Hey guys sorry I was busy. Where I got my work done they have done a lower and upper pully and their was no gains over just doing the lower because the blower is pretty much maxed out. It's a very small blower. To answer your questions I went 10.7 at the track my car was cutting out when I was shifting I think it was because I didn't transfer the sensors from the stock tires to the replica 19" rims and nto5r tires. I'm putting a F1a-94 procharger with the install it's $10,100 and I'm doing a McLeod clutch and meth kith everything is $15000
So the shop said there is nothing to be gained by doing a pulley swap??

Lol. Sometimes things have to be repeated exactly twice to be believed!!

Your sentence structure is one that does not convey what you're trying to get across. I have done an upper and lower and yes there are gains to be had. 2.3/9% is the perfect pulley combo on a cam car.

Seems like once you go 2.3/18% combo, you have to do serious porting/cooling mods and a cam to use it... A buddy of mine just tried it on a ported blower, stock cam deal and the engine choked up big time..Only gained another 20hp but nosed over up top..made a ton of PSI but not a lot power.. Needless to say, its down for heads/cam now. I think you can only shove so much in with a 189* intake lobe.

The 2.3/9% combo (24,570) is basically the same as the 18% lower (24,700)....Definitely good for 730-740 rwhp on E85/Meth with a cam.

1-2psi or if that is still bad for it with a 18% lower

I said the blower is maxed out with the 18% lower so their is no HP gains by doing the upper pully as well what is so confusing about that. You just creat more heat which is pretty much the same this that ajrothm just explained. There is nothing wrong with my sentence structure.

I've personally installed the Innovators West 9% lower. Very nice piece. NOT easy to install, but is straight forward. Need to remove front wheels, steering rack, lift engine a little, etc.
Since I have a lift it was reasonable...3-4 hours.
Advantage of lower is that you get a better harmonic balancer also. The damper is fully engraved for setting timing accurately and any race engine would like want to have it.
Even at 9%, butt-dyno feel the difference. Car pulls hard all the way. Nice mod!

Looks to me a upper is all I need, after that instead of spending all the extra money on cooling mods easily 3k with meth I will just go with a Maggie for around 4.5k.

Well, this is kind of an old three, but I was searching over here to see if I could find what the max rated rpm is on the little 1.7 blower we have... but I digress.
I have my 2017 ZL1 at AMP right now being tuned and thought I would chime in on what we have found so far since it is the same engine (by and large). Here is my build thread over on Camaro6, but long story short my wife and I pulled the engine out of my 2 month old ZL1 and did intake, mamo tb, Texas Speed LT4 heads, VVT1 cam, ARH 2" headers, long system, 15% lower, And DSX e85 kit and low side fuel system all in my garage.

So, how does this pertain to this thread... Well, what we have found so far is that on an e85 mix only (notice no meth, and I will have to ask what percentage e85) it is currently making about 740whp through the a10, and at only 12lbs with the 15% (9.20") pulley. We are having a Lingenfelter 18% (9.55") overnighted as with the low side fuel system we still have room on the fuel side. So far both low and high pressure is remaining steady.
From what I have seen, if you really get to the point where you are looking for power, without creating a lot of heat and excess boost, you will have to look at doing the heads, adding a cam, and supplying more fuel. So far the iat's are well in check even spinning the 1.7, but a lot of that has to do with increasing the ve. The TS VVT1 cam is a relatively mild cam as I wanted something that would play nice with the a10, so I am fully convinced that a lot of the gains are from the heads. When I received the heads back I did notice that much of the porting was done to the exhaust side, which on the LT1/LT4 heads is the primary restriction.
Anyway, this thread kind of centers around pulley options, boost and heat. I have read where many have basically said "if you want more power just put a Procharger on it and crank up the boost" and while this is one way to do it, I would argue that it is not the "right way" to do it. When all is said and done I will be looking at a car that makes a solid 675whp on 93 and 740+whp on e85 and no need for another potential point of failure i.e. meth. KISS principal...

Great write up and eventually i think I'm going to go the same route. saving your build tread. I to like to get out on the road and don't want to be stuck. i built my c5 H/C/I in my garage is this about the same difficulty level? I'm not far from you. my GF actually lives in prosper.

Here's some "real life" input from what I've actually done...
I bought Joe's Pulley, but did not have a press in my little personal shop, so decided to shift gears for now, and since I do have a full two post lift, we went ahead and put on Redline's 15% overdrive pulley.
I still may do something with Joe's 2.3 pulley down the road, maybe just for 1/2 and standing mile stuff...
I do have one of Joe's Custom pulleys on my supercharged C5, and the machined in "grit" he uses on the groves works pretty well!
As far as what else I did with my C7, I added the Halltech Intake, Ported TB, Meth and Billy Boat Exhaust, including X pipe.
To help with Cooling, I also added the Granitelli Expansion tank and an extra Radiator with spal fans for that extra fluid in the expansion tank.
I then went ahead and tuned the car on 91/Torco with Meth. We came out with 660/690.
Let me simply say that I'm SUPER happy with the outcome and power levels!! For what I do, it's a GREAT combo. I like to hit the canyons, road course once in while, and then go to the runway twice a year. I've already been to the runway, and done many canyon runs with this combo, and will be hitting willow Springs this Saturday. I've been on the road course twice, just not with the pulley yet, NO HEAT ISSUES. Since I added the Pulley, I will be running Meth as well of course, to aid in cooling...
For me, these power levels combined with the handling/braking the Z07 package offers, and Toyos I put on the car, make this Z a blast to drive. If you are looking to break records at the 1/4 o 1/2 mile, or are just concerned with BIG dyno #s, then add more boost, and have at it.
Again, my real world input, is that this 17 Z is an AWESOME looking and driving car, that just needed a few tasteful and light mods to get to where I needed it to be in order to have a ball with it!

I just would be interested about your auxilliary radiator install, as I also intend to drive over muntains and like to get that IAT temps lower. do you hve some pictures of your install and parts or manufacturer numbers
thanks
