Not everyone goes tho the drag strip either... lol. I'm making 550 whp on a 427 NA build, with 32 stall. I don't know what it runs in the 1/4, but that bitch is fast. STUPID money into that car. Just don't want to have to put in a cage and all the other ****. Always been more of a street guy personally.

Which runners you have in the fast?

Just checked your album out....LOVE the gold. Don't see those very often.

ChopperDoc

Stock runners with spacers. It doesn't make a ton of difference, because pressure is pressure, and it's just an NA build. Also running a Walbro 255. My family is in Gloucester, along with all cars. However, I am in the middle east at the moment, doing America stuff.

Crazy how Doug hasn't told ChopperDoc that his car sucks for only making 550rwhp with 427ci lol hypocrisy at its finest.

ChopperDoc

Looking forward to the part where I care. Didn't know it's a dick measuring contest. To each their own at the end of the day. I just like building cars,and other things. That is when I don't get to shoot ********, which is something else I actually enjoy doing... LMAO.

ChopperDoc

Here is some ear candy of that thing idling...

ChopperDoc

Thanks man. Appreciate the compliment. I loved it too. bought it back in 2003. SO much has changed since then. Did the LS3 swap way back in 2008. May of been one of the first few to do this, actually. I will say there weren't any guides on it back then. I didn't know what I was doing at the time to be honest. But I made it work. More recently, I broke the 60 again, sooooo, as anyone would do, I went ahead and pulled the engine for an "in depth oil change" while I upgraded to the 4L80. Yeah, because reasons. lol. That's what I told the wife, even though I even got her to help lol.

The runners do make a difference especially up top. That thing is no doubt dying for more intake. I'd probably shove a sniper on it tho because it fits a fcar vs something like a lod x1 or highram.

Phil and i picked up about 40whp on his h/c ls3 c6 with the lod x1 recently. You engine is severely intake limited right now imo. You could easily go over 600whp.

Look at mac being a bitch.

Hiortez ain't talking **** to Chopperdoc because it's hard to hide behind a keyboard when it's that close to home.

Nice.....sounds good. The gold is so cool. The black fits it well to break it up a bit. It probably was one of the first ls3 swaps back in 08. 80e should have no issue holding up.

ChopperDoc

That's some really good info. I built this about 4 years ago, and FAST was the thing back then. Didn't have a lot of options out there. What I have seen with most intake comparisons done on engine dynos, the intakes only were good for about 10, maybe 15 HP between the stock one. But still, that's a gain, so hey I'll take it right? Of course this was from magazine articles and so forth. Things change.

What I really wanted to do, but missed the opportunity due to having already purchased the intake and had the heads milled, was go LS7 heads with 102. That probably would have made this thing make a ton more. But yeah, missed a chance to pick up a set for $1200 because they were "blemished", as in repaired in a non-critical area by the head shop, but could not be sold as new as a result. Should of grabbed em lol.

I will definitely look into that though. It's done for the moment. I have no issue with the fueling, with 80# injectors I'm seeing no more than about 70% duty cycle at WOT, which is fine by me. WB numbers look good too. The real limit was the stock pump, because it dropped to 40 PSI above 4000 RPM, so the Walbro 255 fixed that problem. I haven't ran it over 7k though either, so perhaps it would run out at some point. My current redline is 6800

Beautiful car ChopperDoc. I don't think I've ever seen that color in person.

SoFla01SSLookinstok

Awesome! Thanks for all the info on your car. Gonna take a look at the pics & see if pics of your custom intake track. Also what vacuum pump are you running? Beautiful car & combo.

This is quite odd of how duhg is being so nice. Even though he knows engine size & rwhp numbers. It's good though. Also if you're not planning on spinning much higher than 6800 rpm the manifold you have is probably the best.

ChopperDoc

Thanks man. I love that it's different. Turns out only 315 gold Z28 Coupes were ever produced, so I feel pretty lucky to have a relatively rare one. There are rarer colors out there, but I have what I have. Definitely turns some heads, especially with the cutouts open lol.

Pro tip: don't leave the windows down in the tunnel if you plan to stab the gas with cutouts open. The pressure wave will pop your ears. It's crazy loud. Ask me how I know.

SoFla01SSLookinstok

Should have looked first. Lol. Very nice intake. Also I see you have the GZ pump. The smaller pulley makes me think you have an under drive crank pulley/balancer? How long have you had the pump? Do you have a vacuum gauge hooked up?
