I'm in a debate with someone right now and I'm wondering what the dyno record is for a N/A LSx? Any c.i. just as long as it's N/A.

Thanks,

Stephen

I think Six speed Inc made 715rwhp N/A With Solid Roller 15:1 Compresstion 403Ci ET 255 heads.

Pump gas I think the highest is LMR 628rwhp built for a customer 11:8 Compresstion
454ci LSX TFS 235/FAST 90/90 Setup through M6 N/A.

LG has a c6z that did 632..

FWIW, the motor that the 6 Speed Inc has in it now is MUCH stouter than the one above.

Also there are many more that have just never been on a chassis dyno..

I know of a square port mill that made 1028 on a soft brake and 1002 on a tight brake. 448" LSX w/ -R heads.

A rumor has it that some crazy guy in Buford GA has made over 1100.... No confirmation on that though.

I am sure of one thing....some real nasty lsx stuff is around that we don't know about.

Exactly. People see, to forget that while this is the biggest LS board, it does not include everything that happens....

Good job.....

kind of hard to compare #s when every dyno brand gives u a diff reading let alone dyno to dyno.....
