As some of you know a couple of weeks or so ago I took my Type S to the local workshop to install the AEM cam gears and V-afc installed.
These would pretty much complete the modifications I wished to make to the engine after also fitting AEM CAI,UR Pulleys,Tanabe header and exhaust.
Well unfortunately there was a delay.
The dynojet (belonging to a different workshop) was broken. It meant I'd have to wait 2-3 days before it was repaired...but no big deal.
Three days went by and I called the workshop for the base dynojet figures they'd be using for the cam gears and V-AFC...
"161HP 124.2Ibs torque"
I nearly vomited my liver.
a "But that can't be right".
b "Why? we thought it was really good, at least 30hp more than any ITR we tested, we expected around 128hp"!
Well the liver stayed down but I was as confused as a kitten in a litter of puppies.
I tried to stay composed as I replied...
a " But this is a Type S it can't possibly have only 'fig-wank-ures' like that"!
He replied...
b " Oh Andy! don't worry about that(???) we had an FTO in a few weeks ago, fitted a Mivac controller exhaust, filter and the power run produced much lower figures than the stock FTO figures, We know the figures are wrong but thats OK(???) 'cause we tune the car to the power curve produced and advance, retard etc,etc on that basis!"

OOOOH THATS ALRIGHT THEN! I'LL BEND OVER SCREW ME SOME MORE!!

Well since then I 've felt like my dogs died and I've discovered I'm pregnant.
Yes that right I'm going bonkers.
Next week I'm taking it to a different dyno so I can find out the *true* power figures.
But tell me fellow Ludites....
What do you make of this...?

WHOA! THey are wayy off. Take it to another shop, have them dyno your beast, then once you get the figures you deserve, take the sheet to the shop that doesnt know how to tune. SHow them that they suck and they've lost a customer. ;-)

Forget the numbers... The torque and power curves look absolutely beautiful. If they actually did tune the V-AFC and cam gears, they did a great job of that... Your power curve is very linear - no VTEC spike at all. And your torque plot is about the flatest I've ever seen for any Prelude! Looks great to me!

But what if he had those nice linear lines AND the 10-12 more horses and 10ish more ft. lbs o trq. that he SHOULD have?? That would be nice!! My base dyno'd better than that with less mods.

they're dyno must be whack if a type r ran at 128hp.

They spent nearly a DAY tuning it on the Dynojet. I just wish they could have given me the TRUE power figures.

My old friend *Thatchmaster* wanted to take a look at this so I'm sending it back to the top in case he's missed it...

Temperature? Pressure/Elevation? Humidity? Tire size? Tire pressure? These will affect things tremendously. Plugs, dizzy cap and rotor will as well.

Obviously the dyno is off... This would not keep them from tuning the car, however. I think what andrew is pissed about is that, since the dyno is off, he can't know how much power he's really making.

Guess you'll have to another dyno. What I would NOT do (as someone had suggested) is carry the dyno sheet back to them. What you'll have done is helped them tune their dyno for free...

Yeah for real just let them know in a nice calm way that they are *****NG STUPID!!!

It should be alot higher. I would say +50 hp. Nice smooth curves though. I would get done somewhere else and blow those people off.

Maybe it's because of the model of dynomometer. That one is a 16B, while the most commonly used is the 248C.

Interesting point Aaron. Is anyone aware of the differences between the two models?
