The Stovebolt Site Forums The Shop Area The HiPo Shop nitious on a 235?!

Just had a quick thought,Has any one put a 235 on nitroius? Just a late night idea! If so,what sort of levels on what sort of mods? If not just laugh it off!! Thank Al

I don't see any reason you couldn't run a 50-75 shot very safely. You might even be able to spray a 100 if you keep your AFR in check and pull a touch of timing. Be pretty torquey off the line for sure.

sounds like you figured out the best use for the nitrous, crack the tank and enjoy the laugh!

You could do it at least once!

now that was funny............dave

there was a guy around here 20 years back that had a turbo on his 235

The 235 is a pretty tough engine as long as you don't over-rev it. I don't see why you couldn't, but I would run fuel injection and electronic ignition with a rev limiter if I was going to do something like that for more than one run.

one thing i've kinda figured out is you can really do alot with these old engines its just how much do you want to spend alot of times it ends up being the cool factor more so then the performance i seen on the internet somewhere that someone put a turbo on an old studebaker flathead six, i think it was a 51 bullet nose stude

You just can't expect to make huge amounts of power with stuff like this, but adding a small turbo or supercharger to overcome the really crummy head flow of a 235 would wake it right up. I just wouldn't go for more than 6 pounds of boost or you can expect to be ripping the studs out of the head and replacing a lot of pistons.

Don't ever expect to beat a well tuned SBC, though, there's a lot more refinement on head design and rod strength on those.

is this a what if or are you really thinking about doing it ???
i;d think a 50hp and a pulse system would hold up

I would like to try it but it will be when I have my new engine is on the stand! Thanks for all the replys guys!I was thinking of 50-75 hp shot,just to give it a little extra. Al

I think you could make a 235 sing if you bought the right parts. If I remember right, the connecting rods have the big end the same as a Chevy small block. The length is pretty long though. But you can get some long rods for a SBC. Might have to buy 2 extra ones though. Well worth it for some nice strong forged rods. Still, the compression height wouldn't be exactly the same. That shouldn't stop you. Order some custom slugs from anyone that makes them forged, and the compression height can be adjusted.

I believe Sanducci even solved the weak main problem. He studded his mains and put an additional strap across the top.

For the head, someone makes an aluminum cross flow head for those. I don't remember who. But if worse comes to worse, you can adapt small block Chevy heads to work too. I've seen that done. You have to cut the last cylinder off each head and weld them together. Isn't that what Sanducci did too?

Then, why can't you run big boost and 5000+ rpm on a 235?
Rule of thumb is, if you can do 2 atmospheres of boost (1 atmosphere to bring it to manifold pressure of zero and 1 atmosphere to get it up to 14.7 psi), then you'll be making approximately 2 hp per cubic inch. That's 470 hp, folks. From a single turbocharger.

It's not going to be the cheapest rebuild option, but it will probably be the trickest.

Speed costs money, how fast can you afford?

My last S&G event with NOs was a dust pan full of parts when we went to a 150 shot on a tired engine.

Turbo or supercharger would add a fair amount, however like 4onthefloor stated, I would add EFI and a rev limiter to keep the pistons in their assigned bores. Nothing ruins a day faster than a parts-scattering event.

Sanducci even solved the weak main problem. He studded his mains and put an additional strap across the top.

That's the Gen-3 L6 (194, 230, 250, 292) engine. The caps are quite different - there's much less room across the top of a stovebolt cap to locate a strap.

There's also a big difference between how nitrous affects an engine and how a blower or turbo does.
Nitrous is very violent, the cylinder pressure goes off the scale instantly. The ratings by "50 hp" have no basis since the power added isn't RPM sensitive - it adds 50 ft. lbs. etc. regardless of engine speed.
Blowers are much kinder, the "spike" in cylinder pressure is lower and lasts longer than even the same power developed by traditional high compression.

I picture this as about the same thing happening!



Geo metro on 100 hp nitrous, very funny.

i only got one answer why!!!!!! do you have a big check book and like seeing broken parts?
