CRX B16a Supercharged at 11lbs.
Motor blew at a Solo 2 event

mmmmmmmmm.........

What motor next ? ? ? ........................



.

 

wow...thats not pretty

 

You need to address those lean conditons on any motor you go with . I would go with a 1.8L at least , build the bottom end and stay around 10-1 compresion.
You will need to bring those intake temps down , or lower the boost and run a little less timming.
What kind of management are you running ?

 

I personally don't think the motor blew up because of a lean condition but timing or detonation could have been what killed that poor thing.

I would just get a gsr block with compression somewhere in the mid to upper 9's and rebuild that head if I had to choose a new powerplant...

Adi

 

Most of the time detonation is caused by bean lean , and too much timming.

 

Looks like it was a little warm in there.

 

so are those holy pistons now?

 

hehe that's my buddys car , we pulled it apart this morning to find that lovely mess

 

I haven't seen anything that ugly since sprayed an open bottle on a JRSC d16!

 

time for the jbweld

 

trashed ouch good luck with the new build

 

what was your fuel setup?

 

what he said..

what is your setup... JRSC?

better have another

 

I dont think that had anything to do with fuel management or temps. It looks like a dropped vavle or a overrevved engine floating the valve. All the damage is form collision. Auto cross events tend to have many high revving shifts so my money says it was downshifted a tad too early. Sorry bout the motor but now oyu have an excuse to spend more money WEEEE!

 

i dont know what you guys are talkin about...

its still good

 

Fullthrottle was right. everyone thought it was a leaned out condition but thats a dropped valve. no doubt. overrrrrrrrev!!

 

No doubt that valve dropped.

Looks like piston number one has some melting or something.

Not sure why it'd be white unless something got lean.

 

I broke everything on run #2
but I do admit in run #1 i did over rev the motor but after
I went a drive on the strrets for a bout 2 min not high revs.
Run #2 I gave it out of the hole after 2 turns a straight aaaaaand bang
Destroyed

Can run#1 drop and valve but yet continue to let me drive to run #2

there was 1 hour waiting period from run 1 to run 2

also that valve thats busted the valve retainer is broken in half.

any help is appreciated

thanx

 

If you overrevved it the piston may have made slight contact with the valve cracking the retainer or knocking a keeper out. Then on the next run all hell broke loose (pardon the pun).

 

god damn bro good detonation just a lil too much lean I guess that throws the statement that superchargers are safe out the window

It was OVER-REVVED.

Anyway, bummer. I'm guessing that with 11psi non-intercooled and B16 type static compression something was bound to happen anyway.

I bet it's nice autocrossing with a SC. I autocross with a small ball bearing turbo on my LS swapped hatch. It's a little hard to contol coming out of the corners when the boost comes on. It's not like my car needs any more reason to understeer.

 

Question ???

GSR - ALL MOTOR
OR
B20Vtec - All MOTOR

any suggestions

Obviosly GSR will be cheaper

 

any suggestions to above
