If it can handle 65,000 the 2.62 would be pushing it, but it would work. That is good to know for future plans.

 

You're braver than me... I think the 2.62 will be too much spin. The unit may be rated up to 65K rpm, but that is for a no unit (no wear) under ideal conditions.

A little bit safer would be if you can figure out a way to mount the 50mm wide 34 tooth cogged gear in place of the stock 32-tooth one. Runs about 2000rpm less on the SC than switching the 2.87 for the 2.62.

Hope to have my 3.12" finally on this weekend.

 

I have the same kit for my ATI, just haven't installed it yet.

I was tempted to do the 2.62 on a stock motor, but I am not THAT curious to see what will happen. I am in no hurry to blow my motor, but another guy at the shop is considering low compression pistons and a 2.62 pulley upgrade in January. I will wait to see what happens to his car before I try anything like that on mine. I think he is trying to build a 200mph Z to run at the salt flats.

 

Still Dont think you will be able to get that 2.62 to turn with out scaping on the jackshaft and tearing it up like my 2.87 did to mine. Guess you will prove me wrong...lol

 

I think you just had bad luck with that pulley. I can't remember if you ever tried to get Vortech to exchange it for being a defective piece. It is worth a shot, especially since other people are running the 2.87 without any of the problems you experienced.

 

LouZer... I'll be tracking your progress. When I considered bottom end upgrades, I figured I would go ahead with the 2.62 AND a 34 tooth cogged pulley to get as much boost as possible out of the Vortech. Heck, I even considered sending the charger to Vortech for some of their upgrades.

Once the bottom end is done, it's all fair game for bigger boost!

 

In response to the guy who thinks that the car is making extra power by sucking of nitrous from the intercooler sprayer... you're crazy. The the time it would go through the compressor and back around through the intercooler it would be so dispersed and decompressed that it would have no measurable effect. Secondly I am sure there is a big fan in front of the car which would be blowing the nitrous all over the place..

If you've ever take off a nitrous nozzle and shot it in the air, you will see that it quickly disipates, and becomes normal air within a second or so. When you inject it in to a motor it is sucking it in, in a compressed state, which effectively emulates forced induction. There's no way for this to happen in the open atmosphere.

My car seems to have a mind of its own. Today it hit 11.5psi around 6400rpms. Previously it was at 10.5psi. I think that is the highest psi from a Vortech that I have seen. I don't know if I should be happy or worried.

I am going to hit the dyno again on Tuesday so we will see what happens. I am also doing a differential swap with a 5AT on Tuesday.

Longer gears + F/I = GOOD

 

Was it alot cooler today ? Cooler temps = more boost . I also noticed just I let off the gas from a WOT run....the boost spikes . Could be some reasons for the extra psi

 

hmmm. It is cooler. It was raining on and off today. I know that it wasn't a boost spike because I had a passenger watching the boost gauge.

 

I know the night I broke the piston...it was alot cooler and I was seeing over 9.5lb's of boost . Normally it was just over 9lb's

 

I guess I will just take it easy during the winter. Well... I will TRY to take it easy.

I don't want my next thread to be: "I just blew up my engine!"

 

Well I dont think you will see the temp drop as much as we do here .Its already getting below freezing here at night

 

And I thought your other avatar's were patriotic. I'll salute that anyday.

And yes, in the Bay Area temps don't get anywhere near freezing.

 

Election is over...all is well....I can go back to the funny avatars...this one was taken off by a Moderator for some reason .I was never told .Some one must have complained about the bounce ...lol By the way....I love the Bay area and any where north of there

 

I just did a differential swap with an AT 350Z. OMFG! First and second gear are awesome. First gear especially. I can now do 0-60 without shifting into third.

I highly suggest doing this swap if it becomes available. Luckily I had someone who wanted shorter gears in their AT.

 

Sounds cool Lou Are there any other noticeable differences throughout the other gears? Top end experience, more precisely?

 

From what I could tell I gained an additional 10mph +/- in each gear. Of course this is not exact. I can also stay in a lower gear longer without shifting. This is great when up shifting. The only downfall is that you have to downshift more in city driving to keep the rpms up. Second gear is great because you can cruise around at 15mph, but also use it at 60mph.

I would only suggest this for F/I owners because N/A cars (MT) do not have enough power for this to be a benefit. The swap is only a benefit to N/A (AT) cars because they get shorter gears and can rev up faster.

 

Are you retarded. The N20 intercooler sprayer is like a round tube that is cooled by the nitrious, then the bar cools the intercooler. No nitrous enters the intercooler or the piping. How can it reach the filter if it has already gone through the intercooler. The filter is before the intercooler not after it.
