383, AFR heads, HSR, BRE cam dyno'd
http://media.putfile.com/383-Stealth-Ram-dyno-run
not bad but not what i was hoping for/expecting. i wanted over 400 and near 400 torque but i got 392/371 but it was HOT. car was heatsoaked for sure. drove there and strapped up immediately. Temps in the dyno facility were reading high 80's i bet. it says 94 on the graph but i dont think it was that hot.
Either way my 10th and last pull put up most hp but suffereda little hp loss inthe mid lower range since it was hot i bet at over 200 degrees. torque was down too but it will be back up once cooled off
best torque run was 371 and flat as kansas...from 3700 ish to 5000 its over 350lbft. this was at a better 184 degree coolant run so it shows heat is hurting me
FIRST PULL at 180 degrees was about what i had in the car when i ran 11.6 at 116 in the heat. This was approximately 375-380whp as i had more timing than this run on the chart that made 388 or w/e. I had 38-39 degrees compared to 34 on that run. I tried 36-38 and 34 it liked the best. Torque was low on that run, althought peaked at 365 at 5000rpm, it was WELL BELOW that below 4500 or so. IT WAS LEAN at over 16.5 to 1. Took 5-6 pulls to fatten that up right and it showed by holding a nice flat torque curve down below 4000 from 4000-5000. really picked up in the midrange, probly 30 lbft in some low spots. Really is gonna help the car.
Although hp didnt go up much and partially by the heat soaked runs, i did gain hp down low and thru the upper mid range from 5000-6000. More area to the curve.
BUT most of all i think the power is alittle lower than it should be for a setup like this. I think it may be due to the TPI air intake and MAF size. 3" and that TPI ducting is not flow friendly. 700-750 cfm max i think when i need 1100
So next mods will be a custom MAF and air intake setup probly 3.5" total
With those mods and cooler temps, i'm HOPEING for near 415-420whp and 380-390 wtq but the car runs strong. Cant wait to see how it does with the new tune at the track. should really pick up in the 1/8 and lead to better 1/4 times. hope for 11.4's at 118
