I have a chance to buy a Kenne Bell 1500 for my 89 stang for cheap bout 900$ for everything the kit comes with, currently in the process of rebuilding my stock 302 to a 347 going with scat 4340 crank JE SRP pistons, Eagle h beams, comp cams extreme energy cam, racing head service heads, got a main cap girdle, going big for sure, trying to decide if the KB 1500 is too small and if it wont let the 347 breathe, or i am going to go with the performer rpm II, what do you guys think?

If you plan on S/C-ing your 347 you will probably split the block in half, assuming you are running a stock block.

yeah that is kind of my fear right now got a lot of dollars tied up in this lil ride dont really want to split it yet, figured i might just go with n/a till i can scrape up another 2000$ for a new block and bout 3-4000$ for a nice super, then id be set

That sounds like the better plan...

You should ask Dag's (Daggar) about the 1.5L KB. He is pretty smarted about them.

They are nice blowers for sure. IIRC it's about 30HP for every PSI that you add, but the only problem with the 1.5L is that once you hit 9PSI you run out of room to grow. Then you have to step up to the 2.2 and recontinue your quest. If it were me though, I'd buy the blower then put it on eBay and make a nice return on it. Then use that money to throw into your N/A build up (for all the little stuff) and be vary happy....

You will see some gains with it - but not spectacular. The 1500 will not be able to keep up with the air demands of the motor. When I had a KB 1500 on my 302 with H/I the boost would start dropping at about 4000 and up, maybe a 4# boost drop at 13# of boost (13>9). With a 347 it'd be that much worse. BUT if you are running lower boost, it may even itself out. The good news is you really can run lower boost and make more power than a 302, because your airflow is increased over a 302 - and that's good because at lower boost the charge temps will be lower.

I'd say get it and run it. It'll still be fun - you can alwys sell it for what you have in it and upgrade to a 2200 someday. That's what I did.

FYI: it's roughtly 10-15 RWHP per # of boost in most applications.

yeah i have this topic on 3 other forums and its about 50/50 right now, i have almost everything i need for this N/A setup but no intake b/c of this decision on the s/c, i just dont want to starve the engine at low rpms, i was going to go 351 to a 427 and turbo it but just didnt want to cough up another 4-5K for the turbo,,, b/c for what it would cost for a new 302 based dart block can get the 351 for bout the same cash, might just have to leave this on n/a and then start the work on a hatch or notch soon, this is all going in my 89 vert, i have always wanted a twin 427,, sounds like fun to me, just need to buy some stock in chevrontexaco,, do they give their employees free gas,, might have to make a career change

Thats really cheap for a KB. Worse case scenario it doesnt work good on your combo and you can easily get your money back

 

[rugerbp]

yeah it is a steal, my machinst was putting together a motor for this guy that has 4 or 5 stangs and bunch of nostalgia racers he has a garage full of parts he doenst need money so he just keeps all his older stuff, he bought a 89 vert just like mine and bought this for it, then decided that he wanted to turbo his stock motor so he took it off after bout 2000 miles on it and is sitting in his garage along with some vic jr heads and intake, a few 7 qt oil pans, a 351w block (junk i think) and enough parts to piece together another car, he just doenst need the money so i got him to give me a price on some of the stuff and going to buy what i can and share some of my fortunes with some people, gettin the oil pans for 30-60$ each, the heads for 200$ the intake for 100$ and the KB for 900$ might go through and find some more that i want, so that is why its so cheap,, good stuff well taken care of just older man doenst need money and keeps all his stuff

that's way to small of a supercharger for a 347. I bet even with a small pulley you won't see over 6psi of boost. You will be far from splitting the block

 

[rugerbp]

took a look at that super it is a TS 1000-8 its to older 1000 series with the 8lb kit i.e. a pulley,, anyway it doesnt come with ignition boost a pump or anything like that, just the S/C bracket and intake and a fuel regulator, so prolly not worth the $900 for it
