i know my SI is hot to the touch when i get home from a drive. Never really had the SC blower working, before the bearings went so i dont have much of a comparison.

I know its definetely working harder bc we are seeing boost levels at 5-5.5k rpms that SC owners are seeing at redline.

Oil cooler is on the short list of immediate mods. My meth kit i'm sure helps alot with AIT (and like was mentioned wouldnt be seem by the UTEC since the AIT probe is before my spray nozzle) , but it doesnt cool the oil that feeds the blower.

Jet, is Sam still tuning yours?

 

i will keep you posted. Sam should be making more pulls tonight after he installs my new belt. he mentioned he has to do the pulls after hours due to my exhaust being so loud. the techs in the shop would not deal with the noise. they are fabricating a "H" pipe into my exhaust to try and get the tone a little more melo and possibly add a little more tourqe.

 

hehe dude your exhaust has to be bonkers loud
test pipes on a NA Z is loud as hell
supercharged would be like especially if you reduced the big *** rear muffler

The H-pipe will probably bring a lot of the barking roar back into the sound. My APS exhaust sounded like *** before my X-pipe

yeah IMO you definitely want an H or X pipe - just something to connect the two sides. It'll end up being beneficial for the vortech

 

^So did his

 

When I had test pipes on my Z sounded like a fricken F1 car at wot. Sounded awsome way up high but otherwise was way too much.

 

you should hear mine, open cut out

thanks, hope it works out for you.

 

Your NX kit....is it a intercooler sprayer? If so whats the review on it?

 

If this does not work out i am going to throw in the towel and start my engine build and go TT'S for sure!!!!!!

 

I think jksstar actually runs a nitrous shot on top of the vortech right?

 

^NoOOOOO, Don't leave me brother!

 

Its not a intercooler sprayer. I run a small shot with the Vortech

 

I think you'll get it working
you might want to get water/meth injection sooner rather than later though.

I am kinda starting to wonder if the REVUP maybe isn't as ideal with the belt layout as a modified non-REVUP's though when pushed to the absolute extreme. If you can get it to not slip, you should be good.

 

if it works out, water/meth will be the next mod for sure. Sam is going to think about adding another pulley, where? i do not know. OFF TOPIC ALERT. on a lighter note, here are some pic's Stan took the other day out a red rock before i sent my car to Sam.

 

I had very little slip with mine Sunday (up to 6500rpms) I just can't recall how much boost it was making (think it was around 15-16psi)

 

That white one looks slow.

 

car looks great! the way you pull off the yellow/black combo works really well in all the pics I've seen of your car.


Yeah I don't know where you can add a pulley on the REVUP from what I've seen near the jackshaft. That horizontal top stretch of belt doesn't have enough room for another pulley I don't think, but maybe it might somehow, or maybe the lower pulley can be moved lower and made smaller to make room for an upper small pulley to be added?

that last long vertical stretch and only getting 50% wrap on the crank pulley are the two other problem areas with the REVUP


maybe you could do a "TIMROD" setup to it like this?

 

so why no dyno #'s? sounds like it ran full bore.

 

Thank you for the comment! and yes that could be a possibility on the belt routing. Sam was thinking of adding a small pulley between the s/c'er serp pulley and the idler to the left of it so there would be more contact on the serp pulley and less chance of it jumping off. space is limited so it might not be possible.

 

As others have said.....Sam seems to only tune late at night after hours . I dont think its because his Mech.'s dont like the noise . Loud exhaust's comes with working at a performance shop and to expected .

You guys are starting to run into your belt problems all of us do , including the ATI Procharger guys run into . And thats trying to turn a blower that gets harder and harder to turn as boost rises . and trying to turn that blower with a flat serp belt . Its only going to be able to grab that pulley for so long . When the boost gets to a certain point the blower is just to hard to turn and the belt slips . No matter what you do , as long as it is a serp belt , it will slip or try to jump off the pulleys . Even an all cog pulley system runs into belt problems when boost gets high .

 

yeah just getting into the sweet spot of a setup with a combination of mods is the trick. Once there, it's smooth sailing
