Just got back from our local dyno day. Did 4 pulls without any changes. First two pulls didn't come up right because the tach on the Dyno wasn't reading my RPM's right. (showed 10K RPMS when mine showed 6K)

Mods:

95.5 Series II motor

3" turbo back exhaust with 3" O2 sensor housing

Cone Air filter

Removed mechanical fan

10 psi of boost

stock SMIC. STock Turbo, stock ECU

HP 230

TQ 290!!???

The dyno charts are being emailed to me. Once I get them I will upload them. They are grahped with HP vs Speed rather then RPM. The pulles where done in 3rd gear. I have an R33 4:11 rear end. Why is my TQ so high and HP so low?

230hp, if at the wheels is around 170kw and not too bad for the mods you have. The engine makes 250bhp stock.

sorry I am not too familiar with torque in ftlbs, so I really cant comment on that one:) Just remeber though, that if you run in a lower gear than 4th, there is greater mechanical advantage. Torque, being a function of power and rpm, will therefore be higher - dont know if you took that into account?

how come you didn't say the same thing you did on NICO ?

"first 2 runs where messed up because my tach signal wouldn't show up on the dyno since my stock tach doen't work and I was looking at the dyno's tach I let off early...as a resault it showed I put down 290 ft/tq but the last two pulls I used my speedo to and let off at 145 KM

The car put down 230 WHP and 145 ft/tq. The power curve is very broad and flat. A/F ratio on the top end are 10.5:1 and it lower. I have the dyno charts on my computer but I can only veiw them with a dnyojet runviewer any idea how to post them?

There was a sentra with a GTi-R motor with a FMIC T28 turbo 15 psi put down 258HP 255 ft/tq"

I posted here first without seeing my dyno charts. They where emailed to me later that night so I was going off what I was told by the crowd of people there watching us dyno. After looking at my dyno charts I would say my car is making S2000 power. :Oops:

Hi guys, torque is at the rollers, so it has gearbox (third gear) and diff ratio multiplication issues. Don't try and extraploate the number, the formulas will make you brain ache, just look at the shape of the curve and where it makes torque, not the absolute number itself.

Hope that helps

    • I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.
    • My Nismo 1.5 churps a bit on reverse turns when cold, but besides that feels like a stock diff.
    • Yes, but, I paid cash and I'm pretty sure the receipt was in the bin 10 minutes after I got home Note to self, keep all receipts
    • Bunnings would have just handed you your money back on that one!
    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
