I made a pretty safe 735 rwhp and 666 rwtq on pump fuel only. It probably would have made more, but I had to back off the timing to get a smooth run. The dyno kept going daft.

That was only taking it to 6000rpm, where it was making 15psi.

I do use meth now, but Ive never been on a dyno with the meth working.

 

833rwhp/828rwtq on 91 oct no meth. that was on 13.5 lbs too.

 

833rwhp on 13.5 lbs.. that would be nice

 

~850 rwhp on 12 psi, 347, 93 octane, half *** tuned.

 

Let's see some mph passes from the 800rwhp+ guys.

 

I really dont push it on pump gas.... 93 here... i have it set at 13 psi and i keep it there...... Ive seen what happens to cars that try and push the mark on pump and sooner or later they all go the same way...... something goes and man does it go big...... in my eyes when i add more boost its simple to think thise way...... is it worth it to risk a $6K+ Motor and a $1900 Turbo on crappy gas or just add $40 worth of race gas..... alot of people have learned from others mistakes.
bad *** numbers are awsome on Pump Gas but i guess what im trying to say is its not for me.

I see a lot of cars on Dyno's do the numbers then fall short when pressed in a situation that doesnt offer an open hood with a fan blowing over the motor.

And then those that say they have 93 but spike the fuel system. To me if a car can make 1000 RWHP.. it makes 1000 RWHP. If you have to turn it down to be able and hammer on it.. so be it. But when your leaving a lot on the table power wise.. why? Guess for novelty on a dyno

Its like the athlete with or without steroids.. if he can bench 500 lbs.. he benches 500. Make sense? You weigh 120 lbs.. have a goal to hit 500 lbs.. you do whatever it takes to get your goals If you have to take viagra.. end of the day you'll be remembered for the lift.. not that you can do 370 without.

Careful how you play with low octane on a boosted engine.. i'm with Kyle

 

Im the oppisite...... never had the car on the rollers to see what she makes HP wise... 10.07@135 with the 13psi setting speaks for its self.... 20 psi did the same

 

I'm not at 800rwhp yet ( at least, not proven, although I may be close with the meth )

As it stands, my traps aint too bad.

 

Provided my new rear tires come in time, I am going to the track this weekend. Then the next week I am going to make a run on the dyno to see what my current power level is on the dyno to compare to my trap speed. My guess is about 145 mph traps and 800-825 rwhp. I guess I will find out soon.

 

I don't know if I should be happy or upset that I ran 143 mph in 90+ deg air at 3750 lb, but only made 680 rwhp. There seems to be alot of guys running 14X mph with 200 rwhp more than me.

 

We've got a bit north of 490rwhp on a bolt on LS1 with a STS kit @ 7psi on 93 octane

 

91 octane here, numbers in sig. I always wonder what it might do with 101...

 

I trapped 145mph with 680rwhp and using race gas. I would assume a heavier car with more power will end up trapping 145mph or more.

 

I'm running 15lbs, maxed out my weldon 600a.... 800 rwhp+/-

 

13psi with no meth, dyno said it made about 400 rwhp, car trapped 122mph @ 3800lbs

Dyno's are about the worst way to compare one car to another, especially when everyone uses a different dyno on a different day in a different location.

I've seen several 700+ rwhp 6spd cars at the track that don't ET or MPH as well as my 425 RWHP car does.

One day I made 475 rwhp @ 10psi on one dyno, then another day I made 425 RWHP on another dyno @ 16psi

A dyno is for tuning and that is about all they should be used for. A dyno only needs to be consistant, not accurate, it could measure in garflabs for all I care as long as I know i'm getting more or less garflabs when I make a change on the car.

 

Nice way of puting it !

 

15 psi 820+rwhp 800tq (93 **** gas) to be more precise I have run it this way all year without one issue other then nearly killing myself more then once
Most here seem to forget if you do your timing correctly and dont go overboard its plenty safe. Im way down on power because of my 14 degrees

 

The car hasn't seen the dyno since the TTi 80mm race kit went on it. The best pump gas pass this year was a 10.2s at 136mph. I drove it to the track and ran it on MT DRs with Sunoco 94 octane, no ice, no meth, 17 degrees of timing and 14psi. The car is probably 3650lbs at this point.

Just for fun add a meth kit + boost + timing and go for the 1000rwhp dyno sheet! If it blows... its winter, your due for another setup anyway
