GTO TOO

I looked at the hood.

 

GTO-TO-GO

More air (cold) into and out of the engine at any RPM will get you more horsepower. As long as the ECU can keep up by keeping the mix correct(not to lean).
Cheep----- K&N filter with after cat exaust.

Bucks----- Hi-Flo cold air intake with supercharger and intercooler with fuel management and headers with complete dual 2 1/2" exaust.

With the money you can save on a 2004 before Nov 1st, do the bucks upgrade and blow the doors off any 2005 that might pull up.

A good supercharger kit should give you 100+ hp to the rear wheels.

SLP's ram air hood is functional, sealing to the oem air box.

they call it "ram air" but really it's more of a a plenum when compared to real ram air muscle cars of the 60's & 70's

now , this is good topic here, and it was and is also, on the SS owners forum.

for my 02 SS Camaro with the "oem" SLP ram air hood, it added 10 hp on paper.

but all the discussions, inlcuding that of SLP engineers, was that it only helped at high speeds as the fbod's were "bottom breathers" similar to the GTO

I noticed gains on the SS (seat of pants & dyno) by dremeling out some plastic that restricted air into the air box, K&N filter, and smoother air lid (MTI Clear) They were each small but still a gain. Also had exhaust cut out with electric power plate. with cutout open lost a little on the bottom, but gained more at the top. cutout was after the cats but before muffler

Wrong again !! see above. If you were to unblock them, they are holes straight into the engine bay. I would hate to see what the engine would look like after driving in a rain storm ... [quote]


That was my main concern. And how do the "Ram-Air" GTO's from the '60's address this problem?

westell

don't know about classic ram / rain concern

SLP's have a couple drain holes at strategic locations

You may want to look at these. The scoops that are on the cars coming out are going to be open. Even though they do have the honey comb look to them, they are not blocked off. When you will drive in a rain storm, you will get a little water in the hood. Whether or not it makes it to your air filter is an entirely different subject for we don't have answers yet.

The electric cut-out sounds like a good idea. I had a QTP electric cut-out on my 02 Camaro with a SS hood.

I am new to the forum but not new to F-Bods and want to mod my 04 GTO.

Saying to sell the 04 and buy an 05 was joking right? That is silly of course. I can't drive a totally stock car hehe never have been able too.

I'm sure there is a way to get some more power out of this car without going FI or N20 and I was looking at exhaust and air intakes first as I always do.

I haven't looked real closely into this yet but their has to be some restrictions in the intake and exhaus somewhere?

Also are there any ECU mod's out yet or does this ecu learn pretty well when you adjust the A/F? I had the Hypertech on my prior F-Bods and loved it but I guess it isn't made for this car.

I had an 01 Pontiac Firehawk that loved modifications though and it had lots of SLP stuff on it straight from the factory.

What did they change from the 04 to the 05 to get that extra power does anyone know? Anyways that is where I will start by reading the exhaust thread links posted (thanks) and lurking here and reading.

Wanted to make my first post and say hi to everyone though.

The 2004 has a 5.7 LS1. The 2005 will have the new 6.0 LS2 (same as the vette).

GTO-TO-GO

Any Corvette engine or ECU upgrades should work for the GTO.
