I hope some people are really going to be pushing this soon.
383 had chimed in that 650ish is the limit torque-wise to keep everything together and that the progressive controller is the best way to keep things in check

also on top of that has anyone played with torque management?

just something else to try and keep these things alive with alot of power.

 

well...that just theory. And its also on the safe side IMO. I have seen a few people go over 700 ft/lbs pf tq several times. Most that dis this eneded up busting a ringland. But the thing is...these 700+ ftlb setups where only putting out a modest hp # like 550 or a lil more. If I made 550 hp peak and 550 ftlbs peak you may get away with no race gas and a lil timing retard. But 550 hp with 700 ft/lbs without race gas and alot of timing retard will certainly go into detonation. Detonation is the likely culprit for those ringland failures.

Had they used a very good tune and much higher octane to ENSURE there was 0 detonation they may have been just fine.

So the limit may not really be known. I dont thing that 700 rwhp is outof the question.

The thing is you have to classify terms like "limit" and "safe". One persons definition of whats safe may be that they could spray away and still make 100k miles. Mine is that I could spray away and make the motor live for a year...lol. If I sprayed to get 700 rwhp total on a stock bottom and I raced it for 1 yearbefore it **** the bed....Id be happy about that and consider that fun and practical. Hell...maybe even 6 months. Others would be heartbroken and be put ina bad financial spot. SO skew your "safe" limit to what applies to your situation...know what I mean

I think absoltuely safe is 550 tq and 550 hp. MId level safe that is taking a chance to me is 650/650. But I think if you had the ***** and were ontop of things...a bit more may be achieveble.

 

obviously that is assuming not malfunctions occur and the tune and octane are correct for the setup.

 

Gotcha Al.
I think most people have big goals and different realities,so with that said on the average guys DD that visits the track infrequently street races infrequently,I think 650 is a sound livable #.

what do you think about meth or alcohol as a octane alternative on a "blower impaired"
vehicle?

 

I have all of my torque management set to 650lb ft. Yes progressive and/or multi stage is the way to make a stock bottom end live. I plan on mine surving 550/600 hp and about the same torque, and I mean live. I have every intention of making another 150 passes this season, as I did last season, with no breakage. At least that's my goal, but am prepared if something lets go. It's all in the tune, which includes n2o/rpm activation times, fuel, timing and all that good stuf as you know. If I was smart, on a ls6, I would add some pistons then it would live for sure, but I want to prove to myself I can do a 300hp shot over and over?

robert,

how much timing are you yanking out with TM?
do you have it setup different by gear?

 

I have it flat lined with 650 on everything everywhere, no tm messing with my runs. Timing pulled with tm, doesn't happen as far as i know with settings above your torque limit, which I am at 5xx currently.
Robert

 

that is what torque managemet does is pull timing when the limit is hit,
I use edit but I have no clue how HP works.
Edit has a table with tq. reduction by gear,Id be interested to see what tuners
has for their tables.
let me know what you can find!!

 

That's what I was saying, if you set it up and don't hit limit no timing pulled. we don't want tm interfering in any way for racing. I have every gear set at 650 also.
Robert

 

sorry I misunderstood,
does tuners have TM setup by gears?, you could set set torque at 450 or any mark that would be just above NA and pull extra timing in just 3rd and or 2nd and 3rd

 

The dynamics of TM are more complex than just pulling timing. This is not what you want to do to limit torque or to pull timing, not a tuning aid that I have heard of, as it's just to complex and not totaly understood except by GM engineers, There is a thread on this at corvetteforum going currently and i'll see if I can find it.
Robert

 

yeah I was thinking that it would be good for people running multiple stages
possibly a 3rd stage that would be maxing out the maf or SD wet setups that would not just be a nitrous tune

even NA cars seem to run a tenth or two better when a degree or two is pulled in 3rd
