Z and a Firecat. I am running a Engine Tech 900 which I cannot believe will not hand it to my Mach but until winter comes and we run them in TRAIL form we will never know. I do not know of any F7 or F8 that if lined up on the ice or hard pack will stand a chance against my Mach Z from 1000 feet to 2000 feet.

Geez maybe I got a "good one".

[cjt]

maybe,or maybe you should have got the bikeman F-8 cause I haven't had any trouble with the mach and we ALL have ice picks!! we"re even till 100mph and then my big gear takes over and I just keep going!! (thats just the 3 mach z's I've ran)with the gears I'm pulling she goes 125-127 everytime,with the SINGLE pipe!!

 

[teamfrosty]

I think it´s time for us to see some...


Mach Z asswhoppin



:boxing:

 

[puddytatman]

Well congratulations for your very fast BMP F8. I think there is a guy in NY that would sorely want to know why his can't beat an F7 but thats another story. There are a million stories out there and I guess racing 3 Machs means they are all slow.

One story I like to tell those who think the Mach wont run in 1320 with a F8 is there are 2 Mach Z's on the tar running very good that obviously have the right tuners. The first is Chuck Hamarahs who runs a CS twin piped Mach Z and it's best run so far is [email protected] or very clsoe to that. The other one is my good friend Billy Howards with only its second or third time on the tar ran a 9.87 @ 127.5.

Now I have had a very fast F8 - no way trail and twin piped - and ran a best [email protected] and the fastest one I know of was Looneys - twin piped and nto sure it was trail set up either - and it ran [email protected] so what is the excuse for this.

Teamgreens f7 with slp twins flies . I love that video! :div20:

 

[cjt]

well if you know of two and I know of three I guess I win!! :frech32:
I know everyone here has the "BEST" sled, so do I, thats why it's so much fun to line them up on the lake !! oh well just telling it the way I've seen it ,sure it's different somewhere else.HAVE A NICE DAY!!! :beerchug:

 

[cjt]

must have been one of those very few "slow"ones in that video huh?? maybe your other sled has a cylinder down??????????????????????????????? :banana:

I'm just having fun it all gets cleared up on the lake! :no_bashing:

[nowchild]

It comes down to distance & conditions IMO. And like puddytatman says......compare TRUE trail sleds vs trail sleds. I know of few F8's that would actually live as a trail sled for more than 1000 miles......so most are obviously on the edge.

On ice if both sleds are picked / chisled in the short haul 500-660 feet I would give the advantage to a LIGHT sled ....like a well set up F8 or even a F7. Weight ussually wins with good hook up in a short distance.

On snow with trail studs a properly dialed MachZ WILL eventually win. Its just a matter of how much he lost in the holeshot. In general the Mach has a 5-10 mph advantage on the top end on snow so he's comming. POWER / torque wins on snow and weight becomes less of an advantage the further the distance.

I think very few Mach's were actually dialed in by the end of last year.......actually putting the 118 ft lbs of torque / 170 hp to the track. Thats why many were beat up by dialed in F7'S & F8's. :boxing: I know a few MachZ owners that by the end of the year.... found 10mph ++ in clutching only.
