Carrillo or Crower ?
- Thread starter sledheadd
- Start date
This is just my 2 cents for what it is worth. I have built Nytros and have lots of buddies with them. Almost everyone I know runs the Carillo rods. The Crower rods have less material to them which is good and bad. Rods are the one area I would not skimp though. Lose a rod and you'll have a $3000 repair bill minimum. There is something to be said for tried and tested and that's what Carillos are. Again, I think the Crowers are a great product I just would not trust something I have not heard research or real world info on. I know Crower says their rods are easy on the crank because they are lighter but pushing 300 hp I don't want lighter. If your worried about the weight change out your stock pistons to JE low comp pistons. That will save you some weight and will not have near the potential for massive damage to the motor if something were to happen. Go with the Carillo/JE combo, get your head port and polished and some good cam timing and you will not be more happy about the decision.
not a yammy guy, but we have run both carrilo and crower rods in big race motors(1300-2100 hp big block chevys)..I too would take the carrillo rods over the crowers..(the crowers are nice rods..but not as nice as carrillos....)...never skimp on the bottom end..when it goes boom..it cost big money to fix....the better the bottom of a motor...the better the top performs as well.....if you change rods and pistons make sure someone good rebalances the bottom end.....
Both are good rods. The main reason I would go with the Carrillo's is their car rod bolts. I think the Crower uses the arp 2000 rod bolts which I have seen snap on a few 900 whp rice rockets. Kind of a moot point I guess as we won't ever be pushing that kind of horse power.

rods
I only use crower rods i built an apex last year for a customer who wanted to run as much boost(20-23psi) as his fuel system could stand that engine ran great so from what i have seen so far is crower rods can stand all of the boost that you can give them . Also i was looking to have some custom rods made for my sled so i called crower and left a message for someone to give me a call .One night around 900pm Mr. Crower called me back himself . we talked about what i was thinking of doing and he took the time to explaned why it was not a good idea to do what i was thinking of . The people i do motor work for it seems that money is not a problem for them so i could buy carillo or crowers and i always go with crowers . with all that b.s. i just said can anyone post a pic of crower rod that came out of a sled that failed do to boost not lack of oil any rod will fail if you stand that sled on its tail for to long . i have never heard of one myself but that is not saying much i have heard of one carrillo failing but they could not pinpoint why the rod failed but they did tell me they went back to crower rods only . Please dont think that iam bashing carillo rods they make a good rod but for me i will stick with crower

If you run that kind of boost your askin for trouble on the Nytro. You better put head studs in her and the aftermarket head gasket as well with extra crush to it for a better seal. To run 20 lbs or higher you would be running straight 110 at a minimum. Run 90% 91 octane and 10% 110 and DONT boost over 17 lbs and it will feel like 20 on straight race but you won't have engine damage potential like at 20-22 lbs. All the climbin you see in the videos happens on 15-19lbs on the Nytro, you just don't need more than that. Get her breathin good with a port and polish and seal up those valves tight during combustion for the max time period and you will have a fire breathin beast at 17-18lbs.
I have been running 17 lbs at 5500ft elevation and up on av gas for two seasons now on stock components. I agree the 20 plus lbs of boost days are few but its would be nice to have when needed.
Of course new studs will be going in I'm not gonna cheap out any where it will be done right.
I think the nytro on 22 lbs would be a blast to ride.

If your only planning on turning it up to 22lbs once in awhile, rods and pistons are not needed. Use a head shim and some arp head studs and you'll be fine with good fuel. I ran my sled at 19lbs all season with many runs up at 24lbs (all on 100 octane) and everything looks cherry inside.

boost level
Motleyone hit the nail on the head . The nytro uses the power it makes very well at 18 psi of boost you are going so damm fast up the hill its hard to keep up with the sled . The nytro doest like prolonged periods of time at high boost and sure you will find people that has ran upper levels of boost (16-19) will no problems on somewhat stock engines I dont feel that iam that lucky . For 1600-1800 you can buy all of the parts needed rods,piston,bearings ,head studs ,and gaskets to make it a strong engine for high boost days on the hill
