Well Wiz,

Welcome to the dark side of horse power.

Juice.

Nitrous is like cocaine.

The first hit makes you feel like Superman.

The very next thing Superman wants is another hit.


Soon you will scrap the MAF altogether and go with an aftermarket manegement system, set your rev limiter to 7500 rpm, get a bottle heater, start running 100 octane,........

Ya that's why I left mine in as long as possible. That screen evens out the airflow and smooths the signal coming from the MAF. What's worse is I also moved the MAF really close to the T.B. which will play hell with idling because there is no iac so the idle circuit just opens the t.b. a few % and the idle air comes from the very top and bottom of the intake tube and that airflow doesn't get seen by the sensing element in the center of the MAF tube.


But I got it running good last night and later this week I have a fuel supply upgrade to install and then I will put it on the dyno and see what that was worth. And hopefully this Friday or next we will get to find out what that was worth getting down the 1320.

autowiz Back on task, right now I need to correct my ram air setup. There were some subtle changes made over the C5's life. the 2001-2004 cars used a larger diameter mass air flow sensor. I upgraded to this sensor but because my vararam ram air kit is for 1997-2000 I had to dump the vararam air bridge or 'powerduct' and run a factory part from 2001-2004. Here is what that looked like..



So now that I have been to the track a fistful of times and made a bunch of passes each time I am ready to start chasing power with my C5. First up I must correct this intake setup. I ordered the 2001-2004 C5 powerduct from vararam and it came in. But while I am installing it I need to make a careful modification to the 2001-2004 MAF I am running in my C5.

While I was at the dragstrip this last time as I was getting ready to race I jumped out of my car and raised my hood and removed my engine's air filter. My racing buddy was laughing at me while giving me a thumbs up. And my times were identical and I do mean Identical to what they were before. Absolutely no change. And I want to show you guys why that is. This MAF right here was designed around a 5.7L engine making 350hp at the flywheel:



Yes that screen has caught some debris and to the untrained eye that might seem to be a good thing but I am here to tell you that there is no metallic items caught up in that screen, All of it would have passed right through the big > 2" valves and all of it is only an ever worsening restriction that limits how much air can make it to the engine. So I removed the screen altogether..



And with the right powerduct the MAF is also installed closer to the engine. This most definitely requires tuning and I am doing that on the streets tonight. Here I am all setup with the de-screened MAF and the correct 01-04 powerduct installed..

That is where you have it totally WRONG. You do not have 4 cats. That pic shows 4 cats that have you as their servant. Like I've always said "Dogs have owners and cats have servants"

Logic can only take us so far. Beyond logic is my love for cats. You must first understand that my cats love my Corvette. They respect my efforts and my labors in it..



Really it is pumpkin who loves being out of the house and going for car rides. He likes being in the van also. And because I take him out of the house and I care about his quality of life in return I get a special blessing from him..

autowiz Ya well I am also considering a roll bar / bolt in cage for the vette. It will take me some time to put in but it will make me feel a lot better. I totaled a c3 not too long ago and if it wasn't for the back half chassis I might not have walked away. safety first. Always safety first. Because sh*t always happens. It sucks to bury myself in a few thousand dollars worth of non power making stuff but it will all be worth it when I can be safe at the higher power levels.

1963SS I'm not a drag racer or a drag queen but I think that brakes slow you down, not make you faster. I'll have to check on that. I do recall a Scotsman was asked why he was faster than other drivers. Sir Jackie Stewart's reply was "More gas and less brakes". Also, nitrous is cheating IMHO. If you can't maintain the power via turbos, superchargers or whatever then nitrous is a band-aid. Take that 10# bottle to a road course and run it for 30 minutes. BHP in a bottle doesn't count.

Now if you were driving a big block Pontiac like the Ram-Air IV then it would be a different story. Pontiacs can make 1000 RWHP all day N/A. If General Motors hadn't stolen the LS block design from Pontiac there wouldn't even be a conversation taking place.

Why stop at 150 HP. Go for the 250-400 plates. If you're going to make power, don't finger fu** it. Lay the meat to it. I have heard that a 150 shot on a Pontiac engine makes over 300 HP. That must mean they're twice as good.

The above message from "memory Lane" was brought to you by the Instigator. I had to keep you in your place like our old buddy would. You are getting better and I would really like to see you beat your friend. You need to post more of the pics on projects you're working on. That was some good looking stuff.
