k heres the beginning of the story:

worked on it today again, pulled the entire valvetrain off it, cuz its a solid flat tappet only. so we needed reduced spring pressure on the break in procedure, so after we fired the beast, which sounds like sex i might add hahaha. we pulled the valvetrain again to install the inner spring after. then fired her to make some noise.thing just rips like a banshee. revs like a mother.

out of the box carb didnt touch anything. no tune in the motor either. we got 2 3/4 passes on the car. the carb is only getting 90% throttle, we gotta figure out the bracket. we ran it on 94 octane for break in and these passes, believe it or not its rammed at 39 degrees timing right now with the power its at. best part is we cut it at 7000rpm and the numbers were still climbing. and even funnier is we made it on a "cold" motor. only ran 130deg on water and 90 degrees on oil. so cold for the power. gonna jet, tune, run it to 7500rpm and run it hotter and it should pick up 10-15hp. then ill spray it i think. that motor is an easy 550+hp magazine number motor, stupid superflows. not bad. now its time to see how real the power is in the car



oh i almost forgot 3/4 pull to 7000rpm only made 510hp at 7000rpm (more unknown yet) and 450lbft with 400+ from 3500-6500rpm only got couple passes on it, from all the work on it and break in work. more to come soon. just thought id let you guys in on the prelimary results.

 

Congrats, thats on an engine dyno or chassi dyno? Are those RWHP or fly wheel HP?

Either way thats pimp.

 

I wouldn't be flooring it at only 130° water temp.

 

engine dyno

 

definately more power in it at operating temp but 130 is safe, and thats after the motor was running for 10 min lol stupid CSI sweet water pumps lol. ill have more numbers today, gonna get the motor up to 7500rpm, its still making power at 7k and thats where we stopped. tune it and giver another shot. plus im gonna spray it after. im confident on SNK chassis dyno it can be tuned to a 440-450rwhp n/a. ill do that later on

 

Nice numbers Jason! Might be good for tens with GOOD traction.

 

what was the AFR untuned ?? congrats man !! lets put on some accessories and do a chasis dyno now

 

I have a feeling that his 5000rpm/T350 stall will make for less than accurate RWHP numbers. I WANT TRACK TIMES!

 

yea it was untuned out of the box carb, running fat. cant get the temp up due tothe 94 octane starts to detonate at 7000rpm+ we only made a pull up to 7k and the power was still climbing. so with some tuning there is easily another 10-15hp there.

 

5000rpm t400 im still gonna try rwhp it will be off but what the hell just for fun. its got ladderbars and coilovers, should pop some air on the fronts pretty decent with the tq band its got. cant wait to get it closer to completion. ill have some more numbers posted soon

 

I don't understand what you mean by less then accurate RWHP, RWHP will be what it will be, there is not such thing as less then accurate RWHP, it is what it is, it's like me saying my 12 bolt makes less then accurate HP, it doesn't, my RWHP is what it is with the 12 bolt and thats all there is to it, if you think like that then you might as well say less then accruate HP with a transmission rather then a a DS hooked up to the flywheel and then to the wheels.

RWTQ may not be accurate because of the stall but the HP still is, HP is a calculation of everything.

 

actually hp is nothing, there is no way to measure hp. hp is derived from tq. physics is physics.and what hes talking about i think is the fact of the converter it will flash and tear the tires off the back of the car. its pretty hard to eliminate tirespin in a situation like that. also i would hit the 150 shot on the dyno too which wouldnt help much in the situation

 

Thats why I said TQ will be off HP won't because your your TC will not stay flashed so you'll get an accurate number, it will just be a very small dyno graph but you still get an accurate HP number becaues you peak at 7k RPM and your TC is above it's stall by that time so your peak HP number wil be accurate.

 

actually i dont know where peak is yet lol we tested to 7k and it was still climbing i figure it will peak at 7500

 

well on this conservative dyno the tale is told ran the motor n/a past 7000rpm. liked 38 degrees and wants to keep going. made peak power at 7200rpm 520hp 450lbft at 5100rpm. ad 5% to compare to other engine dyno numbers for correction. ran well, started to drop off at 7500rpm, so no need to go beyond that. now for the juicy part

jetted the plate to a 150 shot, ran about 8.5psi fuel pressure, c12 race gas. unfortunately the bottle pressure started at 800psi and was dropping fast. by the end of the first pass it was 750psi and we tried a second one but it was down 20hp across the band due to it being so low. thing ran flawless, clean plugs n/a was alot fatter on the sauce,m but hey, i had to work with what i got. didnt have a bottle heater and it was half full to begin with. anyhow enough with it, keep in mind too this is all through exhaust. no open headers on it yet. on the first and only nitrous pull it made 700hp at 7000rpm and 650 lbft at 4700rpm! not bad out of a fat conservative nitrous run, 350 cid and a non roller motor. flat tappet baby!! 11.5:1 compression. im happy with the results, there is room to wick it up for sure, plenty of hp there, just got to go play with it and have some fun now w00t!!!!!
