Welcome me to 500hp club!!! bw s259

[keltalon]

Went to the dyno today with new injectors and intercooler and made some very good numbers with the bw 259. 504.2hp 472.5tq the car rocks dynoed the car full tank e85 @30psi. I will post a log later! The power is certainly in the dover cylinder head!

Wow I bet your car is completely uncontrollable from 4k-4.5k, 150hp/tq jump! That's insane.

 

[TofastForU_99]

yah that looks pretty crazy. now you need to change your profiles wish list that says you want 450HP

you just dont know! Its insane from 4000rpm to freakin redline. The car pulls like no other car i have ever owned. I tried to do a 70 to 90 but all the car does is spin. I think the road to 500whp has been a journey and I have enjoyed every bit of it

Update those dyno numbers!
And I can't wait to get my BW.

sounds like some nice numbers,what fuel set up are you running?

pte 1200cc injectors
rewired walbro 255
controlled by dsmlink


here's my log egt's maxed out at 1550 degrees,

Damn, that turbo ramps up real fast and good spool for what its capable of.
Great numbers!

Must be the hks 264 cams Can't really say. All i can say is the turbo hits hard! check out this log I did this morning. After the log I said you know what I need to hit the dyno today spinning in 3rd and 4th!

 

[dsmmatt28]

I told you!!! Congrats... Now I need to go I will be going back for another shot at the title soon. With the new mods.

You wouldn't believe what was holding the turbo back my exhaust system was too restrictive so we reworked it and ! I ran a very conservative timing curve didn't won't to risk breaking something. I can say that the turbo does have a whole lot left in it

 

[dsmmatt28]

It does. Wait tell you turn it up to 35psi. Ask me how I know. What are your IDCs? Im running twin wally in tank set up. With the Blue Max I was seeing around 71%-75% IDc @30psi

Someone wanna give me the quick meaning of IDC?
Thanks. Just want to follow along with how this BW is tuned for future plans.

75% to 80%@30psi

Injector Duty Cycle.It is a measure of how hard your injectors are working. If they are 100% they are maxed out. Typically you dont want to run your injectors past 80-85% injector duty cycle. Im sure plenty of us including my self have went way past 95% IDCs.

 

[dsmmatt28]

75% to 80%@30psi

Yeah thats were mine is about I havent seen it past 75% yet. Im one the 1250cc BM.

 

[dsmmatt28]

Those 264s really let it hit hard. Please tell me you got some vids???

No I didn't plan on the dyno today. I was in the area and just decided to stop and do it. We did't tune the car or anything just strapped it down and ran it with no adjustments what so ever.

 

[dsmmatt28]

Its running good. What the timing looking like? I dont have dsm link so I can view the logs.

Good numbers but theres alot of problems I see with your log, specially the fuel trims. They need alot of work! Also you have alot of room for improvement with the timing numbers, specially "under the curve", you can easily make the turbo spool quicker by adding more peak timing from the 4k-5k area, this will net more hp, and higher tq numbers. Also im assuming your using a maf-t and gm maf, goto misc tab. on dsmlink (ecu/logfile) and check the ignore iat/baro, this must be done when converting to a gm maf-t setup. Use Jeffgst.com page to reference on how to dial in fuel trims, the car WILL RUN MUCH BETTER. Good numbers, theres alot more left in it!

Way to go that's super!
Could you describe what change you made in the exhaust system - before and after?

Looks like about 240 whp already at 4000 rpm - that's unreal for a turbo that big on a 2 liter. It is still a 2 liter isn't it? Must be those 264 cams.
Guess I'll have to install dsmLink V2 so I can read your logs. Or else you could go buy V3 - that would be much easier!

Airflow readings will be off from an improperly tuned airflow sliders (which is evident). Once he gets that dialed in the car will be near perfect and logs should be looking alot better.

Thanks for the tips! I am still using stock mas. I will be putting the airflow sliders back to zero to see if i can try and bring my fuel trims back inline.

Yeah still a 2 liter Yeah tuning needs to be tweaked. v2 will eventually will be replace. As far as the exhaust is concerned we totally took the old exhaust off and professionally remade it. No cat The old exhaust was done by a shade tree buddy of mine the pipes came together very poorly hurting performance badly.
