Some shitty pics I just took of the dyno's from last year.




Now if I can figure out how to send this video over to you.

 

It's not "theoretical" if it's long-proven. Do you have any explanation as to how you're able to break the laws of physics?

 

Think what you want, I ran 22 PSI on the stock turbo for over a year without damaging the engine. Just a beater car and experimental. This is what I do, I try to do the impossible. And there are plenty of people here that have seen it and know it's true.

 

Maybe you don't know how to put the laws of physics into play. Yes it's hard to do this, and it took a great while to make it do this, but it can be done.

 

And you think you're the first one, in all of your infinite wisdom, although there are thousands of other FC fanatics out there trying to acheive the same goal. The laws of pysics just DONT lie, there are people out there that use high tech computers, exact weight balancing and performace mods to get their cars to be as fast as PYSICALLY POSSIBLE. You think by throwing on a few aftermarket diddly-doos that your car will now hit 200mph... with only 249HP? Come on, if you were going to lie at least say you had 500...

And 22psi on a stock turbo... wow. The mazda guys did not design the turbo to hold near that much boost, and i think they did it for a reason. If you want more boost you go aftermarket, ive heard the highest possible boost SAFELY on a stock turbo is 15psi max... im not calling you a lyer because you hit 22psi, that is very acheivable. But running it that way for a year and not hurting anything.... i just dont believe it.

 

I do this for a living. I own and run a shop here in Denver. I use plenty of the same stuff as everyone else. Corner balance my cars after everychange. I do plenty of road racing. And I know I'm not the only person trying this. I'm not just throwing in aftermarket parts. I'm actually fine tuning everything, from grounds in different places to moving splitters 1/4" to get that much more air flow to my oil cooler without taking so much away from my radiator. I know all the in's and outs. I told you, I've been doing this for years and make a living doing this.

As for the 22 PSI thing, I know they weren't meant to be run like that. They start blowing hot air after 12 or 13 PSI and then with the stock IC it's almost useless. But that wasn't the point, I did it to see just how long I could do it. In the end I ended up with a cracked apex seal after 25K of driving it like that. Now you have to understand, I wasn't driving around boosting 22 pounds everywhere I went and in every gear. That was like a couple times a month just racing people and having fun. It was my daily beater and another experimental car. I know whenever I get a T2, I can just pull the wastegate and call it good as long as I have a fuel pump, You can do it with the stock one, I just wouldn't recommend it.

And yes I know I should go with an aftermarket turbo, but again, it doesn't look like you read the whole topic. I have a 60-1 or a T58 ready to be thrown on once I'm done messing around with this and getting as fast as I can get with the stock turbo.

 

came back.........i had to.....now i'm off to bed again....send me the vid....still doesn't fit together how a RELATIVELY stock TII hit 180+ mph......it doesn't fit.....for ***** and giggles....take a pic of your engine bay....and please focus in on the turbo.......and just to be a dick about it can you use a 1/2 full glass of water with a lemon wedge and a straw going through the lemon.....please.

 

I missed this earlier. 7500rpm in 5th with stock gearing and tires is only 170mph, and with your slightly shorter tires it'll actually be a bit less than that. If that truely is your top speed then power-wise you're still a fair way off 180mph.
Oh I assure you I do. But if you don't believe me, have a read of this page. Note the important bit about the relationship between power and speed.

 

That's funny, someone already did this calculation earlier and came up with around 188 to 185 MPH. Which is what my speedo was near, and also what the dyno said.

 

I still have a hard time with this because the stock car has a hard time pulling in 5th gear.....

 

i used the calculator on the link i posted earlier and got 185mph running his tires with the .719 5th gear, 4.1 rear at 7500rpm. i also mentioned that no one would believe he got to 7500rpm in 5th gear. and as for stock turbo, i'm just amazed.

 

Will do tomorrow. It's really messy right now because I have everything rigged to run right now until I get the FD mani polished and on to clean everything up. The video was too big to upload through mail, any other idea's?

 

I still don't think the dyno speeds are not accurate either.....like it was said earlier: therre are other factors to take into consideration.......wind resistance and the tires/rims you are running......it might have matched your speedo but in real life applications(outside the dyno) its accuracy will decrease. as I said earlier tires alone throw the speedo off.

 

Help me figure out how to post this video up so everyone can stop bitching. And the car pulls great in 5th. I already offered to take someone on a ride to prove if anyone knows someone in denver, and if they do, they probably already know me or of me.

 

no more ideas..i'll check it out tomorrow.

 

I also agreed that different sized tires throw the speedo off, but I also stated that they are almost identical to stock, and we ran our cars in front of Off duty officers at the track and everything was dead on.

 

249rwhp is not exactly stock...

Check the maths for yourself then:

Stock S4 5th gear ratio: 0.762: 1 (not 0.719:1, that's S5)
Stock diff ratio: 4.1:1
Stock tire rolling radius: 300mm or 0.3m (i.e measured from ground up to center)

7500rpm / 0.762 = 9843rpm driveshaft speed
9843 / 4.1 = 2401rpm wheel speed
2401rpm x 2? / 60 = 251.4rad/s
251.4 x 0.3 = 75.42m/s
75.4m/s x 3.6 = 271.5km/h
271.5 / 1.61 = 168.7mph

Call it 170mph...

If you redo the calc with a 0.719:1 5th gear ratio you do get 179mph, but that's not what we've got.

 

N/A 5sd with a 390 final, on rollerbars (bike upstarters) in 5h gear

 

This car is an S5 which does give it the .719:1.

I'll measure the tire dimensions in a little while.

 

why doesnt anyone help him get this vid up, id love to see it, id also love to see you guys quit arguing, i also belive that 249 rwhp really isnt very much stock at all... why do you keep saying its a stock car, maybe stock turbo, but thats probablly about it... so give him a chance, get some ***** and help him with the vid

 

he can't send it to me cuz it is too big to send over AOL.....

 

about what flywheel hp would his 249whp be at?

 

 

HAHAHAH scott and nzvert = awesome.

249 aint poop! yes, that will be a quick little car, but this guy is claiming a 185mph run on, in this case, a "stock" car. no, its not literally stock, but compared to actually high-mph cars, its "practically" stock. its like saying "there are no girls in this town!" its not literal, dont quite know if it counts as a figure of speech, just a way to say it. sort of an exageration i suppose.
and yea, NZ, he mentioned earlier it was a turbo2, then later gave the year of the transmission (90).
