Vette73 - a Marc Haibeck chip comes highly recommended (I have had 2 in my current and previous ZR1s), and this certainly helps... next would be exhaust imho as bang for buck and easy to do... K&N air filter helps, yes, but so does a clean filter.

I respectfully disagree. The LT5 utilizes a MAP based engine management; not a MAF. Therefore they are much less tolerant of that type of modification w/o a tune.

Anything done to change or improve the air in or out, really requires tweaking of the calibration. So, to buy a "chip" from Marc or anybody, and then go out and install headers, or do some porting, etc, the tune is affected. Buy the chip WITH the calibration for headers BEFORE installing the headers, was my point.

MyZR 1 came the other day from gateway classics in Chicago...
Never in my life did I buy a car sight unseen....

I have to say the car is super clean...Really really nice Black ZR 1..

If you google gateway classics corvette # 633 you can
See it.....I think it's still on the website, a video also..

I would def like to do some mods to the car..However,never
Had a car with this much technology...My 73 convertible
Is super clean and I have a worked 350 in that..

I'm looking for low end and throttle response with the ZR 1..

I won't be doing any real high speed driving...I mean,
At times I will punch it on the highway but not crazy..

I see a few of you have conflicting theories on
Modifications ....I had the car out today and it's
Got balls,it does ....

My thoughts are.....Chip,cat back exhaust,
Hi flow air filter,Allthough I checked-there is an
Amsoil filter in there already, and maybe some gears
After the winter....

Any input is appreciated....

Tried loading some pictures of car in my album
But photos did not upload...

I recommend a green filter. I don't use k&n anymore. Green uses a better filtering method although similar and I don't mind giving up a tiny bit of power if any for slightly better filtering and still flowing much more than stock.

As for low end torque, perhaps you bought the wrong car !! With long gears (same as LT1) the LT5 in my opinion will always gain more up top with mods like porting and headers etc. I don't personally like gears... but if you want more snapping torque... 3.73s or 4.10s are my suggestion.

I have a long thread not sure if most will interest you but I did headers and exhaust in there and Im really happy with the gains.

headers yes, exhaust you don't really need a tune for

Well I wouldn't say the car has no torque, I mean 370
Ft lbs is not that bad...Granted it's up in the RPM range,
But after driving this car most of the day today and really not
Taking it past 5,500 rpm I am happy with it..

Response is nice and when you hit that gas it moves...

My 73 has 390 ft lbs in the crank at 3200 rpm so
There's a good amount of torque in that motor..

A big reason why I bought the car is you just don't
See them AT ALL.......The little characteristics that make
It unique attracted me...The wide rear , the slightly wider
Doors and the huge tires in the rear...

Very nice blue color on your car....Very unique..

the zr-1 makes over 350 ftlbs of torque at 3000 rpm and around 320 ftlbs at around 2000 rpm. It doesn't feel like it but it has 300ftlbs at 1000rpm

Dyno graph from my testing years ago: Average torque up 3, average hp up 5

Default Re: SLP Cold air intake....Worth the money?

Headers, exhaust, intake porting are the big three power adders that don't involve buckets of money and intrusive engine work. A tuned chip makes the most of the big three.

This is correct. You would be very happy with these mods on your car. Dont blow money on your gears either. It will impact your top end speed which is where these cars shine and the grunt off the line with the 4.10 gears will just result in spinning tires. I have the stock 3.45 and a bunch of mods and it gets off the line just fine. Once you have the those mods done maybe a fidanza flywheel so you can rev up much faster.
