on a mustang dyno today we did a couple of pulls.... best i got was 331whp/329wtq... i will post the chart in a sec...

 

Not bad
Your mods?

 

hmm how much boost you running? i would expect something better then that with your built motor

 

thats why its called heart breaker

anyways on thursday we are going to finish tuning it for 30psi and more timing, i am at 24 right now... i want to come back to that dyno with at least 400...

my mods are fully build motor with Treadstone Performance stage 4 kit... 5857 turbo..

 

i know if i take it to a dynojet it would b at least 380whp...

 

 

How much timing? And I assume you are running a dual tune on the car????

On BBGs car on PA's heartbreaker dyno he made basically the same whp, came out to about 360whp on a dynojet.

 

A lot lower than I was expecting.

 

i have no idea... ill do a log with hp tuners today and check...

 

and also its runing too lean.. 12.0 and at one time it spiked to 12.4.. the guy stoped the dyno and didnt want to keep going thats why i am re-tuning it on thusday with a boost controller and im going to ask vince to get more timing... it feels like it need more..

 

your intercooler looks messed up..unless my eyes are jus playing tricks

 

lol its a little sideways... i took it off and when i was putting it back my friend forgot to tight the bolt... dombass..

 

haha i thought so..but good luck on the next dyno hope it all works out for ya

 

If you think 12.0 or 12.4 is too lean, you're doing it wrong. Flat out, plain and simple..

 

wats too lean on this cars?

im didnt tune the car... it was vince

 

Too lean would be 13-13.1


With a bigger turbo you do want to run a lil richer then a stock turbo car, but not THAT rich. He seems to like to run all his cars with that same AFR.

 

wats your a/f?

 

.89 lambda or 13.0 afr on mine, stock turbo. You tune an LNF to Lambda. I've been as lean as .91 at 24 psi.

AFR is 14.7 X Lambda for gasoline. Lambda is 1.0 for stoich regardless of fuel.

 

dam thats lean... i didnt know that... good to know..

 

this dyno is a really heart breaker... i know vince told me that i was pushing 41 lb/min. so its close to 410 to the crank according to vince..

 

I wouldn't run it there on your big turbo as Nick said but .86 - .87 would be a good starting point IMO.

Vince won't go there though. Get your HPT figured out, lots of help waiting in the HPT forum.

Are you running the raised fuel pressure combo tune?

 

the numbers are a little low but it's not that low. I ran similar numbers on a mustang with my zzp kit at 20 psi and 37lb/min of airflow. mustangs tend to run 3-5% lower imo.

 

well i have to buy the credits and i have to get the trifecta/hp tuner combo from vince... i know there is a lot of help on the hpt forum and i am more exited than ever to start asking questions but im kind of affraid to do any type of tuning on my car yet.. i know what the tables are for but wat i dont get its the numbers, how you get the numbers, how to know to change the numbers to the right ones, etc... which i want to start asking questions once i get the TRF/HPT combo...

 

woooooooooooow yo bro i didnt know you lived in FL!!!!!

 

This is not a good place to start learning, just my .02. You should've started with the stock turbo!
