I blew my engine on 98oct Ron and 1,2bar boost, 2 pistons melted down and the head has an opening between 5and 6 cyl.

standard steel plate, say 2mm

i had about 58mm 1,2-1,25bar

the cylinders have some scratches but after a ,020 bore it will be fine. This volvo im talking about is a 16v engine has ran 7,62 288kmh 1/4mile. He had the engine mapped today with Ethanol, the think broke the freakin dyno

the price is one good reason, a friend of my is an expert on welding heads, he is a dragracing ceneberty here in scandenavia and runs 1200hp+ in a 4cyl volvo engine, the man knows his shiet

yep.. oits as nasty as it gets, total engine rebuild and i have to get the head welded and skimmed.

Lyfte av toppen idag och kunde konstatera att det var ett ras modell BIGSIZE! Bilderna säger nog en del.. ps: topplockspackningen är 3lagers stål. ds. http://medlem.spray.se/arminracerx/Supra/3.%20Ras+Godis/KODAK%20025%20(Small).jpg http://medlem.spray.se/arminracerx/Supra/3.%20Ras+Godis/KODAK%20027%20(Small).jpg http://medlem.spray.se/arminracerx/Supra/3.%20Ras+Godis/KODAK%20030%20(Small).jpg http://medlem.spray.se/arminracerx/Supra/3.%20Ras+Godis/KODAK%20031%20(Small).jpg http://medlem.spray.se/arminracerx/Supra/3.%20Ras+Godis/KODAK%20028%20(Small).jpg I got some problems, it was worst than i thought.

sounds nice, i hope that i haven´t got more damage than that.

this sucks.. my engine is dead, i got no compression on the 5 and 6 cylinder.. the car lost 2 cyl on the freeway after passing another car with some boost.. it runs fine on 4 and no smoke or anything, i had maybe 1,2bar with these mods.. decats, rr and 3" exhaust bcc, walbro gss341, bcpr7es plugs. what do you think is broken ? pistons. head valves? Btw: i had two fried plugs aswell on the fift and no 6 cyl.

read again..

This thing happend to me today.. my supra is broken my boost was 1,2bar and the RR was a bit over 2", greddy bcc, dp 3" exhaust and a walbro gss341, plugs were ngkbcpr7es.. the plugs on no 5 and 6 cyl had their top burned off.. and now ha have none compression on those two cylinders. This sucks! any ideas? melted down pistons? burnt valves? The car runs fine on 4cyp and no wierd smoke or anything comes out of the exhaust pipes..

thanks for the tips guys. the goal is a 12sec run on the quarter, three weeks left to the event.

Problem solved... It was a earth cable that wasen´t attached, the car runs perfect now, but too much boost, 20psi+ Need to install the RR, is it okay with a 60mm hole? the cable must have something to do with the coilpacks or injection.

will do that! but the MIL light hasent lit yet.. i thought the error codes made the light go on.

I have a brand new exhaust system, its 3" free flowing all the way.
