Probably run about 13.9 @ 98?

Just cut the cat off, no need for the magnaflow unit. And swap out the Flowmasters with another muffler and it'll probably pick up some. Other than that, hit up a catless DP, cutout and a tune.

Catless dp = Catless downpipe.

I'm pretty sure 13.9 bone stock is the record...but then again I could have missed something.

There was a guy named TonyGXP who with a headlight removed ran a 13.6 stock. This was in a GXP. I'll do some digging.

https://ls1tech.com/forums/ls4-perfo...-102-37-a.html


And I don't know how in the hell supercat ran a 106-107 mph with just rockers and a ported intake. (must have been downhill!)

https://ls1tech.com/forums/ls4-perfo...06-89-mph.html

https://ls1tech.com/forums/ls4-perfo...2s-almost.html 13.07's!

I think Travis needs to update the track times and place himself 2nd. LOL

13.26@105.17 2.05 60ft with a early 5980 shift. I now shift at 6500 and am installing headers so I'm hoping for a lot more. My dashhawh has recorded an improvement of .2 and 2mph more with the 6500 shift. I don't even know what to expect with headers. The cam was a custom grind from EPS and was spec'ed for use with headers. I plan on going back to the track in 2 weeks.

Here is my old tread with a few updates. The first couple of pages I went a little flip floppy.

Is there a place that makes the catless DP? Or are you guys just custom making them yourselves?
