Kinda strange. - ZR-1 Net Registry Forums

These would be flattering comments from my local ZR-1 freinds if it made sense to me. I've got 5 Z buddies in town.SanjayWill BarrettLT5LeeUSAFpilotand ROB93ZR1 on CF.I'll exclude Sanjay and Will Barrett because their Z's are nowhere near stockanymore.But 3 out of the latter hang out on a regular basis and two of which have not only been a passenger in my car but have driven it. And all three have made the same comment "Dude! Your car pulls harder than mine". Same thing happened last monday when Rob and I went to drop his car off at Coreys. We leave Corey's and head to Macarroni grill. And as I'm on the on ramp to the freeway Rob says Ok man put the hammer down. I want to see what your car has. I do. And he says the same thing. Your car pulls harder than mine and he says and thats with his big 300lb fat azz in the passengers seat. I told him I don't know how thats possible. He's got the 405hp LT5 with a B&B exhaust Haibak chip and 4:10 viper gears. His car dynoed at 368rwhp. He says I don't care what I've got your car accelerates faster than mine. And of course he points out the fact that I put that Fidanza on and I've ported my top end which makes a difference. But before I ever ported the top end USAFpilot and LT5Lee said the same thing. I know for a fact I'm running stock 3.45 rear gears. And I know that no engine work has been done to it so I don't know? Maybe it's just really good running Z. I don't know what else it could be. I decided to wait and get it dynoed after I put the headers/bullet cats on and have it tuned. Then I'll see what kinda hp #'s it's really putting out.

Maybe his secondary actuators are installed backwards

rhipsher · 01-05-2010

Then that would mean all three of their secondaries are installed backwards. It's possible but I highly doubt it. And since Robs car already dynoed 368rwhp I would think it's safe to say his secondaries are functioning just fine.

GOLDCYLON · 01-06-2010

I disagree. They will still function if installed backwards but the throttle response will be slower than if they are installed the right way. Just a thought since the information provided was that you seem to have the "jump" on your friends when you punch it.

This was a reported problem many years ago and reported in the older registry maginzines. A lot of them were reinstalled backwards probably by GM dealers after a maintence procedure. A lot of members noticied an immediate improvement in Throttle response when returned the correct way. Just another area to check. GC

Well I will be able to determine that soon enough since I'll be doing a complete tear down/top end porting and re assembly on his 93 Z in trade for a brand new set of CCW rims. 13"wide rears and 11" fronts. They are some sweet looking rims.
But I digress. What are the odds that three different year Z's 91 93 94 would have their secondary actuators installed with the actuator arms 180 from where they are supposed to be?

I think its a combination of things. You may have a real stout LT-5 and perhaps they have a few issues with their cars or perhaps they are just pulling your leg

Just be glad its a strong one

rhipsher · 01-06-2010

You may be right. I guess it will just have to remain a mystery. If your gonna have a mystery, I suppose thats a good one to have.

Also everything feels faster from the passenger seat.

Not if my wife drives. She could make the fastest car in the world feel like a dog. Shifting at to low of RPM's and bogging it down until it just about stalls.
But I would agree with you about feeling faster from a passengers point of view accept for the fact both of them drove it. I don't ask to drive others Z's because I know how anal some can be about it so I don't have seat time behind the wheel of numerous other Z's to compare it to. So if thats what they say then Ok. I was just wondering if there might be a reason that would cause there to be a slight difference in performance. No big deal or anything.
