i have a 89 305 tpi car with an auto and was wondering if there is any other emissions controls on the car that can be removed because we dont have the vehicle emissions testing here in kentucky any more if u no tell me thanks.

 

*thinking wheel of fortune*

can i get a comma please!?!?

NO

can i get a freaking period then?!?!

Jeez camarokid.. you have been posting a ton lately! Not that it is a bad thing..
But to answer your question; There are a LOT of emmisions crap on your IROC.

 

i no ive been posting alot im only 15 and have alotta questions i cant ask my dad any more because he just gets mad because ive asked him so many so i guess ill ask you all

 

LOL.. NO KIDDING?? MY DAD HAS GOTTEN TO PISSED OFF TO ANSWER MY QUESTIONS NOWADAYS TOO! lol. I am 17.. started off on this board when I was 15 as well Just cruise this forum, the suspension, brakes and chassis forum, and you will be good to go
But trust me.. learn the suspension as well. I know a LOT (well, I think so anyhow..) about engines, but ask me a detailed suspension question, I am totally lost. I know the basics.. but nothing in depth. It's like I am starting to learn about Engines all oever again, except that it is Suspension, lol.

 

You could do the coolant hose bypass mod, remove the AIR pump and have the headers that don't have AIR provisions. EGR doesn't net much, if anything. Also you need to have the EPROM reprogrammed so it doesn't throw a code.

I see you are considering the LT1 also. IMO, it is too much work for too little gain. The only savings I can see are the reduced drag of the distributor and the reverse cooling. AFAIK, an LT1 and an L98 maxed out will show that the LT1 makes about 20 HP more because of the 2 items mentioned. IMO, it is not worth the hassle. I am making about 410 at the wheels with a 383 SB, AFR 190 heads and custom cam and the Holley Stealthram.

 

Well the other benefits, that weren't mentioned are a better PCM, the stock factory heads worked over can support bigger numbers so no need for aftermark. And both engines maxed out being 20hp apart. stock for stock LT1 is better, mod the heads and a cam and the LT1 is better. exhaust LT1 is better. Tune the engine cheap and easy from pcmforless.com and it's better.

Granted some things the L98 is better. some parts are cheaper! more plentiful selection of Aftermarket heads.

it all depends what he wants. LT1 swap is getting simple and easy to do. and the gains are very nice.

 

So you mean to tell me that with a stroked shortblock, a set of custom aftermarket heads, an aftermarket intake with jack for hood clearance, you can make about the same power as a stock LT1 shortblock with ported stock heads, a stock intake, and a cam matched to the heads, man yeah, who would want to get the whole better engine for little more than the cost of that stealthram........

 

Hey camaroz28racer2, the Stealth Ram is $507 you tard. Show me an LT1 that makes 410 at the wheels for "just a little bit more than" $507 and I'll personally pay for you to send me your shoe and I'll make a video of myself boiling it and eating it and mail it back to you. Also, I've seen AKLIM's dyno sheet. A ported stock LT1 isn't close to his power.

 

I have no doubt Aklim makes awesome power with his combo, AFR heads a really nice and I like the stealth ram as well, know a few people with them and it's a great intake.

but the intake in now way give you the power, you left out the fact! that he has a set of AFR heads and a Custom cam.

I was trying to point out that you can get stock LT1 heads worked over nicely, and a Cam to match, with your standard bolt ons (and Im pretty sure Aklim would have bolt-ons.) and you can make very close to 400 @ the wheels, just do a search on the boards.

 

It's gonna take a lot more than just a 507$ intake to make that 410RWHP. He has AFR heads and a stroked short block. By the way, the stock intake on my LT1 can easily support that HP level and more. And I can get a used one on Ebay for $25.

 

if you were to spend a little more time in LT1 tech you'll see MANY guys making 400-420rwhp with ported heads and cam.... on STOCK BOTTOM ENDS and LT1 intakes. i've seen a few 383 LT1s with AFR heads break 450rwhp on pump gas and LT4 intakes.

One thing you L98 guys have in favor for you is the readily available heads. If i had a third gen the first thing i'd do is build a 383 or 396 and slap some Brodix 18X heads and intake on it. You could make over 500rwhp with those heads easily on a hydraulic cam. Or if you're insane, go for a 15* or 14* head and make even more power. I don't understand why more of you guys don't do this when you tear into your engines. I'm jealous that i can't use these heads on my LT without the conversion work.

 

Where did I say that an LT1 would make 410 rwhp for the price of the intake ?

Ah oh yeah, i DIDNT, i said it will make the same or more power on the Factory manifold and factory heads, after being ported, with the factory shortblock and a custom cam,

He has a LOT more than just his $507 intake manifold, add in the AFR heads, 383 shortblock, the hacking required to fit that intake under a stock hood, or aftermarket hood, then the fact that the stealthram equipped car couldnt even slip past a visual inspection since it doesnt have egr....

 

on a serious note. Thats kinda sad. I have a daughter, and cant wait to have a son that asks a ton of Camaro questions.

 

BTW, my heads and intake are basically bolt on from the standpoint that the heads are AFR 190s and have not been touched other than with stiffer springs for the lift of the cam. The intake has not been ported either. If I were to port them larger to say 195 or 200 specs and also port the intake, I could be seeing about 540 at the crank. I estimate about 20% loss with an A4 which makes about 513 at the crank.

Yes, it won't pass emmissions. So? camarokidirocz said he is in KY where there is no testing. It can work. I think you only have to cut the bracing on the hood or in my case, I have a ram air style hood because my stock hood kept hitting the TB when I had my Accel SR.

I do agree that stock for stock, the LT1 is going to be better. However, that is about as far as it goes. So, if he wants to just throw in the LT1 and run against an L98 that is stock, he has an advantage. However, when you go further, and most of us will, it will reach a point where the gain is meaningless. I know that I can get maybe 20 HP if I wanted to rip out my stuff and go to an LT1 but if I am not racing for a career, I could care less about making the extra 20HP for a lot of work. Another thing to consider, many of us started out with small stuff and finally worked to bigger things. I started this whole thing with a 240 HP (yeah, right) engine at the crank thinking it was all I would ever want. Then came heads and cam and the rear end and I swore I would stop there. Then came the stroker motor, beefed up tranny. Then came the intakes and different cam. Now I am thinking that if this motor breaks, I will rebuild it with a low compression set of pistons so I can supercharge it. My point is that you might want to build it with growth in mind.

You can work the stock heads over but by the time you get a professional job done, you are already at the cost of a set of AFR heads and more. Take a look at what LPE charges for his reworked L98 heads. Now, if you want to grind and take a gamble that you will come to something close to what you need, that is another story. With my heads, I could get them cleaned up a little and they would flow as much as I needed for my applications
