** Precision 6266 meets E85 **
 

Well the time came and went, last night we went round 2 of our tuning session after having some fuel restrictions last week. Off the trailer the car made 498whp 360ft lbs at 22ish psi. the regulator was jumping when in boost but that was fixed with running direct power via a relay to the pump.

Pull after pull we finally get the A/F where it needed to be and started with timing. The more we gave it the more she wanted. After a ton of pulls the car wasn’t improving and was settling at 530whp. We scratched our heads thinking why so down on power.

We started looking everything over and re-routed the boost controller and then boost came on better with the ramp up, so then proceeded to clean up those cells in the fuel table. Then realized that during the whole pull the motor is only seeing 22-25psi from 5500-7800k rpm then hitting 28 from 7800-8k RPM.

We figured lets crank it up to a steady 28-30psi on the pull and let it hit peak boost at peak RPM. And what do you know with a 2psi increase on the controller she shot to 590whp the very next pull then back it with a 595. Overall it went well, the 6266 wants more rpm and more boost but I cant give it anymore as I feel we have pushed the max the stock head will give without having to add NOS.

So there you have it 595whp 424ft lbs @33psi

My girl for my 6266 bday gift love you

Reggie @ OSR tuning for working the keys and unleashing the power.

Bisi @ Bisimoto for the AEM EMS

Rick @ Keke fab

Manny @ Clockwork performance

Now just need to wrap up the little things like securing the ecu , connecting the master cutoff switch and the line lock and shes ready to rock and roll. Passes @ Irwindale coming this month

Good lord! This is exactly why I want to go turbo with my track cars!

Good numbers, could we get a better pic of the dyno sheet to see the rpm's?

What kind of timing?

congrats, great numbers!

I'll get a better pic later today of the graph.
Thank you guys

Details on timing and engine build please!

E85 6266 sr20det - YouTube

Engine build is simple
.20 over wiseco
Eagle Rods
Stock head with BC springs, BC 272's, rocker stoppers stock throttle body.
Head is holding us back.
Peak timing up too is 30degrees and seeing as much as 35 when ramping up

wow almost changed my mind about going rb , nice work

Sucks that we don't have e85 here in Hawaii. I'd love to put out numbers like that.

If you want a bling factor go rb but I wouldn't waste my $ on it personally

Can't see the rpms.....

glad to see the numbers come up after i left.surppised for stock head...e85 works!speedshop osr those guys know there stuff.....i like the 6266....i think time to replace the 35r....are you going to go to water cooled inter cooler also? ..i have the pump...and i might have a q45 throttle body let me know...paul...

im torn between rb25 or s14sr in my 13

Ya paul we figured out what the issue was and that wasnt till the last 2 pulls then the cop came, Reggie will tell you about it.
yes i will be going water to air and a Q45 TB as well. head as stock as can be i wish it was ported as we would have seen a lot more out of it.
i think with the ported head , Q45 Tb and water to air we would be close to if not over [email protected] the same boost levels if not less

RB is over priced for what it is, if you want to go 6cyl go 2JZ

yea reggie told me..i think once you go solid lifter with port and polish,700 def possible...will be a monster...got me motivated to get my vvl 2.2 done...

VVL would be nice but too much $ for me cant be baller like you guys. i got a bare head that im going to clean up the ports on at home, I already have solid lifters too would just need valves/guides/springs

2j is nice but its more then rb from what ive seen

2jz-ge can be had out of Lexus's in the junkyard all day for cheap.
NA-T's are just as good

yeah thats true but i think u may have changed my mind for s14sr

Congrats, very impressive!

Thank you, good power can be made with the right combo of parts

what is the car for? highway monster? dyno queen? drag? or all? which would make it a monster drag queen i guess, lol. but seriously.

It is a street at set up for drag and anything that wants to pull along side me lol

damn, those videos :O Bossssss

What transmission are you using?

It's a z32 trans

Damn glad to see this....been looking to see how much I can push mine...

woa nice numbers

Thanx guys

well I never got a clean pass but I did learn a lot about the car.
Line lock and 2 step will be set up next
