Yea i prolly had 2000 miles of driving time on it set the way it was. I never really did get on it tho. I just screwed it in far enough to where when you reved the engine it would hang or the rpm would start to float so to speak, then id back it back out a turn. My tach recalled 4700rpm.
you have to cut larger valves to even get close to a 24v stock! stock for stock the 24v outflows a 12v 20%. iv had both on the flow bench and have one of each ported and polished, valve grind, intake off. i was even able to get 5% more flow out of a "schieds" port and polished 12v head ;-) the 12v is more desired due to it having less moving parts for use at higher rpm.
Did it run fine for a while then run away? I screwede mine as far in as it would go and it would settle at different rpm, quite high, but never run away! U must have screwed it in hard did u? What rpm did it reach?
wierd! Thats about where mine is set!!!!! Mine is just a 4 cylinder turbo diesel land rover TDI 2.5 litre. It has 130bhp ish and about 230lbft torque. Kind of feeble compared to this!!
thought u could avoid this by bein easy on the throttle let off??? cuz i turned my pump in this much and it did that on me(with no damage) but learned not to just let all off on the throttle.. guess i shold look into it more
Yikes, I feel real bad for that, or those, turbo's. With EGT's that high (and they would be real high with that amount of fuel), with it shutting down like that its going to cook them in no time. Nice looking truck though.
@kdiesel4255 I have to disagree in a sense. Dont want to be a jerk though. When your burning fuel, it does produce smoke. But, excessive smoke such as that is unburnt, for the most part, and is due to not enough timing, too much fuel, and not enough air. My truck smokes a decent amount, but as soon as the turbo lights, it clears up to a light haze. Dont get me wrong, i got nothing against some smoke on the dyno, maybe a ricer or two, but not everyday driving.
Thats a sick truck! What mods? Bigger injectors, VE pump turned up, aftermarket turbo(s)(ATS, industrial injection, Garrett, turbonetics, other) and stuff like that im guessing...
Missfire then clunk..... did turbo come apart and jam engine? I have a similar missfire at full power in high gear, can turbos cause missfire if boost is sporadic? I wouldnt have thought so but this missfire is annoying!
Head and rotor. I had the fuel screw a turn or two to farr, thats what caused the runaway. But the reason it shut down was because the 14mm head and rotor seized. The vane pump in the pump cant keep up with the amount of fuel that the 14mm h&r can flow. Even with massive fuel systems and fuel coolers its still possible to seize one up.
Just bought a '92 last week. Same paint scheme as this one. Since my income is limted (I'm a student) I'm going to mod my truck slowly over time....right now the plan is to first buy gauges, then do some pump work, larger injectors, and then I'll go from there. Any suggestions?
