280.5 WHP Yikes.... here are this guys list of mods...: Engine and Drivetrain: sprintex s5-210 running 60mm pulley Jcw intake with flapectomy and ITG filter GP Intercooler Mynes V2 header Thumper TPR2 .. now upgrading to TPR2R Thumper matched intake MM cam.. ( changed to 1320 Cat Cam)now installing adjustable cam gear by thumper.. Arp head studs 550cc injectors ATI Superdamper Sachs performance clutch kit TSW Solid Upper Engine Mount..changing with vibratechnics from 1320 Bytetronik FullAccess Tuning kit Quaife ATB Differential Aquamist Hfs3 system running 50/50 water-meth -new modification include: JE custom pistons raising compression connecting rods polished and weight matched, arp bolts used. Crankshaft balanced till 8000rpm Not to bad... or maybe just amazing?? Yes?? Just saying.......................... Thumper
Saw that on the other forum too, 280 on a Dynojet is F'n strong, that calculates out to be between 315-320 on a DynoPack. No way I could even come close to that until after my rebuild, but at least I have a target when the time does come around. And 209 ft/lb torque, that's gotta be fun to drive.
well.... I am not ready yet. When I rebuild I will consider it. Seeing as I am at 280+ WHP with just a $250.00 NOS KIT... I will wait before I invest in $3000.00 PLUS in a new blower.... Just saying....................... Thumper
Thumper, need to make a correction to your original post, they did that with the 64mm pulley, not the 60, Holy Crap, now I'm even more impressed.
What's interesting is Moving the Torque limiter on an R53 won't make a change in HP like that. Back in the day the twin charge guys were making 300 ft/lbs of tq on the stock ecu with AFC II that only controls air to fuel ratio. If a torque limiter really effected that it wouldn't have allowed those cars to reach those torque numbers. A change like that looks more like playing with the dyno then anything else. That said his original numbers of 250whp are pretty nice. I mean that's what guys with very built cars and M45's are making so it's no number to laugh at. What's annoying is the dyno graphs don't include RPM or AFR's. You can see on the original thread. Dreammaker's Black Eye Purple R53 - The Projects - TrackMINI.com
LOL.. there it goes... 'messing with the dyno'..LOL Not the FA, LOL You guys..... are all the same. He posted on 3 different sites, they all are fine with the numbers and HOW he got them. The Dyno they used in GREECE isnt one to move adjustments or calibrations on the dyno to get a bigger number. Seems they have integrity !! and are an honest lot!! Just saying................................... Thumper
I'm not saying those numbers are impossible from a sprintex. We know it CAN reach those numbers. I mean my car did. What I'm saying doesn't make sense is how he got them. That is all. You may or may not remember the Mini here in Central Florida that made 250whp/250wtq on a dyno one day (with stock head, stock cam and stock header) by just playing with the torque limiters but since then has yet to make anything over mid 180's on any other dyno since. The Particular local tuner that did his car then locked his ECU and walked away. I got told a story from a dyno operator recently of that very same tuner tuning a guys Evo, put it on the dyno. Got it good and hot, did a pull. Then proceeded to answer e-mails on his lap top while "tuning" the car. He then did a stone cold dyno pull and the car made 15 more hp. He closed is lap top and said done. Hell if I can find them I'll post the dyno my car made that I turned into NASA for a specific number from back in 2010. That IIRC correct was 282 and 234 (Nasa gave me a limit of 286whp for the class)
I'm saying don't believe everything that's feed to you on the internet. And I think that's plenty useful. Do your homework, figure out what the torque limiters actually do on a R53.
Well, this is a very useful / technical MINI forum - go ahead and tell us right here instead of beating around the bush.
Here is another site with the 'story' on it.. might help a bit more. Me?? I have no reason to doubt!! I gather with honest guys and dont need to see any exaggerated numbers.. lol the first to the end wins!! Yes?? Mynes search "Sprintex Equiped mini whines with 280whp!!!! " have fun.. and enjoy the read. Just helping................................. Thumper
Correct me if I'm wrong, but aren't they just saying that the torque limiter settings were basicly holding the motor back from making the power it was capable of and by adjusting those settings it finally, for lack of a better term, let it loose? Seems to me that there should be a lot of power out of a motor with all those goodies. Still sort of freaks me out that that was only with the 64mm pulley & 17.3 lbs of boost though.
The bigger question is what is the Torque limiter actually doing to limit the torque on a R53. What does it do... pull timing, pull fuel (not likely), or close the throttle body? All of these things you'd see it on the data. The R53 has no way of limiting the boost (like the R56 can). There isn't a boost control solenoid and the bypass valve is all mechanical. If it were doing something like pulling timing or closing the throttle body you could easily see that during a dyno pull. It would be pulling it's hair out so to speak on one of the twincharged cars years ago making 300 ft/lbs of torque. Instead it works mostly with the traction control in which you can actually feel it working. No Stand alone ECU has a torque limiter and yet no stand alone ecu makes any significant power gains over a well tuned R53 ecu running parts that operate within the parameters. People smudge numbers all the time trying to sell parts. I'm not selling anything. So believe what you want. If you believe you'll pick up 30hp from turning a torque limiter off. Be my guest.
Quick qustion that needs to be asked. On the dynosheet dreammaker posted... What RPM did he rev it to? Don't believe a dyno you can't see RPM on. Simple as that.
