What makes 180rwhp? My stock turbo skyline was making 193rwkw on 12psi and is a very quick car. How much does the M3 weigh? It is a fairly big car. Both my skylines produced more torque also. In that graph that V8 is making 259ft pounds of torque. My old skyline made close to 320ft pounds and the current one is pushing more than 500ft pounds. I'm sitting on about 700nm and that is out of a small 2.5L 1.3 ton car. And I don't just peak that torque

Stock R33 GTSTs make around 180rwhp. They run 7psi, smic etc.

M3 E36 Evo is 1500kg. R33 GTSTs are 1390kg, so yeah, 110kg less.

E92 M3 is 1620kg.

700nm of torque? lol. Merc C63 AMG BLACK has 630NM.

Yeah. Dyno torque readouts, unless setup properly, are usually completely worthless since the figures are way out.

exactly. i've seen plenty of dyno readouts from small cars that are higher than the quoted figures for v8's and things like the xr6t. there's no way a 2.5L turbo 6 making under 200rwkw is making 30% more torque than a 4.0L turbo 6 that makes 270kw at the fly.

a rb25 making around 200kw would probably be making no more than 400nm at a guess, probably less though.

Yeah you aren't making 700nm of torque.

I exaggerated a little, its closer to 670nm.

What good is a dyno if it can't read proper figures? No one can tell me there is going to be a massive difference from the readout to an actual engine figure. If this is the case, why is the kw or hp anything to go by?. It was on dyno with two people in the car and about 50 - 60kg of led in the boot, two straps holding it underneath and still we were losing traction on the dyno. Tao made close to 600nm on with the same turbo in his car on a hub dyno.

I'm making about 300rwkw.

It’s because the dyno operator rarely dials in the gear ratio/final drive/wheel diameter etc, I've had the same argument with actual tuners before, yarning about excessive torque figures.

But if you get the RPM at which you make the peak torque figure and get the power figure at that point (using the graph) then use the equation [Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)] that will give you your actual torque figure at the wheels.

Or just use this calculator;

530nm according to that calculator. According to my dyno sheet my tractive force is 1340 lb or something at 132mph.

And just because that AMG has that much torque doesn't mean shit. There are a bucket loads of cars which will deal out more power than that mercedes for no where near the price they ask for that car. What is your point? My brothers rotor makes close to 900rwhp cost 30k. You can get a 2jz spend some money on it and get massive power and torque. Doesn't mean shit when you point out the amg.

If the above calculator is right then cool, my car is only down 100nm of torque and doesn't have a engine which probably weighs more than my car.

i believe they are abit of a boat, but in all honesty, change suspension and do ur part in getting it stiffer then that will be gone. then powerrrrr it ;)

As for the camry yeah dw about what he said, u like ur car then dont worry about what people say

However, Aurions is the new model up from the avalon, and is completly different to the camry in power, looks sorta similar, dont misjudge who to run haha, cus aurions are machines

LOL... WAT?

If the engine gets heavier, the car gets heavier... Secondly, the RB engines are f**kING HEAVY!!! My engine that is more then twice the size of the RB25 is around 50KG lighter...

Bloody cast iron crap.

      Mistakes were made, my R34 Story

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      By HYBRID VL · Posted

      im sure mine stays in gear and wont shift unless i shift it? and for sure it wont go back to Auto mode if its put in manual mode? if i use paddles but its still in D then of course it goes back to auto mode. but yer if its in -+ and i use paddles it will not auto change gears what so ever and i have tried this. it will gear down if at a stop though which is kinda nice but goes back to 1st gear not D. i think it used to be like this with imports aswell i dunno if its really like it anymore like when i got my R33 it had alot of JDM options which local cars didnt have. Now local cars have kinda caught up even the lower models. but yer transfer rates and other things makes it almost on par.

      Very decent bit of kit. Definitely black it out I reckon.

      PRP RB26 cast block + head prototype running

      By r32-25t · Posted

      Because people who want that are buying euros. The people with the money to buy the aftermarket heads and blocks aren’t interested in efficiency or making -7 power, they’re making well over 1,000hp and pretty much only drive them at full throttle  best way to way make money is know your customer base and what they want and don’t spend money making things they don’t want.

      It's not, but it does feel like a bit of a missed opportunity regardless. For example, what if the cylinder head was redesigned to fit a GDI fuel system? It's worth like two full points of compression ratio when looking at modern GDI turbo vs PFI turbo. I'm pretty reliably surprised at how much less turbo it takes to make similar power out of a modern engine vs something like an RB26. Something with roughly the same dimensions as a -7 on an S55 is making absolutely silly power numbers compared to an RB26. I know there's a ton of power loss from things like high tension rings, high viscosity oil, clutch fan, AWD standby loss, etc but it's something like 700 whp in an F80 M3 vs 400 whp in an R33 GTR. The stock TF035HL4W turbos in an F80 M3 are really rather dinky little things and that's enough to get 400 whp at 18 psi. This just seems unwise no? I thought the general approach is if you aren't knock limited the MFB50 should be held constant through the RPM range. So more timing with RPM, but less timing with more cylinder filling. A VE-based table should accordingly inverse the VE curve of the engine.
