New dyno numbers: 294 rwhp
I just waiting for UpRev to get some time available on their dyno to finish tuning and get some current dyno numbers. I may go to the SAR this Friday but not 100% sure yet.

Kudos on the build up Rednezz. I would point out ( and correct me if am wrong) but those are dynojet engine graphs which usually run a little higher than DynoDynamics

impressive. My plan has always been to try to take the car as far as possible NA. My bolt on power mods are tne Nismo CAI, Nismo Exhaust, MD 5/16th Spacer, Nismo Headers, Berk Metallic HFCs. The plan is to pick up some AMS racing pullies, Nismo camshafts and tune w/ U-tec.
I'm not exactly sure where I'll end up but I really enjoy the pursuit of squeezing everything out possible.
Well done.

STD numbers are not always higher, it depends on ambient conditions, most namely, humidity. My STD numbers are typically LOWER than my SAE values. This is because I live in the desert, 8 -12% RH is common almost year 'round.

Friction torque can be determined by measurements on special motoring dynamometers (which is only practical in research environments) or can be estimated. When estimates must be used, the SAE standard uses a default Mechanical Efficiency (ME) value of 85%. This is approximately correct at peak torque but not at other engine operating speeds. Some dynamometer systems use the SAE correction factor for atmospheric conditions but do not take mechanical efficiency into consideration at all (i.e. they assume a ME of 100%).
STD or STP. Another power correction standard determined by the SAE. This standard has been stable for a long time and is widely used in the performance industry. Power is corrected to reference conditions of 29.92 InHg (103.3 kPa) of dry air and 60 F (15.5°C). Because the reference conditions include higher pressure and cooler air than the SAE standard, these corrected power numbers will always be about 4 % higher than the SAE power numbers. Friction torque is handled in the same way as in the SAE standard.
ECE (European Community), Europe. The ECE standard is based on the European Directives. Power is corrected to reference conditions of 99 kPa (29.23 InHg) of dry air and 25°C (77 F). Friction torque is not taken into consideration at all.
DIN (Deutsche Industrie Norm), Germany .
The DIN standard is determined by the German automotive industry. Power is corrected to reference conditions of 101.3 kPa (29.33 InHg) of dry air and 20°C (68 F). With the advent of European legislation and standards, national standards such as the DIN (formerly widely used) are now less significant.
Actual You may see this on some charts. What this means is this is the actual horsepower archived on the day tested and no correction factor has been applied. One can assume better or worse results with varying weather conditions.

Looks like the headers on the Cosworth motor look very similiar to the Nismo headers. My problem is the intake manifold. After 6300 rpm I just don't have enough air. I really wish I had a Cosworth intake manifold or anything better than I have now so I can take full advantage of my heads and cams. I'm sure I can pick up another 10+ rwhp.




I would love to see your track numbers. Let me know if you ever come up to Ennis I would love to run against you.
