Turbo BS Thread

I cannot understate how smooth my afr's are now with that on. HUGE HUGE HUGE difference! It use to jump around on me quite a bit throughout the rpm range. Now pulls are super smooth afr wise. I'm steady between 11ish to 11.9ish depending on rpm. And I can pull after pull and it stays consistent at 11.5ish. That is INSANE again. Everyone that has a turbo has to do this I'm serious........the heat soak that it prevents is phenomenal. I noticed how hot my charge pipes were not just now but for a long time of monitoring them. And i mean very hot. I thought about wrapping them some time ago. I also saw someone did it recently. Again it is absolutely mandatory imo to do this. The heat soak it prevents is incredible.

@GioGuitarDude have you done this? I know you measure your IAT's and I'd be curious to see if you do this the before and after.

 

@boostedka what is your fuel pressure at idle looks like mine is 50-55 psi

 

Monday is a holiday, so most likely no deliveries.

 

I've been wanting to use that so maybe Tuesday

 

I don't have a pressure gauge so idk what I'm at

 

I'm running a Aisin 3rz disk, pilot bearing, and TO bearing with a 5vz pressure plate

 

header wrap retains heat. you want the aluminum skin wrap stuff for intakes

 

It really drives decent until I go above 60 MPH, then it wants to run lean. At a stop light, it will run lean for 5-10 seconds then richen up to stoich.

 

With meth injection, my intake is like 30 degrees cooler than any wrap could make it . I did seriously consider it though beforehand. My original idea was to put exhaust wrap and then slip over a bigger aluminum pipe over the wrap.

 

Well looks like my passenger side v band before the y is leaking a bit but i still thought it would spool some at 3k but ill see if i can address this one day. (please excuse the 30 seconds of me trying to get my phone to stand up) https://youtu.be/IviCcJgXG5E
I also realize that i wasnt holding it at 3k long enough to build any boost in this vid but i waa in my test drive vid; this was just to see if it was spinning freely

 

Can't you just tighten it?

 

Well i tightened it with an air impact so im gonna guess its misaligned

 

That fluctuation in idle rpm is bothersome. Are you still looking for a vacuum leak?

 

I dont think so; it was a cold start (my battery was dead) and i think its just cuz i dont have my tune fine tuned

 

What do guys think of a built w59 vs a r151f up against a ls1.

Like the ratios of the r151 but i have a w59 in my 3rz....have 4.30s with 33.3" tires and i feel like the high rpms it turns may not be best for fuel economy

 

Built w59 as in?

 

Like a 400hp clutch and see if a trans shop can build it to hold more power

 

W59 will likely hold that it's the transfer case that goes first

 

I've read on custom tacos a couple guys have ripped some gears out but all have said the t case should be good.

 

Kurt on CT broke 3rd gear on his W59 at roughly 350tq before he swapped to the 5vz 5spd tranny (I don't remember which R series that is)

The key to using that tranny is shortening the input shaft 1". He used a lathe to do so
