G'day, Street Tuna...

Thanks for the power conversions. Just curious, when you're talking with the other car guys down there do you go with Nm and kW or lb/ft and HP?

 

It really depends. Some guys are HP and ft/lb only. Others (generally the younger 'metric' generation are Kw and Nm.
The conversion is easy. 1kw = 1.34hp, 1Nm = 0.74ft/lb
Hope that helps.

 

Ahhhh, I see how to use this... you wanna impress someone with HP, forget metric.

But for torque, I'm gonna start talkin' Newton-meters.

Even though it brings back bad memories of physics class.

 

my boy RICE-ETR made 638rw today, stock bottom, like 85k miles, pump gas and meth, stock heads too.

 

Anyone tried running 650+ rwhp with 100 unleaded and meth? I haven't heard of anyone blowing up on race gas.

Update: 630rwhp 609rwtq (Mustang Dyno) on the stock bottom end.

 

Mines surviving so far with 475hp, but I thing that the tq will get me before the hp. I am already making 606tq on 163k mile motor. I'll keep squeezing. Hopefully it want pop.

 

Just dynoed 561rwhp.. 541rwtq having to shut down at 5900. Need more pump... adding a new pump and another * of timing we are anticipation 580-590rwhp. Stock bottom end with custom cam though.

 

Update... Still running strong at 603rwhp and 506trq!

 

See my sig for my Z06 Blown by ECS D1SC and installed and tuned by FLP. The secret is a great complete kit, install and TUNE is HUGE of course. I have detuned myself to live as long as possible on my 100% stock LS6 motor, and am shortshifting a bit on the street so i don't exeed 8 lbs or so on my 10:5 to 1 LS6 motor, and am probalby seeing around 550rwhp on the street.

When a new C6 Z pulls up to me or i go to the track, then its time to crank her up to about 6500 rpms and 10 to 12 lbs of boost!! I have 3400 flawless miles so far and i don't FLOG my set up as its a daily nice weather driver and i am hoping to get at least 20K miles out of my stock LS6 motor!! How hard you drive the car is HUGE as to how long it will last obviously!! I am also running straight alky methanol injection as a safety mearue and not to make more power, but to run as safe as possible, as i rather run rich (and be down a little down on power) than grenading my motor, etc!!

 

Mine is still running strong at 10,000 with no problems. But like you said, it all depends on how hard you push it. a couple of months ago, I had to push it to limit when I raced Lamborghini Gallardo on the freeway. Had him up to 160mph before we let off.

 

I lost my bottom end finally, it started knocking. The final nail in the coffin was making a pass when I didn't realize that I was over 1.5qts low on oil. It was on it's way out though for a while looking at the debri in the pan. Way more debri than the litte tick mine had would produce. The likely culprit was rod bolt stretch. I was running it to 6500+ all the time for 15k miles under boost.

My suggestion is to keep the RPMs low if possible, or replace the rod bolts.

 

i am running around 530hp and over 600 ft/lb of torque with nitrous...switching over to a turbo soon =)

 

well we will see how my car holds up lol all stock bottom end running 5 psi on an p1sc and gonna run a 50 shot i am hoping for 530 or so. what kind of cylinder pressure is that? but i have a good amount of sopporting mods. an whole upgraded fuel system from the tank to the rails, with an fpr and an booster pump. my 12 bolt should be in soon im excited but also a lil shaky woundering how healthy my car will be lol .....

 

sounds like your doing it right to me.

 

Why not just run 8# of boost and not complicate things with the Nos.
Have the 530 all the time.

 

I just upgraded the trans to a stage4 FLT and uped the boost to 13lbs. Now making 518rwhp and 653rwtq. Going back to the dyno soon to do more tweeking because the computer wouldnt connect to the truck and allow me to adjust the tune.

 

Im still runni strong as hell. I have 5* less timin in it now then when i made 661hp 650tq but otherwise teh same boost and all. Its fun and lemme tell ya NOONE drives harder then me. Im ALWAYS on it. Ill be sad the day it ***** the bed. GL everyone with crazy power!!

so do you guys think i can just shoot the 100 shot and make it through a few track runs or would that be a bad idea? i really want this motor to last untill fall so i can pull and build it??? anyone?

 

It's all in the tune, no tune, motor go boom.

Oh yeah, run good gas if you are gonna do it, and by good i mean the leaded stuff of at least 110 octane. Safety first.
