Let'* take another track here.

I just got off the phone with one of the ZM L36 test cars. I asked him if he'd trade what he gained on the low-mid range for a ZZP HV insert now, knowing the HV loses a little bottom end to gain on the top.

His 5-second reaction said a clear NO.

The L36 (in comparison to the series 1) was designed to gain on the top by free-revving lighter internals. The L36 already has a leg up on the top end. Now you can gain low-mid range. Get it all.

Why?

A tenth of a second on the 60' times at the track equates to a 2-tenth advantage on the ET. Why would you give up what you just gained from the LIM on an HV insert that only gains on the top end? Your ET will suffer, but your trap speed will gain.

You make the choice.

Because your only in the low end and mid range once. From there it'* all top end.

I really don't understand what the point is to compare a port matched LIM to a shortening of the intake runners? They do completely different things to the intake track.

When you're talking about performance at the track, what you do in the first 60' or the first few seconds in each gear means more to the ET than anything else.

That'* why your 60' gains mean a 2:1 advantage at the trap. The L36 ALREADY HAS a great top end. Now let'* gain back that bottom end the Series 1 had. Without giving up ANY top end.

I still don't see the point of comparing the ported LIM to the HV3 and suggesting that a ported LIM will net quicker times.

The L36 has a great midrange.

I can't imagine you'd have a SLOWER 1/4 mile time if you added the HV insert (Personally,I wouldn't add the HV without ER rockers too), but you could very well have a slower "street" car.

Am I on target there? I guess it depends if you want the best 1/4 mile time or the most fun stoplight to stoplight.

Edit to clarify: Bill, you're talking about putting an HV on top of a Ported LIM vs a Ported LIM?? That'* what I based my comment on.

I don't know about you, but if I had an L36, I would much rather improve my ET than my trap speed. *shrug*

To each his own.

I mean as far as low end goes, with my old setup, I had a 13.6 L67 regal through an intersection before he started pulling infront of me. How much more low end could you need? And that was with the old shorter HV insert.

uhhh ok? Don't know where that came from? Never said anything to suggest that.

Remember, we're talking specifically about the L36, and the fact that it has less low-end than the L27, but more high end than the L27.

So, since the L36 already has the high end, the ported LIM gives it the low-end back. So, talking only about the L36, it will benefit more from the ported LIM, and less from the HV than the L27, and especially more than the L67.

Fohhh-cuss.... :P

No offense, Mike, but you didn't have a stock-L67-off-the-line killer, especially against a 13.6 second L67 Regal GS. He either had no traction, or he wasn't interested in the challenge.

The point being........one of the LIM test cars wouldn't trade PART of the low-midrange grunt gained for more toip end.

That'* not from me. That'* from a car with the ported LIM.

Oh I did.
He'* a good friend of mine and he will admit the same.
I don't bullshit. Find me one other time when I did. I have nothing to gain.
