It's a marince motor but still impressive for the lowly toilet bowl injection don't you think?

 

600 horse on a BLOWN 502?!?! Are you nuts?!?!

That's only 90 more horse than a N/A ramjet 502 makes.

 

actually that is quite impressive.

because it is a marine motor, you are able to get 600 hp at a constant rpm for as long as you want, untill something blows.

being in a marine environment you have to keep a constant power output otherwise you slow down in the water.

 

Considering you don't know much about the motor other than it's size and if it's got a power adder.....I'll pretend you didn't say anything and you can start over again. No sence in me going off on you because you think the blown TBI 502 is at all similar to the ramjet 502, that's just silly.
The fact that EFI needs to be durable and perform well in a marine application makes this a very practical engine. This wasn't made to be a flagship motor, it was just your mild reliable blown 502. If this needs to get messy I could tell you that I know of a few 502's running a blower and carb that aren't making even 500hp. Until you know the nitty gritty I wouldn't be so quick to dismiss.

 

Must be some sorry 502's.. BW

 

The dude is right. 600hp from 502 blown cubic inches is kinda sad...I don't care what it's for.

 

It's 600 + hp, not just 600. There is also the 700 + hp 540. Who's to say what kind of ratio they're running. Honestly what is the big deal? I just point out that it's a TBI power adder and you guys put on your "tbi sucks" hats and go to town. It's probably so mild because they don't have enough fuel! They're not using dual 4 barrel TBI setups, they're using 2 2 barrel GM with BBC injectors I'm sure. If you do the math I'm suprised they're even getting 600hp from it. You should be too.
Go to that page now that it's working and just LOOK at the damn pulleys. They're huge! Or am I the only person here that's looked close enough. Please do tell me why it's so unimpressive AFTER you've looked at the big picture

 

Nobody has said ANYTHING about the form of induction, Jon.

Please don't go on another TBI vs. The World rant.

You're right, I am suprised that they're getting 600 horse out of it. I would have expected more.
No hard feelings, don't take it personally against you or TBI. Tell Black Echo that I love him.

check out the size of that pulley, too bad you can't see what's on the crank but I'm sure you get the drift.
If I need to prove more I will but it's plane to see that it IS impressive that they're doing it with TBI and making those numbers. That was my whole point.

 

How the hell do you expect more? Seriously, how. It's 4 TBI injectors ontop of a blown 502. Maybe you're thinking is all wack but in terms of fuel flow ask holley what kind of hp they can support with a 4 barrel TBI setup. http://www.holley.com/HiOctn/ProdLin...B/950-21S.html take a look at the hp supported and that's with 4 85pph injectors, bigger than the GM BBC injectors. It's a solid system which if it's making that much power could make more if they ran dual 4 barrel TBI setups instead of the small 2 barrel setups.

 

I don't understand why you're so mad.

It seems to me that you're the only one that's blaming the TBI for the lack of power.

BUT, if you want my opinion on the induction system, then I think you're right. Putting 2 stock TBI units on the 502 was a dumb idea.

 

but three mabeee...

 

The big bad blown 502 speaks for itself, cranking out 600 HP

According to the site this 502 has 600 Hp....

Bet he would pick up some more HP by dumping that junk filter. BW

 

I have to agree here a blown BB with only 600hp. This one here I helped a friend build up is a 350 SBC with a 671 making well over 600hp. That 502 is not impressive at all. Sorry but facts are facts I guess. This car runs low 10's on a bad day.

 

yeah its hard not to get caught up in the numbers, the torque he is putting out is probably the worthy measure and why the car is quick.

 

600 constant all the time... just imagine the forces induced onto the crank from the prop alone.... if you look into aircraft engines you would know where im coming from

 

Yeah kinda! It now has 675hp and 510 ftlbs . That does help for sure. the torque was at around 4500 rpm too if I remember right, so yeah. Still very impressive out of a power glide. The car has a 10 point cage a full 4 link tubbed suspension, and all the original interior stuff other then the rear seats. Everything works heater, wipers, radio etc. It's street legal too.

 

Apparently the hot ticket for roots blowers now is a Small roots (142 / 177) and a simple TBI setup like Holley's Commander 950 with 855 PPH injectors.

I wasnt the first to try it out, and i guess im not the last. already I've seen and heard from over 6 people in the last month that went this route. Im even building a 383 Motor, with a weiand 142, and using my commander 950 setup on that.

That 383 alone, with a simple XE270 Hyd.R Cam should be good for over 550-600 horses. It wont be going into a boat, though.
