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.
Phoenix oooph rough air for sure! Sorry to hear about your friends wreck. Me and Hiossilver are best of friends and we do just about everything car related together including our own work. 150k miles and still running strong is awesome! I will be keeping the stock cam for a bit as I am convinced we can get low 10s out of this thing. Thanks for the best of luck wishes. We give 100% effort with the theory of keeping a real car under us and not turning them into a piece of crap to achieve a number.

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.
Listen I canít help it if youíre some what illiterate and donít understand that 2 - 2 1/4Ē (read as 2Ē to 2-1/4 ď) headers means theyíre stepped. Honestly I think you did bc no one who works on cars doesnít get that. So Iím just going to assume youíre being immature and canít admit youíre wrong (very evident In this thread anyway)

Either way lazer actually calls his car a bolt on car but because you guys throwing a hissy fit over something worth 8hp heís pretty much given up on it. But I do have to admit itís pretty hilarious you posting the rules like theyíre something god himself wrote and are not open for discussion. Iíll bet you were the kid in class who reminded the teacher about homework.

Iím 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 doesnít 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 itís 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

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
Link please.

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".

I have dyno results of my old 1LE with ARH 1 7/8 and my Vette with the tri y. Same basic set ups. I will try and get that posted here for you tonight.

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.

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 itís sad

Anyway yea totally valid comparison....just because a drag car uses 1-7/8 makes them better than a larger size? Doesnít 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

I am soooooo sorry to have bothered you to come out of your cave, but I just thought you'd like to inform these people with all your vast knowledge and experience gained from reading and watching videos in your mom's basement, that they could go a lot faster with bigger headers and there is no reason for a car that makes 1238 hp should be running those tiny 1 7/8" primaries.

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.

Not sure but I would be willing to bet there is 30-40 hp lost in that exhaust set up. He has done a great job keeping the car streetable!

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. Letís stay on topic or start another thread if we are debating highly modified vehicles even though this thread was dug up from the dead.
