Im pretty irritated. My friend has a 1992 Z28 that is completely stock. I have a 1992 RS. My car has been modified with the following things.
Swapped in 350 ZZ-1... (rated at 345 hp supposedly)
Edelbrock alluminum heads....
Crane cam....
Edelbrock TBI Manifold...
350 injectors.....
Streetfighter 700r4 Tranny....
Breakaway converter...
Hooker Catback
~When we dragged I jumped in front by nearly a full car length. After second gear hits she passes me and just blows me away. With the mods I have I thought I would win, or at least be equal. But no....she didnt just win....she kicked my A$$
The only difference I can think of is that her z28 has a TPI system and Im running on a TBI. Does that really make that big of a difference?

 

Are you running a stock chip?

My untouched, bone-stock TPI Z28 is still faster than my modified TBI RS, so don't think you're the only one.

 

thats pretty funny....lol she beat a he! does she go to these boards.

 

I am still running on my original 305 chip. It runs strong, but apparently not strong enough. Both times we raced I instantly jump in front. I dont know if maybe I have more torque or if its driving style. We both just ran in regular D so neither of us shifted from 1st. What could be making my car so much slower?

 

Get a custom chip.
My 92 RS smoked a 98 Cobra the other day, three times in a row.
It's a 350 with TBI also.
My chip's from Ed Wright @ Fastchip.com
Other mods in my sig.

sounds like you need headers. are you running stock 305 tbi manifolds??? was her car a 350??

 

Yes her car was a 350. Should I not think about going the direction of getting a TPI system?

 

and yes I am running on 305 manifolds.
which way should I go to get headers. There arent to many for me being Im in Cali. I know edelbrock has some but I havent heard to many good things about them.

 

I'm no mechanical genius but it sounds like some headers and a better intake setup would help your engine breathe better.

 

The cam that I have in my car is a Crane CompuCam with the part number 2010. Would someone mind going to the Crancam website and taking a look at this. Should I have gotten a different Cam. I have another cam that came out of the ZZ-1 engine. It is a higher lift cam but my car wouldnt run right with it. Something about bad vaccuum.

 

From what I can see you have three problem with your setup:
1. The cam you have is extremely small 184/194 .384/.407 106 @.05" duration. You are right; the ZZ1 cam is a probably bigger than you want to go. If I were you I would get the Crane Powermax 2031 208/214 .438/.452 112 @.05" duration.

2. You need headers bad, the stock 305 TBI manifolds were some of the most restrictive put on our cars.

3. I would at least try to find a stock 350 TBI chip. If not a custom.

A 92 Z28 is rated at 245hp and 345 Torque.
With that set up a stock 92 z28 should stand NO chance against you.

Emissions legal headers should not be hard to find, just look through Jegs or summit you will see quite a few. The cam that I mentioned is also emissions legal.

 

So a chip, headers, and a different cam is all I should really be worrying about? Is her TPI on her Z28 making that big of a difference compared to my TBI?

 

That was fast..
No, the TPI is not making that much of a difference. On the Camaro Z28 message board I think someone made swap with a 305 and dynoed it, not sure but I think they picked up about 13rwhp. Considering the swap will cost around $800 I don't think it is worth it.

 

I agree completely. That's why headers and free flow exhaust should be among the first mods done.

 

Thanks guys....I appreciate the help. Its just hard to see my camaro with about 10,000 dollars into it including buying the car lose to a z28 that cost 6000. Thats the ****s though.

 

along with the already mentioned, you may want to go with a larger throttle body. your also cfm limited right now.

 

Do you guys think it would be a smart to go with a Holley 670. There is a local hot rod shop and one of the guys told me that it would be a waste to get it. Im not quite sure if he is honestly trying to help me out or get me to spend money at his shop.

 

Well, at this point, getting into burning your own PROMs would probably give you a better gain $/$ than getting the Holly 670.

Just curious, what stall speed is your converter?

 

I have a tci breakaway converter. 1000 stall speed. I think its suppose to be 1000 over stock. How do I go about burning my own proms?

 

Right now I would just worry about getting headers and a new cam. I would try to find a stock 350 chip to run your setup. Getting into prom burning is not easy, takes a lot of time and effort to learn, I am in the process.

With the cam and headers (If you don't have a catback you will need one) you should see a major increase and the CranePower max 2031, or similar, should be able to run off a stock 350 chip pretty well.

After you have this I would then consider a larger TBI and a custom chip.

By the way is this a daily driver or more of a strip car?

 

as of right now its a daily driver and a strip car. Within the next month-month and a half Im going to be getting a Acura CL. I am not planning on getting rid of my camaro though. When I have another car to use my camaro will be more of my weekend car. I did recently put on a new hooker catback. It is only a little louder than it was stock. Although I can feel it having a little more sotp go.

 

what should i look at as far as headers go?

 

SLP, Holly Hookers, SLP, Edelbrock TES, and ummm SLP.

 

Sounds like you need to spend some time reading on the TBI board.

I also agree with the above ....cam, headers, 3" exh, intake and start with a chip from a 1989 Cop car version of the Caprice that had a TBI 350. The chip code is ANLU. This should get it running better with more fuel pressure or bigger injectors. It will be a starting point for tuning from there.
