Haibeck Engine Upgrade
 

Is there anyone on the forum that has bought Marc Haibeck's 500Hp engine package who could talk a little about the before and after results?

Are you satisfied or are you sorry you didn't go for one of his larger displacement packages?

Thanks.

He just cleaned up my port work / installed long tubes with Corsa's / set the fuel - I went from 12.75 111 to 12.3/12.4's 115 - given diff in weather track etc I still think his labor was worth .25 sec or more/ 3 mph in the 1/4. I had a 475 LPE job with 500hp cams. He extended my port work from the LPE on the injhousing etc while I was getting the refinish. Ballpark I am around 500 ( will dyno in a week or two) flywheel- I would love to have more but it is not cheap to get beyond the 500 mark:)

Thanks brazilfree. Why didn't you have Marc dyno it?

Do you know if there was anything in your current Lingenfelter build that is not a part of Marc's 500Hp package?

Re: Haibeck Engine Upgrade
 

I would rather have my shop dyno it with me there. The LPE package I have has pistons and rods with the cams - however I think Marc gets same or better performance with his port / fuel tunning etc - IMO

Re: Haibeck Engine Upgrade
 

Just as general info, I believe both Lingenfelter and Callaway did "bottom end" work in the form of connecting rod and piston changes. I believe the goal was lighter rotating mass, and I think Lingenfelter bumps the CR this way as well. And apparently Lingenfelter did some cam changes, or somehow changed the stock cam profiles?

Also generally speaking, and you probably already know this. But I would guess his 500 package makes less difference on a car that already has port work done than on a stock '90-92. Unless you have some kind of freak, or I have some kind of whatever the opposite of freak is, your car is a lot stouter than a stock one. It sure felt stouter than my car with the top end done.

Well...Demps yellow car is a tribute to Marc's work. He ran 168 in the mile at Nellis AFB last fall with just top end work done on his car. Marc and Ted were both proud of it...and rightly so. It was impressive...he was right up there with a fast 368 and almost with the 415 cars. Very Impressive. Marc's work is tops. Maybe that's why he only works on ZR-1s and he makes a decent living at it. Everyone knows his work. He's also working on FU's oil change...and has been for QUITE SOME TIME!

I definitely would have had marc dyno/tune that bad boy if it were me

Re: Haibeck Engine Upgrade
 

Marc, has never done any work for me personally, but I have met theman a few times, seems like a great guy BUT MOST IMPORTANT he shows up to most of the registry club events and SUPPORTS his work, that is worth a WHOLE LOT IMO.

Re: Haibeck Engine Upgrade
 

Marc did the work on my yellow car. It is a horse! I'm not the best driver in the world but the car ran an impressive 168 at Vegas. Marc's car ran a 161, if I remember correctly. In comparison, LocoBob's 368 ran a 171 in Vegas and it dyno'd on the top side of 480 rwhp. My car is lowered with coilovers which helps but it also ran a 12.21 (2.1 60' time) at 119.95 at a 2,700' elevation track. Marc does tremendous work.

Most 350 packages nowadays are only top end. LPE in the day did use Oliver rods plus raised the compression to a 12:1. The cars have a tremendous low end pull. The few I've seen dyno'd around 410 rwhp but like I said have a stout low end.

I would not hesitate to have Marc Haibeck work on my car. Not only does he do great work, he is a standup guy with an incredible attention to detail.

This is another Ted who highly recommends Marc!
Not only does he do great work, but Marc has spent
much of his time helping me with advice and recommendations
and to answer all my questions. I have my close circle of people
I trust for my Z and Marc is one of them!
