The 10.802 @ 126.84 is my PB. That was on a trip to Sacramento Raceway in Jan 2015. The DA was -506'. The track prep was not great, since the 60' on that pass was only 1.54. Here in Phoenix a few weeks later with good prep, my 60' was in the 1.48 - 1.50 range. The ET's were in the 10.90's and MPH's in the mid 125's when the DA was 1200'+.
I haven't been to the track much after that, due to the way management decided to only run open track once a month and combined it with time trials for big events taking place the following day. When they charge $40 and the crowd is so big you only get one pass in 5 hours, the fun is gone. My racing buddy crashed his car over a year ago and I haven't run since then. Maybe I'll play some next Winter. The DA here will never go negative, so I don't expect much. I've even slowed down everyday driving. I turned 150K miles last Sept and not yet at 153K.
I hope you keep going forward with your mods. You already got a great start, so I'm wishing you the best.

Obviously, you don't understand the rules here and apparently lazerlemonta does, since he posted his timeslips for inclusion into the forum performance list under the category for LS3 internal modifications. See https://www.corvetteforum.com/forums...post1597056055
You never said stepped headers, as in size changes for adjoining pipes, or that the size changes weren't limited to just those two. So yeah, you were wrong.
You can either tell the whole truth or it's meaningless. You sound like a liberal snowflake that can't handle reality.
See what I mean about checking stuff before posting.

Either way lazer actually calls his car a bolt on car but because you guys throwing a hissy fit over something worth 8hp he’s pretty much given up on it. But I do have to admit it’s pretty hilarious you posting the rules like they’re something god himself wrote and are not open for discussion. I’ll bet you were the kid in class who reminded the teacher about homework.
I’m still waiting for that answer though....since he crushed your record by many mph and tenths do you think he gained it all from a bolt on mod like rockers? I mean if he did why doesn’t everyone just skip a cam swap and go for those?
If anyone here sounds like the snowflake stomping their feet about trivial things like that it’s you 😂

Sounds like someone is sore he couldn't go that fast with stock heads and stock cam. Heck many people can't go that fast with heads and cam in here. Can't wait for you to run your Z

I likely have the only set of the new hooker tri y headers that are 2"x2 1/4"x 2 1/2" x 3" on a stock head stock cam LS3. I posted a review thread and got zero comments. The headers are worth a solid 10 RWHP from 6200 up. Really I wasnt far off of the record bolt on time with no headers lol these rockers are wicked being worth a whole 8hp
Ps. Dennis made more power with the smaller headers because he had stock LS2 heads. If he had an LS3 he would have made more on thethe 1 7/8".

Your review thread of the hooker headers. Did you have dyno results as well?

Just remember that you're (your) giving up about 80 hp and 60 tark by using those inferior 1.75" headers. You kneed 3.5" connector pipes too (to). Wish I'd known this before reading it here recently. Dammit.......Guess I'm doomed to ride in the slow lane

This just for REDBIRD who has zero, zip, nata, nothing in his profile since he joined 9 years ago. He's apparently too embarrassed to list his 1/4 mi. times, maybe because he really doesn't own a Vette or mom won't let him race it. Oh wait, it must be those pesky rules again.
I'd like to hear his reasoning why this guy shouldn't be running those small 1 7/8" primaries at his power level.

Anyway yea totally valid comparison....just because a drag car uses 1-7/8 makes them better than a larger size? Doesn’t even look like they tried larger headers at all? They may have went faster with larger ones who knows.
Either way still hilarious that I got your panties would up this tight lmfao how sad

Dude how chapped are you that you saw this article, thought of me and then made a novel post about it? Good god I must live so deep in your mind it’s sad

I would have sent Steven (the car builder) your comments, but since you've chosen to be a non-entity, no name, no Vette, no location, no sex (oops, the profile only offers "male" or "female"), you can go back into hiding from everyone.

When I first explored getting headers for my base ls3, which is what this thread is about although some have lost that point, LG Motorsports who does have the dyno charts advised me to go with 1 3/4. Reason being that 1 3/4 make more power in the mid range which is what I wanted. I do not plan to be a drag racer but might take my car out on the road course and I doubt that I will ever do a cam or supercharger. Let’s stay on topic or start another thread if we are debating highly modified vehicles even though this thread was dug up from the dead.
