Stock Bottom Ls1 si trim and ysi rwhp record?
Does anyone know the stock bottom Ls1 Si trim and Ysi record. I know of 2 C5's with ysi making in the 900 rwhp range but both are ls6 I think.
I have an Ls1 ported 317 Heads, cam, headers, twin fuel pumps intank. Currently in the shop doing 10 rib with Secondary drive, mantic twin disc, and alky meth going to be overdriven balancer and 3.33 blower pulley on si trim. I have all the parts in place to do a ysi and injectors and see what it makes. I might be able to give both the stock bottom records a run but I don't know what they are. I have no plans on quarter mile records lol. Its a 6 speed car and don't run at the track mostly street driven and roll races.
btw I have an iron block and rotating assembly I am looking to build a shortblock next year sometime. So I am a step ahead if it goes kaboom
Thanks,
Rob

Can't wait to see what happens. You're in a good spot though since you have that block and rotating assembly ready to go.

I know they are but was wondering what anyone made with what started as an Ls1. Also, I think my block is technically different weren't there changes to the blocks in 2001 when the Z06 came out? My car is a 2000.
I can't wait either ready to get this thing done and ready to cruise.

I was wondering what my pulley combo would make with a ysi instead of an si. That would be sweet. Didn't you end up making like 920 ish on you ysi stock bottom end car?

Thats serious!!! Your car and Milan are the highest I know of on ysi stock block. I am surprised he didn't reply to the thread. Is anyone pushing it any harder than that? 900 rwhp seems crazy on stock block!!!
No room for error on that tune
