rod question

[m.lion]

360 bmod motor which rod would use? compstar,eagle, scat. tell me why other than price

[TeamGRT12x]

I would use either a Scat I beam or a rebuilt OEM rod. Anything more is overkill.

[stockcar5]

depends on the rules and budget. i'd go with the lightest rod possible if allowed. probe has some 560 gram i beams for just under $400 that i use alot. if price and rules dont allow i'd go with scat pro comp i beams.

[TeamGRT12x]

The pro mod rod is a nice budget rod for say, a motor making 500 horse or more. I'd consider it overkill for a B-mod though.. unless it was a B-Mod on alcohol with aftermarket heads making big power.

[connor]

If you get a light rod make sure you get a light piston or your looking at trouble. Heavy piston light rod = bent rods at high rpms and a pain to balance

[TeamGRT12x]

We're thinking of two different rods then. The Pro Mod rod would be with 7/16 bolts similar to an Oliver in design. The rods that I would run would be the standard off the shelf Scat.

[TeamGRT12x]

The Pro Mod is also called the Pro-Comp rod by Scat. When I was using them, they were called the Pro Mod Rod. My balance sheet from a motor I did in 08 shows the rod total weight was 612 Grams. 2.1" Pin, 6" in length. Scat or Eagle standard I Beam with cap screws or thru bolts. It all depends on your budget and rules.

[stockcar5]

yes the pro comps i was refering to are the scats with the 7/16 capscrews. very nice rod for less than $300, and they weigh almost the same as the cheaper scats. overkill never hurt anybody :) the probes are much lighter as i said. they are also sold under other names like competition products, rpm ect..

[TeamGRT12x]

They have lightened the design since I last used them... Yes that's another option for a rod under $300.

There was a place selling some really light I Beams but can't remember where it was for under $200.

[fast_crew]

K1 technologies has some really nice stuff, fair price and good quality.

[turner]

How about the eagle sir rods. I have used them in 3 engines and had good luck, but they are about 350 hp max. Any opinion ,good or bad about them?

[TeamGRT12x]

Those are an awesome rod Jeff, for the money. Distributed by RPM out of California.

Those are the rods that I am thinking you guys are referring to. The rods you have Jeff would be fine, but I've gotten plenty of use out of the standard Scat stuff that costs around $200.

With the IMCA rule that you can't have cap screw rods, it really limits you. Wish they'd lift that rule, a lot more motors would be legal then from other flat top 9-1 rules.

[TeamGRT12x]

Yeah, those Scats I sent the link too are what I have ran in my A Mod before. I'm going to try the rods you've got in my next piece though.

I just read the rules and they did change them. I didn't keep up on them after I moved up. Cap Screws back in. I like that idea.

[stockcar5]

i wish we could run those l/w rods with the imca 360 engine option. i'd use those in a heartbeat.

[stockcar5]

i talked to tom at imca about a month ago and he said i beams only, and no i beam that has been machined on the face or sides of the beam. must have oem type forging line like the cheaper scats eagles ect. you know how imca is with rules..takes them years to figure out 1 simple thing.

[sj valley dave]

Seen many discussions on the pro/con of H beam vs. I beam and stretching vs. compression forces...Speedtalk Advanced Engine forums and Yellow Bulletforums have had many in depth discussions about this. In the end it came to a draw, that properly designed rods with the correct material will work, weather H or I beam. We run an I beam billet rod and they are going on their 5th season. Just keep magnafluxing them after 1200 laps.

[TeamGRT12x]

That's why I suggested the rod that I did. Must look OEM in IMCA. Those H Beam rod motors won't make it at Nationals.

[TeamGRT12x]

There are plenty of better paying races. That's not the point.

OEM or OEM Replacement Rods, 5.7 or 6" Cap Screw Allowed. I'd say it is pretty clear that an OEM Replacement isn't an H Beam rod.

[TeamGRT12x]

And if a guy wants to put H Beam rods in a flat top motor making less than 450 horsepower more power to him, but it won't pass tech in IMCA. One thing they did that I think is stupid with the rules on crankshaft was dis-allow the Scat 9000 cast deal. Has holes in a few of the rod throws, so it's considered "lightened".

[TeamGRT12x]

I guess what I read from IMCA was wrong then, that the Scat 9000 crankshaft commonly used was illegal due to the crank counterweights. That part number is the cast replacement.

Titanium rods. Nice. We had a set in an open motor in 09. Spendy but nice.

[sj valley dave]

SCD, you got a great price on those rods...Right now a set of Crower Ti rods are right at $3,500 a set after discount and the Trick Ti rods weigh 414 grams each...$3,000 and under 400 grams...smokin deal...Are they Chinese Ti rods or USA? I see there are a lot of Chinese Ti rods starting to hit the market...

[TeamGRT12x]

There are plenty of parts out there that are worked up. Did you see the set of pinto spindles that had had been altered for more camber?

[sj valley dave]

Hey SCD, if your rods are not Ti, sure would like to know what their made of! LOL Don't see many Ti rods that are under 425 grams...LOL Unobtanium maybe???

LOL Unobtanium maybe???
