Car dynoed 348rwhp/361rwtq on a dynojet with the stall locked

This car is going to be my summer "nice day" daily. Overall, I am very pleased with the cars power & the way it puts it to the ground. I would like to thank Mike Norris for getting me in for the tune. Mike is a well-respected LSX tuner & Tech sponsor(I believe) but he does it all. While picking his brain, Mike told me the highest hp bolt-on LS1 to cross his dyno was a M6 car similar mods to my A4 in addition to a Fast 92/92 setup and crank pulley. It put down 365rwhp. I just say that because all dynos are a little different & I wanted to reference that for myself and you guys.

Future plans for the car right now are just a BMR tubular k-member and a ATI balancer. Other than that I am pretty much done putting more money in it for a while. Thanks for reading and let me know what you guys think!

The final dyno pull.


Here is the graph and some car pics:

 

Those are great numbers for a stalled auto. Will be interesting to see what it does at the track

 

Thanks! It feels really strong most likely due to only having 70k on the clock. I may not make it out to the track until next spring or fall even tho we have a nice local quarter mile track. Like I said I plan on it being a nice daily but when I do hit the track hoping for a 11.9x pass with a tubular k, crank pulley, & better tire.

 

11.9 might be tough without some weight reduction. Tough but possibly doable

 

Yeah, I think it will be close also, the tubular k will help. I weight only 130lbs. so theres that lol

 

Lighter rims will help. 11.9 is certainly possible. It's all in the 60'. You need to get a good 60' to hit 11.9 at your current power level.

 

Agreed. For that kind of pass do you think I'm looking at a minimum of 1.7-1.75 60' with about a 112-113 trap needed? That's kind of my assumption with everything I have read.

 

That's a strong and well sorted car that will surprise some pretty fast new cars. LS motors LOVE good exhaust. Nice work!

 

A4's put down around the same power as a M6 when you lock the converter.

Nice numbers OP.

 

Never knew that. I know my buddy put down like 325 rwhp with full bolt ons and a 3500 stall. Stock he dynoed 300 rwhp on the same exact dyno. I assume the converter wasn't locked in that run

 

You can tell by looking at the graph and there will be a big tq spike around the stall speed if its unlocked. Locked and the pull will look like a M6 with no converter slip.

 

Not bad. You could push that up to 375 yet too

 

Nice numbers OP! Like what was said above a lite wheel and soft tire with good air will probably get you a 11.9 your looking for.There's still a lot of bolt ons you could do as well. Just depends on how far you want to take it.

 

Thanks! Yes, the old LS1 is still very effective with todays aftermarket for them. The goal all along has been for my car to be competitive for the newer stuff coming out with my motor still having its factory seal.

 

Thanks king!

 

Yeah I would assume the stall wasn't locked. The dyno could've also been a lower reading dyno. Maybe both. 300rwhp stock tho is good!

 

Thanks hammer! I think so too. My car was actually motivated by your threads to not reach for the cam. Right now I'm in savings mode because you know how expensive it gets out there lol

 

Actually the dyno turns out very typical numbers for a dynojet dyno, but from 300 bone stock to 325 with full bolts and stall on the same dyno was a bit surprising. Having it unlocked must make a huge difference

 

Thanks! We'll be close if not there with wheels and a good tire IMO!

 

Yeah everyone says the stall eats up dyno #s like crazy. That's why one of the first things I asked my tuner was will the stall be locked or unlocked. Because, I didn't want to look at the graph and feel instant disappointment lol he told me he always locks them.
