Can a stock 88b motor with Python3 pipes, Pro charger and power commander make 85hp?

Fatboy · « **Reply #1 on:** March 28, 2006, 08:27:30 PM »

Sure....depends on who's running the dyno!

Will it make the same number or even be close on other dyno's......I doubt it.

Lot's of ways to produce a number using a computer.........JMHO

Seems like a lot.

They make some where around 58 to 60 HP stock I think you would need to do more than those changes to get 85 just my guess.

Its not a happy dyno at this place, no games, the torque was also 85 points.

jimp,

The best improvement I've ever seen with just pipes and air cleaner is approximately 20%, and most fall into the 12 to 15% range. For comparison, there are several dyno sheets on this site for SE 103's with the Freedom package and dyno tuning by Brad putting out 100 to 103 hp, versus a stock figure of approximately 84 hp. If you figure the average stock horsepower for an 88-B is 58 hp, a similar 20% increase would only get you to 70 hp. IMHO, 85 hp with a stock 88-B, pipes, and a/c is impossible.

Jimp, this is like the third thread you've started with some dyno numbers that seem, well, extraordinary. Don't know what happened to the images in these threads (the dreaded "box with a red X" is the only thing that appears, now), but the commentary is still there:

What's the story on this particular one?

Ya..and I bet the torque line is flat at 85lbs from 2000 to 5000 rpm...just like the "secret" build on your friends bike. 85hp/85torque ... ..from a stock motor ..or a 95" with stock heads and cams....hasnt happened yet in the known universe where we all live...maybe in yours things are different.

Yeah, 'er 'uh, jimp,
Not impossible, I suppose, but highly improbable. JMHO. Later--HUBBARD

JimP,

What liquid was used in the fuel cell? Was nitrous or a blower involved?

I know the guy that's it, that's why I asked the question because I find it had to believe myself.

Check here - ProCharger for some dyno runs with this system.

With a stage 1, Rineharts ( true duels) and a PC I was at 74hp and 75tq. Can't say it can't be done but sounds kinda high.

tommyo · « **Reply #14 on:** December 23, 2006, 11:37:04 AM »

Just went to the Procharger site... just kinda crused over it. I think those #'s might be right.

SPIDERMAN · « **Reply #15 on:** December 23, 2006, 12:19:24 PM »

This is what I've been saying since I joined this site. Gotten beat up a couple of times too as a result. Dyno numbers like this 85 hp while true don't mean squat and don't tell the whole picture. 85hp from an 88" motor with only pipes, breather and PC is actually on the low end of what they can do by advancing the chit out of the spark, doing away with the rev limiter and running the bike up to near grenade status to produce the highest Hp number they can. I am not at all skeptical about this. However, I would imagine the elapsed time numbers are burro cart slow and the bike would overheat in real world riding conditions in a matter of 20 minutes. I am extremely skeptical however that they got 85 / 85 on the same dyno run. My guess is they ran it a dozen times, tuned it to get the max in each area individual and are posting the results as collated and not from a single sheet / run. People forget that a dyno is a tool, used to help the tech tune the motor to do certain things within the capabilities of the parts in the motor. There is a huge range the tech can tune the bike to. Max hp, Max Tq, best ET and a combination of all three. How the tech tunes the bike should be a factor of what the rider wants from it. I don't think I need to go into any detail about that. In a nutshell it comes down to what you like your bike to do best. One final thought. This number 85 hp is well below the 1 hp per cubic inch which is considered to be the bench standard for moderate performance. TQQ numbers often exceed 1 to 1 even in moderately tuned motors. Max performance is when you exceed that standard, so as I said, it isn't really all that big a deal, but I think there's more going on here than what the numbers would lead you to believe

I think everyone except 'd00d missed an important part of Jimp's first post, including me. I assumed pipes, a/c, and power commander. But a Procharger is a blower, not an air cleaner. That changes the entire picture, and I have to change my earlier opinion that this combination couldn't make 85 hp on a stock TC88B. It could conceivably do better than that, depending on boost levels.

Jerry,

You are on the money and I stand corrected.

SPIDERMAN · « **Reply #19 on:** December 24, 2006, 08:29:29 PM »

Back in the day when me and Beags were building 96hp 80" Evo's , Magnacharger was advertising 100hp from a stock 80" Evo motor just by bolting on their supercharger. If a Hypercharger is a " "blower" ; on an 88" twin cam motor it should produce well in excess of 100hp. Why the hell would you go spend the kind of money a blower cost ( over $3k) to get less HP and TQ than you could get by having a good port job on your heads, some nice performance cams. a stage 1 breather, open pipes and a PC or SERT dialed in right. You know it's Christmas eve and I should be real charitable here, but peace on earth good will toward men aside, this whole thread is just off. Sorry to be a humbug, but it is what it is and what it is, is wrong for a dozen reasons.

A hypercharger is an air breather assembly from Kuryakyn.
But BB in 1991 my 88" Axtell mountain motored Sporty made 130 H/P.
Only made power from 4500 to 7000 but that was enough to run 10.5's @ 130 all day long.
Was the "U" class (unlimited street) champion in 91 and 92 in the AHDRA.

SPIDERMAN-
According to the ProCharger link I posted above, while running 6 PSI, the otherwise stock TC 88 motor delivered 95HP/89TQ on 91 octane pump gas.

You started a thread and stated some things. I'm not accusing you of anything in that you said from the get go that you were getting info off a website for a product. I was commenting on what you posted. This isn't high school and I don't accept assignments to go off and do a bunch of research on what other people post. I stand by my comments that what was stated ON THIS THREAD did not add up. As to whether the website for this blower contains a law library worth of quantifying statements or not is not up to me to chase down. Next time you start a thread Dude, post everything you have to say up front and then the rest of us can work from the same point in offering comment. That's why I said this whole thread was " off " The manner in which the thread developed was not the way we discuss things around here IMHO

I did not start the thread. I merely added my opinion and asked for clarification about what you offered.

I've set up and tuned several 88A & B motors with nothing more than SE AC, Pro pipe, SERT, and SE 211 cams that turned out 90-92 hp and 94-96tq. Dropping the cams, I average 80-82hp, 84-88tq. You can split hairs about number differences you will never feel, but yes, using a blower on a stock 88b should give you at least 85hp/85tq. There are cheaper ways though.

Dyno numbers can only be compared as numbers though. When looking at a dyno pull, disreqard the max values and pay attention to how smooth the line is and where IT'S value is. Jagged smoothing, overadvance timing, underadvance timing, fuel issues, and correction factors alone can increase a max value 1-5hp with out really giving you anything.
