Hey

I have a 1985 IROC Z Camaro with the 305 TPI engine and 3.42 gears. The car is pretty much stock except it has a ADS chip. I want to get my car into the low 13s for now. I will be running street tires ( BF goodrich ). I have some mods planned but im not sure if they will get me there. I plan on getting the following:
- Headers
- Catback exhaust
- K&N filters
- Airfoils
- Transgo shift kit
- Corvette servo
- AFPR
- high performance plugs and wires

Will that get me to high 13s.... Im looking for 13.7 - 13.9. If u have any suggestions to pump out HP let me know.

Thanks alot

I don't think you'll see high 13's with those mods with a 305. I have pretty much the same mods as you the difference being mine having the 350 with 3.27 gears and I generally run in the 13.90- 14.05 range.

You may see some low 14's with a good launch,
By the way, the car looks good.

Gut your air box, rip out your maf screens, take your smog pump off, and do the mods you say you will do. I would ceep the cat off though that might get you more power. Dont speed to much money though if you plan on moving up to a 350 sometime. Just to those mods plus the free mods above and then save for a 350. Hope this helps alittle.

If you will ceep that 305, then put some headers on it and a intake.

 

Add a nice Torke Converter to that, and youll be 13's no prob. My vert pulled a 14.5 with a shot to hell clutch, and 2 bad injectors, so there is hope. Mods are in the sig too...

 

Im a bit Sketchy Myself as to weather or not you will get into the 13.x's with a Peanut Cammed car, No matter WHAT you Do to it.

However, The list of Mods you Have got goin There is in the Right direction, Add In a mild self port on your plenum, Runenrs and base to Help even More.

Its really hard to say with the Peanut cam and the 85 TPI. Im not even going to hazard a guess.

 

Good point... I forgot he has the peanut cam... get that outa there ASAP.

 

This is what I did with My Peanut cam...



It Helps keep the Floor Down.

 

Heh, I got a better one... heres what I did with my stock 350 cam. I took the pic by accident, but when I saw what I had taken, I just couldnt resist!

 

Lol thats great.

We should make a photo essay "Salute to the Peanut Cam"

 

Hey

The peanut cam came out in 1986. As any guy on here with a 1985 305 TPI or vette 350 TPI. The Cams in 1985 were pretty good, Guys that do a cam swap on there 1985s barley notice a difference.

Do u guys think that my car will hit 13s or not...

De we think you will hit 13's?

With those mods I would say that it would be a better bet to see low 14's on a good day.

I just finished a mild buildup on my motor today, new 10.3:1 pistons, .500 lift cam, stock heads and TPI for now, 2000 stall, AFPR, 3" exhaust, 1 3/4" headers, flowmaster, 3.73's, Trans Go, K&N, Gutted MAF, Gutted airboxes, (Ram air soon).... Uh I think thats it. Thats on my 350 .030 TPI. I hope to see high 13's with this combo. But a mid 13 would be great. You need to do a lot of stuff to get these cars into the 13's. All it takes is money/elbow grease I guess. You also might want to look into burning EPROM's for yourself on the DIY PROM board. I hear there is a lot of power to be gained by simply tuning your engine.

 

You have a start:
- Headers - TES
- Catback exhaust - RPM
- K&N filters - yes
- Airfoils - in the 52mm TB
- Transgo shift kit - definitely
- Corvette servo - yes
- AFPR - & FP gauge
- high performance plugs and wires - see below
Now add:
-hi-flow cat
-HyperTech coil/cap/rotor
-cut-back plugs
-160 deg stat & fan sw
-underdrive crank pulley
-TF heads (yes the valves clear in a 305, though slight shroud)
(and these shave about 40lbs off weight)
-better cam & valve train (stay mild w/ 1.6RRs to maintain low torque)
-2,400rpm lockup TC
-BFG DRs, to hook up
-SSM SFCs, to reduce body flex and hookup better
-LCAs, same as above
-RamAir tubes (behind fogs into K&Ns)
-gutted MAF
-52mm billet TB w/ integral air foil
-BM base & LT runners (port matched to heads & plenum)
-(I'll post my results with siamesed base for a possible cheap alternative to this $800 mod)
-ported plenum
-lose the spare & jack (-50lbs=-.06sec)

Check out my mods/results & remember that my IROC is very heavy (nearly 3,800lbs at launch); every 80lbs off is worth about .1sec.

 

I ran my car at a track in OH yesterday. First time this year. I did a 2800 stall and 3.73 gears a couple months ago. My new time is 14.7. I gained .4 over last year with those two upgrades. In a couple weeks I doing the LT1 intake swap, LT1 cam, Torquer heads and 1.6 rr.

What do you guys think I'll get down to in the 1/4.

 

port out intake plenum (go to tech section on this site), put exhaust cut-outs right behind headers, (good for up to 30hp.)

 

Hey

Are u serious that if u put exhaust cut outs after ur headers u can get upto 30 extra HP.... Im not sure about that, how does that work

P.S are exhaust cut outs new peices put into the exhaust or is it a hole cut in the exhaust

http://camaroz28.cardomain.com/id/56424

 

Theres no way cutouts can give a gain of 30 hp... 10-15 MAX. Cutouts are pieces welded into your existing exhaust, and allow you to uncap the exhaust.

Ron Mullins: Your numbers seem very low compared to your setup... how is the engine tuned? You should be pulling low 14's to high 13's with your current setup...

 

I haven't done any kind of tuning other than bump up the fuel pressure a couple psi. What do you recommend? I have heard several people say that about my setup but one gives me any other tips. Timing, TPS??? I know if I can get it to hook up I should get at least low 14's.

 

First off, I would get your timing anywhere between 8-10*. Then, I would experiment with the fuel pressure. 48 psi seems to work well for me. Do you have any type off chip in there? If not, I would recommend a chip from FastChips. Pretty pricey, but it should definatley wake up your engine. The other thing holding your engine back is your whimpy cam. Dont take that as an insult, but the factory cam in your car isnt worth a ****! You have a VERY good foindation to work with!

 

In a couple weeks I am going to do torquer heads, LT1 intake, LT1 cam, 1.6 rr and an Ed Wright chip.

 

Mods in the sig should get you to where you want to be

 

I am no expert or anything, but with the little bit of info on what your future mods plan to be I dont think you will be hittin 13's any time soon. All the ideas up to this point will get you there, but if your anything like me you want instant results spending the least amount of cash. Have you thought of installing a Turbo or supercharger kit? Either one of these with a decent amount of boost would sure go along way in getting you to 13. And after all the ideas I have seen on this post boosting your engine also seems the cheaper route to go. Hope this helps.

 

You're not getting into the 13's without getting into the motor (ie heads and cam). And if you do that, i'd suggest looking at some of the aftermarket tpi intakes or porting your existing intake.

 

To the original poster. No, you're not going to hit 13s w/ just those mods. You'll likely need a good converter and teh ability to geta good launch. A little porting on the intake is a good idea too. More than a few people have taken bolt on 305s into the 13s. I plan on it.
