desktop dyno gurus need your help..
 

i am currently building this motor a fresh 355TPI 9.4:1compression, world S/R torker heads 170cc intake runners 2.02 1.60 valves comp cam 212in 218ex .485in .495ex 112lobe sep. also adding edelbrock headers and the rest is in my sig. thanx

Keep in mind that Dyno2000 loves to give a lot of low-end torque, and assuming 700cfm, TPI, 355ci, Small-tube headers w/mufflers, and your cam with 108 intake centerline (by the way, which cam is this?), your readout is as follows:

RPM HP TQ
2000 147 387
2500 187 392
3000 226 396
3500 269 404
4000 307 403
4500 329 384
5000 337 354
5500 324 309
6000 293 256
6500 251 203

thankyou... it is a comp cam part # 08-501-8. is this close to the real world numbers or is this like within 10- 15 hp?

by the way... an MSD 6A and siameeze runners may b next the msd for sure in 3 months will this improve things??

the flow numbers for the heads r .500lift 221cfm intake ex. 166cfm at.400lift intake 205cfm ex. 156cfm

The flow numbers I used were:
.1 68/55
.2 128/104
.3 179/140
.4 205/156
.5 221/166
.6 225/170

From what I gather, these are CLOSE to the real world, but yet, when you through in variables like timing, port/polish intake, etc... who knows?

I've made both my engine thru Desktop Dyno 2000 and in the real world. The HP numbers DD gives were within 5-10 HP of the real world, while both times the torque numbers it shows were way lower than what I dynoed. It seems DD doesnt give enough torque to the TPI setup, because I can switch the intake from TPI to carb and the numbers barely change.
