Default Big Wheel Stock Turbo

Has anyone swapped out the stock turbo for the Big Wheel Stock (BWS) Version (Modern Performance caries it for example)?


I am considering (per Modern)

BWS
Stage 2 waste gate
3 bar TIP and MAP
~1000cc injectors

Not too expensive


If you did this who tuned it? Yourself, Fueled by Matt, Duster 360, Syked...?

Thanks

Cool Re: Big Wheel Stock Turbo

I'm going the opposite way!

Once I get the Panel Project all cleaned up with the small details, I've got plenty of stock turbo power, but want to increase fuel efficiency.

I recently installed a Ravenworks BWS. No tune yet since I'm still stock sensors and injectors. Are you looking at MP's package deal with BWS, injectors, tuner, tune, and sensors or just buying it individually?

From what I hear is the AGP isn't a very durable BWS and going much above 20 psi will drastically reduce the life of it. Check out the enforcer BWS turbos from Forward Motion or reach out to Bob at Form and Function Performance. I don't think FFP specifically mentions BWS turbos but if you ask I'm sure he still does them, he use to work for Ravenworks.

Stay away from Turbobay and anything Mole has touched. If you ask on the SRT forums those are the two those nuthuggers will say to get.

Spend the time and do it right, don't buy used stuff off people when it comes to BWS turbos because most will be shit.

You can get away with just a rescale tune for the new sensors and injectors. Depending on your mods 1000cc is most likely overkill for your setup ATM. You can adjust parameters to your liking with a handheld if you know what you're doing but you will need datalogging capabilities.

Get a 3" O2 housing, 3" downpipe, and a wideband as well.

If you ask people's opinions they will tell you to not waste your time and money on BWS turbos, I say do whatever the hell you want.

On many forum these days that is exactly my same feelings. Members want advise but seldom listen anyway!

Originally the AGP was not balanced and is now (so the story goes). I get to keep my OEM too.

I have the Mopar Stage 2 injectors and been advised too small. So that sucks. There is a 750 and 1000cc set and up from there. I have been advised by a tuner that 330 HP at wheel is possible with BWS (seems bit high but whatever), So if you run the numbers and say 80% duty I think at almost 900cc at 58 PSI.

I don't want to get into specs for not expert. I would say MP has looked into this kit . He pointed me to one tuner, but seems like no PT GT. I don't like to here every car is different. Can you imaging Dodge/Chrysler engineer saying that to their boss when they launch a new vehicle. Seams if you have done this you would have a good starting point. Also where I live my only option is email to and fro. I gather data logs and they tweaks tune files until god knows when.

I just want to know if anyone has done this on PT and if found a tuner would use the same of OK . MP has sold out twice on those so maybe it is SRT.

Thanks

So you are going to do all this modding ...did you first do a base line Dyno run?

If not then anything about total numbers that others have done are absolutely meaningless to your engine!
Gains are about percentages %% over the starting output of each individual engine.


I do want to mention that a competent generally a trained (not self learned) and honest EFI/ECU Performance calibrator will tell you that calibrating the ECU is more about making the parts all work together and attempting to gain the best or optimum output from them. "TOONERS" will "band aid" so to say and adjust ECU's to later brag how they achieved high engine output without really doing much except attacking primarily the fueling and timing and calling it a "TOON"!

Maybe this is why many "lock" your ECU and or do not show what they actually adjust and change with that payment $$ to them for there....um....expertise!
