on thursday i took my car to get dyno tuned at big shot dyno in hudson, oh. i must say that i am very pleased with the numbers considering what i have done to the car. here are the mods: bored .030 over, forged bottom end, lt4 hotcam kit, mildly ported stock heads with stock valves, hooker lts, bbk 58mm tb, walbro intank pump. thats it as far as performace parts go. it put down 365rwhp and 365rwtq. those numbers seem pretty good to me and everyone at the dyno said that seems high for a hotcam. you can see the graph here: http://viewmorepics.myspace.com/inde...8-dfd47305421a

let me know what you guys think!

 

that's awesome man, I've heard good things about the hotcam, always thought it was a babycam but you hear about ppl running 11s with it so pffttt track is where it counts, congrats bro

 

Link doesn't work. Nice #'s there

 

Looks about right for a hotcam with mild headwork, in good running condition. Congrats.

Dan

 

Who did the head porting?
They seem to compliment the cam very nicely

 

i had the heads ported locally at a head shop 5 years ago. it seems like they did a decent job even though i never got any before and after flow numbers.

 

Solid numbers. They're right on for your combo.

 

my combo is the excact same as your but i have a much bigger cam. I'm getting dyno results 2 weeks from friday so we can compare. i just have pcoket porting and 11:1 compression with stock size valve.

 

nice numbers man

 

nice!

 

The #'s are high because they used the STD correction factor instead of SAE, everyone goes by SAE. Get the SAE #'s by them, they will probably be 350-355rwhp. Sorry to ruin it for ya, but its better to compare apples to apples with dyno #'s. I guess I'm the only one who hates how shops to give out STD #'s so people think they have "freaks".

 

werd. i remember i was at the dyno..and this one one guy with an 03 cobra got like 430 hp STD. and he kept complaining because last year he got 450 STD..so he couldnt figure out why his #'s were so much different.

 

Fixed it for ya.

 

STP (STD) corrections are typically 4% higher than SAE corrections.
This makes the conversion very simple:

SAE = STD * 0.96

Background Info:

SAE (Society of Automotive Engineers), USA. Power is corrected to reference conditions of 29.23 InHg (99 kPa) of dry air and 77 F (25 C). This SAE standard requires a correction for friction torque. 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.

 

damn look at that torque! talk about a flat line
