TRD supercharger

Still interested in your axles

 

They will be available. Working out some details as to which front kit to run. Either throw a 4" Camburg spindle at what I have or swap to their race kit, just comes down to hubs

 

Then why does Toyota state that it should provide 5-6 lbs of boost?

 

Apparently some people read higher boost with alot of stock stuff. Not sure if its because of to much back pressure or clogged cats or something, but normal boost readings are 5.5-6.5 with just the SC and then boost increases a little with each bolt on, and the pulley should get your up around 7.5ish.

 

True Story.

Except I'm still getting 7.5 with URD Y Pipe and 3" exhaust . Headers getting installed with LT though! So that's a win, then It might actually be time for a dyno run! and then another post regear dyno run

 

That is really frustrating because with a pulley I could potentially be pushing 10 and from what I've read that's about the limit for stock internals. I should see if there is someone local who has a calibrated boost gauge that can verify that.

Stupid VA emissions standards...

 

Ok, again, as stated above, just because you are seeing 10, doesn't mean you are seeing the HP that could cause internal issues. As we've said before, the standard boost levels are about 5-6 or so, with a pulley you should be right around 7-8 or so. But I would HIGHLY recommend you upgrade your intake and exhaust before you go upgrading your boost levels.
What kind of gauge do you have and is it installed correctly as well?

 

Please. Just...please. I live in California, I don't wanna hear about emissions crap from anyone, I run what I run with every intention of swapping back to stock for my smog tests

 

I'm running a Glowshift boost gauge which I know isn't the best but it is installed correctly. The intake has been upgraded but I guess I should look into a new Y-pipe again.

Random thought. Could the FPR mod be messing with my boost readings? I'm going to go check that tonight.

They put these stupid emission sniffing vans all over the place and send you inspection notices if you are even slightly off. At least you don't have the risk of jail time for a simple speeding ticket! (AFAIK)

 

S/C was new and installed on the truck that I am the only owner of at 2.5 years and ~25k miles

Mods all installed after the S/C: AFE Stage 2 Si, Dynomax catback, Boost, Oil Pressure, Oil Temp, Wideband AFR gauge, FPR Mod

 

14.7/14.8 at idle and right around there when doing 50 mph. I don't have any issues with gas mileage and the truck has plenty of power so clogged cats shouldn't be an issue, right?

Probably spent a little too much time over on XRU and figured it wouldn't hurt to do the FPR mod with the vacuum line I had laying around. I'm running a 320 LPH fuel pump.

 

Boost gauge is reading ~8 PSI at WOT. 21 vacuum at idle, I can double check what it is at 50 mph in the morning. I also have a wideband that reads below 10 at WOT and around 14.7 at idle and cruise.

Hope that solves the confusion haha

 

Yeah but fuel richness shouldnt effect boost pressures. I'maiming towards cats or messed up boost gauge

 

Well that certainly makes me feel better. I'm going to try and get my hands on another boost gauge and see what it reads before installing the pulley but it sounds like I may be one of those anomalies (or the Glowshift quality that they are known for is shining through)

Thanks for all of your help @memario1214 and @VolcomTacoma! Will report back with any findings and if/when I get that pulley installed.
