Running a bone stock Z6 on 15psi (t25). This is just my high boost setting...

Anyway, i've contemplated running a small dry shot on top if it. I can only find 55hp jets. I think that will be overkill.

Anyone running a smaller dry shot?

Thanks

 

damn yo thats pushing it man. I wouldnt feel safe making over 240whp reliably just because of the rods there not very stout and can break pretty easy. I would hold off on that nitrous shot.

 

Hold off on the nitrous. I say upgrade to a bigger turbo/build the engine.

 

It's more less for cooling or the intake temp purposes only, hence a tiny shot. If i could get a 30-35 shot jet or something. Not looking to gain huge HP numbers, just looking to get a quick burst of cooling efficiency

I'm sure the tuning will take care of the rod dangers.

 

what headgasket? studs? head lifting chance?

then just get a alki injection kit..

 

Aftermarket head gasket. Nothing special...copper sprayed, bla bla.

ARP Head studs. All installed say....25k ago?

I would most likely do a compression test before i did anything on top of the boost.

As for the nitrous&gt;Alcohol, my buddy has the nitrous bottle/solenoids/lines lyin around in his garage collecting dust.

We were originally going to fab up an intercooler sprayer, but figured why waste an assload of nitrous to spray the intercooler and gain maybe 5whp, or just spray a (motorcycle nitrous kit jet perhaps?!) 35 shot (if it exists...) and gain the efficiency of the cooling and a bit of HP.

This is all just an idea we were floating around since we had the parts. Might just end up rigging the sprayer, but i wanna be sure bout the jets first.

Thanks for the replies so far

 

What nitrous kit?

I used this site to calculate the jet size:

Then ordered the jet from summitracing or similiar some time ago.

But you probably have a zex kit and I think the smallest size that zex had was for a 55 shot?

 

^Great link

 

this "cooling" you want is retarded, I'm sorry, instead of spending 400 bucks for a nitrous kit and 50 dollars to fill it why not just go buy a water injection kit for 300 and costs ~1 dollar to fill and run higher boost? Not to mention you want to run a dry shot which doesn't add the fuel along with the nitrous. I'm sure you'd enjoy having 2 separate fuel maps for them...

And by cooling the intake charge (what you said you wanted to do) is only there to increase power and decrease the likely hood of detonation, all of which can be gained/countered with water injection...

 

The point of this was that i already had the nitrous parts laying around.
Only cost: Empty bottle


I understand water/meth would be the ideal setup here. I'd rather buy the Zex cam than that right now.

I just had the parts, and wanted to make a few more hp without cranking more boost.

No harm done. Just wanted to know what my options were.

 

i wasnt trying to be mean i was merely just laying it all out, a dry kit plus boost is a bad idea if you dont have it tuned extremely well, even a wet kit is pushing it considering with boost and nitrous everything changes

 

Fair enough.
When it comes to making D-series power.....you're the guy to ask lol.

Maybe we can just fab up that intercooler sprayer for next to nothing and just try and gain a handful of HP off that.......and possibly spring for the Zex cam and make pow4!

 

in all honesty i wouldn't use it as a intercooler sprayer that is just a waste IMO. I would use the nitrous since you already have it to make your own jet and maybe run a 10 shot or something similar.

What engine management are you using? Because once you add nitrous to a boosted application or any application for that matter you really should have a secondary map just for that

::EDIT:: and yes get the zex cam it is WELL worth it, on my setup it made 39hp more than the stock cam and 32ft-lbs more its night and day difference

 

I dont have the tuning accessability in this area....i.e.- no reputable tuner.

Also, my ECU is chipped with Uberdata which noone seems to want to tune anymore. If a seperate map is required......def. not worth it.

ZEX cam is QUITE tempting........so is running the stock valvetrain.....which is what i can afford.......but NOT what i want to do

 

i ran the zex cam on my stock valvetrain without any issues i just didnt rev it higher than redline until i got springs/retainers

 

just boost it stock...... i ran a stock z6 for a year on 15lbs.... Ran 12.1 @ that lol
good luck
