Well, seeing as how Jeremy made 990 rwhp with a 355 LT1 and a T76GTS with a little 218/218 cam, I think the 220 cam is capable of 600 rwhp.

 

What rpm did Jeremy's peak at?

 

the 220/232? even with the small amount of lift?

If that cam would work, I was looking at the CC305 and it seems like it would work better. Its a 220/230 but with alot more lift. .544/.544(with 1.6 rockers)and its on a 114LSA...would I be better off with that cam?

 

That's what's in my turbo'd 355 (T-76 Q trim)... no numbers yet though.

 

pfff...hurry up slow poke.

 

If work wasn't killing me, I'd probably be done... They need to stop sending me all over the globe. 37,000 frequent flyer miles over the last 3 months...

The engine goes in the car the week after xmas, so I should be ready to fire it up sometime right after the new year.

I finally went to pick up the pipes from being coated yesterday morning. I haven't taken any pics after coating yet...

anyway, back to the topic at hand... I think the CC305 will be a good choice for a street turbo setup. I'll hopefully have some numbers for ya in a month or so.

 

My wife would divorce me if I traveled that much I picked up a tig welder...should be here by first week of January. SHould be able to put down cleaner welds now.

 

All these cam's you are talking about are in the same range. We've been from 221/221, to 220/232, then 220/230. They are all close to the same duration. I pointed out some very high hp examples using 218/218, 226/226, and my very own 224/236. I bet all of these cams are within 30 hp of each other, with the 218/218 being the weakest and the 226/226 being the strongest.

I want to see some more dyno tests on turbo motors with cams in the 230's, 240's, or even 250's.

yeah ill prolly end up going with a cc305, its got a little more lift than the custom one I was looking at..and its still on a 114LSA

 

With my 355 PT76GTS with a 218/224@.503" (0.533" with 1.6 rockers) on a 114 at 14psi the HP peaked and was basically a flat line between 5200 and 5800. The torque peaked at 4800 rpm at 660 ft-lbs. This is through patiot 1-5/8" block huggers, 2-1/4" crossover and 3" downpipe. Probably a little restrictive.
We did a couple of runs at 24psi but, we couldn't get the car to hook on the dyno. I am going to try a 224/224 with a little more lift this time around(mainly for the extra lift). I think a cam any were in that range will be fine for a street car.

 

Or, you could get a custom grind from Comp that would be 224/230-114 and the intake lift would be .605" with 1.6 rockers, if you're that worried about lift. I'm using that intake lobe also. BTW, Cam Motion looked at that Comp 3192 lobe and said that it's impossible and doesn't really exist.

Well, I can get the CC305 new for 200 whereas a custom cam is 300+shipping..and that extra 100$ can go towards something else instead of 3 or 4 hp. =) Plus im not looking for HUGE power, im looking to make what i got last. =) Im sure it will be just fine going from my H/C car to this. Plus I can feel better shifting by 6,000rpms now. lol
