I have a 89 gt, and I'm bout to start my build.
supercharger 8-10psi
trickflow top end kit
rebuild my stock 302 block into a 347
100 shot of nos.
You guys think this will get me 500rwhp? Will my stock 302 block hold up to this much power.

[fogged306]

With a stock block, thats a grenade. Just depress the throttle to pull the pin.

If you want to do all that either go with an aftermarket block or an older model year 351

and if you do it right, that would be much more than 500rwhp.

The stock block will will work great with that combination until it fails

[kratos2250]

LOL I was afraid of that. Where can I get a bad ass block that can hold this bad ass combination? Or should I go with a 5-6 psi supercharger what would the diff be?

ok the nitrous and blower thing is stupid as shit. you can make 500 rwhp with a blower alone. And the stock block will be a ticking time bomb that noone knows how long it will last maybe 1 run at the track and maybe 5 years we dont know.

If you want a badass block call up world products or dart. But they are not cheap both are about 2500 bucks. and how is this a badass combination you are buying a topend and throwing a s/c on it?

Without the nitrous and a 5-6 psi supercharger you will still be pushing the block 2 the limit.

[kratos2250]

Ok so what should I do? I want a 500 rwhp car, and I want a 347.

[DeMello]

get a bulit block...and im pretty sure nitrous is sorta pointless with the s.c cuz you can just bump up the psi like 2-4 or something and get that extra 100rwhp you would with a 100 shot

[95blackbeauty]

ha

Chose one or the other...charger or nitrous. You might as well piece together a top end if you are throwing on a S/C instead spending the money for the FULL kit that you wont use all of. I def see the block failing if you try and throw all that at it.

2-4 psi is not going to net you anywhere near 100rwhp

[DeMello]

then 8-10 lol

i dont know the numbers or anyhting, im just pretty sure you can increase the psi instead of using nitorus rite?

Why is 500rwhp the magic number? buy a dart or world products block or better yet call coast high performance and order a dominator series 363 short block. then put the topend of your choice on it.

yes with diff pullies

[DeMello]

i mean if he really wants cant he just get a stronger block and transmission and set it at like 25 psi and get like 800rwhp or something like that

Alot more goes into it than that but yes

[DeMello]

like wat besides real end?

i know the TT kits i was looking at for like 7k some wiht the fuel pump and other stuff like that

[Blown331]

The main reason to go with Nitrous and a blower at the same time is not a bad idea. Go with like a wet 75 shot. The reason for doing this is two fold. One-you are taking cold air and compressing it through the blower-we all know when you compress air it gets hotter than normal and then you are sending hot air into the intake. 2-it keeps you from having to run an intercooler/aftercooler and IMO can be more efficient. I am considering this because of that. It really isnt another power adder because all you are doing is cooling the air down when it reaches the combustion stage.

Also. How many miles are on the blcok? Was it modded at all. I know someone right now runnig 9.80's on a stock block with a 76mm turbo. Its a 306 so there is still plenty of block there. I would consider one thing. Your block may be worn down and if it is then you are taking a worn out block and seriously reducing the walls in the block to go with a 347. Go with a 331 if you want to do that.

You would haft to build a car to see what all goes into it. Theres alot of things that you would never dream of.

[DeMello]

yea i heard about the cooling factor of using the nitrous but from wat ive heard you can just get an intercooler to not over heat nething

[kratos2250]

What is meant by peicing together a top end kit. I'll just forget about the nos. I'd rather have a s/c. This is kinda confusing. I know the TF top end kit will produce good power and I like to add a s/c to it. Then get a built 347, and call it a day.

Dont worry about overheating really. I have a V2 S Trim and it works great. The problem is that superchargers get heat soaked right at the motor and the intercooler is a good idea but does not work as well as Nitrous. Also you are compressing air so fast that it hats up at the supercharger so the intercooler becomes useless at that point. An aftercooler would be an idea though. I mean would be pretty efficient as well.
