Bad night.. Lots of oil and lots of smoke (carnage pics)

I thought he was running Headers.
Wouldn't they eliminate the restriction on #3 exhaust port.?

Thank you, Aaron. I can't believe simple water hurts the damned coating!

It's not so much the composition of H2O, it's the velocity of the droplets as they hit the spinning rotors. If you've ever seen a water jet cutter at work, you can understand how this might happen.

Headers help, but the front bank still has a longer route, and that cylinder location still gets hotter.

Water injection has been tried but it has been shown to eat away the epoxy coating on the rotors, lowering boost efficiency.

#3 is in between #1 and #5, making it hotter. #3 is also on the front bank, which on a stock engine has a more restrictive exhaust route. These factors make #3 more prone to detonation and piston failure. #4 (on the rear bank) is also at risk. It is for this reason DHP tunes the PCM program so #3 & #4 cylinders to receive a slightly higher amount of fuel compared to the other cylinders.

Genny V's are a whole new animal! They have a different rotor coating

The coating might be better for efficiency and lower friction, but how do we know "different" means it will stand up to water injection? Besides, wheren't you talking about N2O anyhow?

Yup i will be spraying a Wet shot through my GEN V.. I have heard.. and read that the GEN V rotors hold up to nitrous,gas,water,meth going through them.. I am hopping on that bandwagon and agreeing with all who i have heard this from!! My rotors are perfect..

Don't believe the hype, man. Although you might be able to get away with N2O, as it's more of a gas than a mist when you spray. I don't think that would hurt any rotors, Gen III or Gen V.

Btw, a "wet shot" would mean you are mixing fuel with liquid N2O and injecting after the blower (LIM). If you are spraying N2O directly into the intake, that's a "dry shot".

And for the record, I'm not a fan of the 9.4:1 compression + boost!

Actually I will be using a "pirahna nozzle" It has ONE nitrous jet and one GAS(e85 ) jet... It will be placed in my TB spacer/adapter.. looks like this

Do they all it a Piranha because it chews up Teflon rotors?!!

Done right, you should run 12s with N2O. Tune carefully, and good luck!

Photo tip: press the little "flower" button on the camera next time you take pics of a spark plug!

LOL it won't be for a while man!! I hope to run very low 12's on the giggle gas

I was using a Sidekick LX.. lol not the best picture.. I know

I just read this whole thread and when you said L26, I immediately thought of this: http://us.geocities.com/shawn_kato/l26.html

nope! that motor would be the last motor i ever swapped.. lol

Wow that engine sucks, it runs out of steam at 4100 rpm! No wonder GM went to the shitter.

It's not quite as bad as it looks for itsself. It gets a heavy body caddy from stop to cruise pretty quick. What I think is funny is that motor is an aluminum block with iron heads lol

Been extremely sick the past 2 days.. haven't gotten a thing done.. H1N1 FTMFL

Been sippin' too much E85, Travis?

Yes

So, any update Travis?

First day back to working at it was today actually! I got the new 3.8 all ripped apart and got my old heads which were worked on put on the new block.. Stopped there for the day though because i need some RTV and some other junk Should be done by Wed night if all goes well

Got it all put together. just have to clean out the engine bay.. clean the grease off the wiring harness.. than plug the wiring harness in and drop the motor in! like 3 hours left.. and some wiring of some gauges!!

So, what all do you have planned for this engine? Maybe a bulleted list would help me out. It's hard to follow everything that has happened in this thread.

-L26 bottom block 9.4:1 compression 15k miles on it
-L67 heads worked, valve job and decked and re surfaced
-Gen V ported with a ported matching LIM
-3.5 pulley for the winter (12 lbs of boost)
-93 octane for the winter, E85 again next spring
-Headers
-1.9RR's

I rebuilt it with all new gaskets and stuff..don't know what else you wanna know?

Buying a wideband
