Horsepower is simply a mathmatical derivative of torque. If you are making 250 rwhp at 3000 rpm, then you have 435 lb-ft of torque at 3000 rpm. In case you don't know, HP=(torque*rpm)/5250. We'll wait to see your dyno sheet....nice numbers BTW.

 

I Joined this crap just to let you fools know the StreetdreamzNY is right he has 240 horse at 3000 rpms. Why dont you people understand what you read before you read before you tell people how much horse they have. I Was there standing next to his car at KDR when it was done....dont be mad because heas has more horse at 3000 than you have at peek horse

No problem but you're wrong.

 

i scanned my dyno but it's 6.2 megs and i don't know how to post it. anyway this is not what this thread is about and i don't want to argue with you guys and take away from artguy topic. but i'll see some of you at the track and will beat some single and upgraded twins rx's p.s i could be reading the dyno wrong but again not trying to start a flame war

 

Looks like you just made a fool out of yourself

streetdreamzny just proved he doesn't know how to read his own dyno sheet by stating his peak tq is 276.9. He made a simple mistake of confusing the tq line with the hp line. As further proof he confused/switched them, he probably thinks he's making 137tq at 3000rpm along with his 240rwhp(which is impossible).

Thus, the real answer is that he's making 137rwhp and 240tq at 3000rpm.

 

fagboy give us a whole run YOUR FIRST turbo means dick. a full run from 2000k to 8000k would be fine and I will shut up thanx

 

wish i had a setup like that.

 

If you guys look at a dyno sheet with hp and torque curves - as JspedFD points out..if you follow the little squiggly lines you'll find that they cross at I think 5250 rpms (?) The hp will always be lower than the torque below the crossover and higher than the torque above the crossover. I've done this before and I'm sure everyone else has at some point if you are not used to examining dyno sheets. 240 rwhp at 3K is impossible for a stock turbo/manifold FD..but I'm sure artguy will put down some good numbers.

 

HP and lb/ft cross at 5250 rpm because of the formula used to calculate hp that rynberg posted:

HP=(torque*rpm)/5250

Torque is a measure of force only, and horsepower is a computation of work (i.e. force applied over a period of time).

Before 5250 rpm you always are multiplying torque by a factor that is less than 1 to get the HP number, at 5250 rpm the two figures are identical (because you are multiplying the torque by a factor of 1 to get hp) and past 5250 rpm the hp number is always higher because you are multiplying torque by a factor of more than one.

I don't know who came up with the 5250 number originally, but that's the way it works.

Hope this is a decent first post, I've been lurking/searching for a while but felt the need to chime in.

 

haggus...my first turbos numbers do mean a lot to me...and once I get the sheets I will say why. I am after the most streetable rx that is possible. I want as much possible downlow power and I want a good umpf up top too.

RIKKI: I expect a very wide power band. I do not know if what i have done this winter will top the bnr set up top. Im running sequential and built the car to do that. I expect to whollup them in terms of response though...and not just because of the dual ball bearings. Send me an email/PM and I will tell you a secret. you have your sauce..haha..i have mine.

if all goes well my wiring harness will be in tomorrow...i dont know if they will have time to get her on the dyno or not...louis from RRR said they are looking at tuesday for the results.

Hey man, that **** is uncalled for. Who the hell do you think you are, lets make it clear that around here you are nobody. You should be glad Artguy is giveing up any info at all to your sorry ***. I know what its like to spend a ****'n pile of money on turbos, tuning, ect and then have people just expect you to hand **** over like they paid for it. If you want people like me, Artguy, and everyone else that actually tunes thier cars and spends money to give you information on our findings then stfu and start listening instead of demanding and bitching

Dont worry you guys arent the only ones with "tricks" up your sleeves lol

Streetdreamzny - Try setting your scanner resolution ot 72 dpi or lower (64 dpi). I bet when you scanned your dyno you had it set up at a very high resolution.

If you keep bumping down the dpi you should end up with a mall enough file, and it should be more or less readable.

don't give up on us dyno sheet junkies

 

streetdreamzny you can email it to me at jason.manley@sierra.com and i will fix the size and post it

spo...do tell your tricks....I want to know. I will go over everything I have done once i get the sheets. I want to see if it worked first. ....and thanks for sticking it to haggus...im in agreement with you. getting this far has been a tremendous amount of research and effort. I was a guinie pig and that was frusterating for a long time. But...i learned a lot...am still learning...and just might have the success i have been hoping for.

we shall see very soon...perhaps today...perhaps tomorrow...barring any unexpected detonations or other good times.

Well, I've got a few ideas but nothing that I've actaully atempted to do. I'm still enjoying my car and dont have the desire to start ripping into it again lol.

I hear Barrys car is spooling like a mother though and he still has a hi flow cat. I was a avid fan of seq and still am to an extent but I REALLY like the look of my engine bay with no seq in there. I dont have one thing under my uim except fuel lines and that is it!!!! No wires, no vac lines, no nothing!!! Eventhough I gave up some power from prob 2500-3500, I gained from 3500-5000 which is a more important range for me. In a track setting I dont think I'd like a instant 150+rwhp kick in the ***, its like hitting a 150 shot of nitrous coming out of a turn.

Whenever you beat my 125mph at the 1/4 on pump gas then I'll start working on my other tricks

But please share your tricks once you get them working!!!!

It would have been interesting to see the Stage 3s running sequentially - as far as complexity, I hate seq - so many damn solenoids and hoses, but I love driiving it around town and I did a 4th gear run from about 40 mph and it pulled like my 3rd gear used to! I do notice the twitchiness of the sequential system - definitely not as linear and predicatable as the power delivery of non-seq, but it's fun. Artguy, get us some numbers soon..I'm sure you'll put down more power than me down low - keep us posted...

 

if all goes well i will take the car to the rx7revolution next month and see what she does at the track.

I havent heard anything from RRR today. I will give them a call and see if the wiring harness is in or not...hopefully so. I wish i was out there so i knew what was going on better. will let ya know as soon as i hear anything.


jason

 

i was wrong i went to kd today and asked dave he said i was looking at the torque lines not the horse, it gets a little confusing to read when theres alot of runs on one sheet, my mistake

 

You are a better man than most to admit you made a mistake. I think we have all made that one, so don't feel bad.

 

yah...xs works on piston cars as well...not just rotaries.

Id still like to see your dynosheet streetdreamzny


i just spoke with RRR...they are still dealing with the wiring harness stuff...any day now....

Is the wiring harness going bad a common thing with the Power-FC? I've heard this a few times now?

 

wha?
Really? I know the stock harness often gets cooked after years of driving but i've never heard of it going bad as a result of using the power fc?

 

it was my original harness...god damn expensive part too...the last thing i was wanting to do...but can i do?

a new one is going in now.

ok good, sounds like a coincincidens then. The cars are getting old and alot of people getting the PFC.
