2000 and up HP to the track


I have the magazine arcticle for the 2000 SRX on what the dyno was measured at. I don't remember the #'s, but I do remember they were more than impressed with the out at the track, due to having problems holding the sled to the track dyno. I rember them comparing it to the 1000 T-Cat. I have to say that my 2000 SRX could only be beat by a 1000 T-Cat, that was even up in Canada. Brad
 
Boomer, Jeff said your next. I just might have to come on down a take a peek (LOL). Did you see the 2002 SRX Jeff's got upstair? Can't wait to look at the dyno sheet, guess there was astronomical gains.

I was told that this 2002 with a 780 BB with mega pwr heads Bender BB pipes, V force 3 and completely clutched ect.. was putting out about 91 HP to the track and that was about 8 or 10 more than a stock Apex. So 80 Hp to a stock SRX would really have to be setup well.

Here are the resuts I got with our belt drive system on the dyno vs the chain drive. Lots of factors roll into the HP numbers on a dyno. The lower you are geared, the Higher HP numbers you are going to have. Surprisingly with the belt drive system hooked up our gearing was even lower then the stock ratio with the chaindrive so if I were running stock ratio with the belt drive the numbers would be even higher than they show. Also in these runs I was over reving by about 150 RPM, the Pipes I am running like to run about 8350. Hope this helps you out.

If you know how to clutch you can get over 83hp to the track from a stock 2000-02 srx with the stock chaincase and all!

That would be over 150 HP with that rating. My sled was still clutched for my stock pipes when we did this run so it was over reving a good amount.
 
You would think more Hp to the track because of all that 4 stroke torque. You sell that SRX Shortstop?
 
Well the proof of the dyno sheet is posted right on your advertisement spot on this website, Ulmers did it! also if you refer back to Snow Tech magazine they got over 80hp to the track as well, with a helix and spring change on a 2000 srx test mule.
 
There are more factors that play into the track dyno then you would ever believe. I could put my sled on the dyno if I wanted and make it read 85 HP to the track if I wanted to aswell. For a sled that is setup like a lake racer or has a low gear ratio like mine (1.60) it is extremely difficult to get 80 HP to the track. My sled is jetted fat to begin with in winter weather and we did my dyno in 60+ degree whether. If I geared my sled to 1.80, and ran a low lug height track, I could easily achieve impressive numbers but that is not the riding I do. I run on lake primarly and run 123 on radar with fat jetting and over reving and a viper front and rear suspension all on a stock engine. Track dyno numbers are very inconsistant inless the sleds are setup the exact same way.
 
I am pretty sure Ulmers know how to use the track dyno they own one, do you?? No excuses Matt, this isnt a argument its just telling you a fact without sugar coating it. All you do is brag how fast and how good that sled is and to tell you the truth, its no faster then a average stock srx is! You have all that lightweight stuff on it, pipes,belt drive, alum drive axle, alum front suspension etc., all that fancy stuff on it, all this weight savings and this and that and its no faster then a stock srx is. Srxmagic ran 125mph with a stock srx on radar gun, I have gone 127mph on laser radar with a stock 02 srx motor with lowered shocks,oversize wheels in skidframe. So you need to do some more work before the "sled of all sleds" will be able to set a new bar for everyone else to work too.

I remember that test! i also remember when the 2000 XCR came out and they were raving that the thing was such a stump puller because it had 80 horse to the track in stock form. Those XCR's are toads in stock form lol. SRX's really can throw down some impressive track horsepower numbers with a little tuning. They have quite efficient drivelines.

Never said mine was the fastest of the fastest. When I ran 123, the sled was pretty much stock, didn't have the belt drive in it, no aluminum drive axel, pipes are the same power as stock and I had a viper suspension in it. I never, never said ulmer didn't know how to use a track dyno, I said that if the sled is setup differently, you are able to get higher numbers out of the dyno. My sled is still running stock at this moment besides pipes and front suspension so there is no reason it should be any faster than a Stock SRX. I am always up for a good race, i'll try to find one of your ported motors somewhere and race it.
 
Here's what we've seen with good setups for an average with everything up to temp (engine, pipes, clutches all heat soaked). All tested with the same track as a stock SRX (except the Phazer because it only runs a 14" track, but otherwise used the 0.92" Yokahoma track for even comparison). We generally try to setup as close to exactly the same as we can (track tension, gearing, type of track, etc).

2002 Viper: 71-72 hp

2001 SRX: 83-84 hp

2003 RX-1: 80-81 hp

2005 Vector: 68-69 hp

2006 Apex: 85-86 hp (have seen as high as 93 hp when set up for a 660-1000' lake race)

2007 Phazer: 45-46 hp
