I need some assistance out there. I have a friend who previously built an LS/vtec bored to 2.1 with 13.5 comp pistons, flat faced valves, s2 pro 2 cams, extreme port an polish, and of course rods, bolts, v springs, etc.... He had a shitty tune done on the car the day the motor was started. The car came from the dyno smelling like gas, and his valves punched there way through the pistons that night. (All this occurred before I knew this guy)
Now I am trying to prevent this from happening a second time, but he just will not listen. He has currently built the same setup except this time running 14.1 comp pistons along with flat valves. He thinks he can run this bomb on pump gas with the same tune from the previous detonation. I appreciate all input on the matter....

 

You are pushing it with that comp ratio. Not only that but he needs to check clearences first as well between the valves and pistons that also could be an issue.

 

let him rebreak that crap... and quit hondas

 

aight I know the guy too.. this is the full set up from BEFORE AND NOW

BEFORE:

B18B1 Block
B16 Head
Type R Tranny
Darton Sleeves
ARP Head bolts
85mm 13.2:1 Weisco Pistons
Eagle Rods
Eagle Crank
Extreme Port and Polish
Port Match on the Headers, Throttle body, and intake manifold to the ports on the head
70MM throttle body
Skunk 2 Pro Series Intake Manifold
DC 4:2:1 Headers
Skunk 2 Pro 2 cams
AEM cam gears
Type R oil cooler
Greddy timing belt
Unorthodox Lightweight pulleys
Skunk 2 Valve springs
Skunk 2 Retainers
Ferrea Intake and Exhaust 1mm oversized valves
7 Angle valve job
MSD ignition
Ebay 2.5 catback exhaust
Hi Flow Cat
Running 93 Octane Gas
Hondata
CRAPPY TUNE - car came back running super rich, STANK like gas and cams sounding like a v8.. you know the sound.

This set up made 199.8 WHP and 149 150 ish ft/lb torque

Engine blew with in 6 hours of getting it back, he broke a valve guild, broke a valve, and the valve punched holes in the piston top and then scattered tiny pieces metal throughout the whole head and put scratches in his cylinder walls.

That is not a shitty tune, that is called mechanical interference.
The best tune in the world will not prevent engine damage when the pistons kiss the valves.

 

can you say BOOM!

93 octane lol

 

P2V!!!!!

 

He only made a 199 whp with the old setup?? That sucks. His motor will go to **** again if he tries to run 14:1 on 93 octane. Just let him learn again. 260 whp not gonna happen.

 

199 is da bommmm!

 

It's nice to have money!!

how does he have ITB's, no port match on the throttle body, AND ITB's?

either you just threw together a 17 year old honda fan boy christmas list or you dont know what you're talking about

opps my bad, i just copied and pasted from the "before" time, my bad, no throttle body.

 

pro 2 cams with flat faced valves and over 14 CR will denotate instantly on 93 octane...i hope he uses race gas if he plans on having it as a DD!

if he wont listen then just let him do it, when it blows up just tell him, "I told u that siht was gonna blow" or "shouldve listened to me" or u can always just laugh in his face! if they wont listen then just wait till it blows, wat else can u do? he probably thinks that u dont know as much as he does!

 

his loss not yours so let him be...you live and you learn

That's exactly what it is. He might know more than I do on somethings, but this **** is common sense...

 

93 octane and 14.1:1 comp,,,yeah right,,,,, if that is the case just run 91 with 40.75+ of timing at 6000-9000 and get back to me on how that works

 

punch him in the mouth. better yet. tell him that if he blows it up he has to give it too you so aleas then it will be in better hands

 

His money his car. His KaBoom.

 

Considering that I'm having detonation problems at low throttle with 11.3:1 and 94 octane, I'd love to see how that motor functions on pump gas

 

i guess having lots of money makes up for having no common sense?

 

Ya damn right....I'm actually going to bet him $200 that the motor doesn't make out of the break in period. He said he's going to drive the car for a 1000 miles for the break in period....not going to happen
