rob wild Posted October 28, 2008 Share Posted October 28, 2008 Hi Guys Just wondering if anyone has ever used a SCAT rod? Just been talking to a mate of mine that builds V8 engines up and recommend the SCAT rods as been good as they are balanced within -+1gram and a strong H beam construction. They are also forged from high Tensile 4340 Steel and come with ARP 2000 Cap Screw. Just wondering if anyone had a HP rating and a weight for them? Just found a place over here that sells them for £298 which seems excellent value and better quality than Eagle. All opinions welcome Quote Link to comment Share on other sites More sharing options...
rob wild Posted October 28, 2008 Author Share Posted October 28, 2008 Just found out the weights from an email they just sent me back, 546g. Seems very light! Just interested in the HP rating now Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 28, 2008 Share Posted October 28, 2008 I *THINK* you'll find Scat and Eagle are both made in the same factory. If you want to be safe Carillo, Farndon, and Arrow Precision are the main players who make decent custom rods. Saving a few hundred quid on rods always sounds very dodgy to me, they are one of the highest stressed components in the engine. Quote Link to comment Share on other sites More sharing options...
rob wild Posted October 28, 2008 Author Share Posted October 28, 2008 Ahh right didn't realize that! Its not a money thing really, just I was thinking about the rotating mass of a set of heavy rods. I'll stick to the original plan of BC or Carrillo thanks for the advice Chris Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 28, 2008 Share Posted October 28, 2008 Carrillo have bought out a budget rod and crank manufacturer called K1. I am told that the K1 rods are not bad. Some sell them as Carrillo K1, but K1 is still an independent operator making different products to the mainline Carrillo rods, in a different facility. The owner of K1 has made it clear that Carrillo rods and K1 rods are not directly linked. If I were after risking a cheap rod I might be tempted to think Carrillo wouldn't buy a firm that turns out junk. Quote Link to comment Share on other sites More sharing options...

That explains something I saw some K1/Carillo rods on ebay and thought they were much cheaper. What do you think of Brian Crower Pro Series Rods Chris?

paul mac Posted October 28, 2008 Share Posted October 28, 2008 Just found out the weights from an email they just sent me back, 546g. Seems very light! Just interested in the HP rating now i'll weigh my eagle rods tommorow Rob to see if they are indeed the same, i did extensive searching on the Eagle rods and could not find a single failure of the rods themselves, the only evidence being a failed rod bolt, eagle upped the size of the bolts and now fit ARP as standard, the yanks run some big power with them, imo everything indicates they are more than up to the job of around the 600 hp mark, if i were planning on 700+ hp i would defo have gone carillo but at my power level i think they are total overkill Quote Link to comment Share on other sites More sharing options...

Wow never realize that either I was going to only buy from Dusty or Kyle and buy the following ones: Brian Crower Pro Series Rods for 1993-98 Supra Part # BC BC6309 i'll weigh my eagle rods tommorow Rob to see if they are indeed the same, i did extensive searching on the Eagle rods and could not find a single failure of the rods themselves, the only evidence being a failed rod bolt, eagle upped the size of the bolts and now fit ARP as standard, the yanks run some big power with them, imo everything indicates they are more than up to the job of around the 600 hp mark, if i were planning on 700+ hp i would defo have gone carillo but at my power level i think they are total overkill That would be great if you could Paul. Again its not an attack of the wallet its more I want a light rod to help with the lag etc. I don't think I'm ever going to want anymore than 600rwhp but also I want the engine to be reliable.

Guest yiros Posted October 30, 2008 Share Posted October 30, 2008 Photo of a Scat rod vs OEM Drag guys here in Oz with their 2JZ powered cars are making over 1000hp (crank) using Scat rods and JE pistons. Rod and piston combination below. These are from my build up. 3 of the rods balanced weighed a 0.1g more than the other 3. These are now balanced...

StuartW Posted November 1, 2008 Share Posted November 1, 2008 Hi, I Was just about to buy Carillo and JE or CP Pistons. I am now tempted to go for these scat rods! Any pointers as to who supplies them? Also Wiseco pistons are the only Teflon coated piston available for the 2JZ so surely they would be preferable, especially as they seem to be priced the same?

rob wild Posted November 1, 2008 Author Share Posted November 1, 2008 (edited) Hi, I Was just about to buy Carillo and JE or CP Pistons. I am now tempted to go for these scat rods! Any pointers as to who supplies them? Also Wiseco pistons are the only Teflon coated piston available for the 2JZ so surely they would be preferable, especially as they seem to be priced the same? You can buy them from the following: http://www.flatlander-ipp.co.uk/rods-toyota.shtml I spoke to the guy that runs Flatlander and he said that he has never had any problems / returns with any of the rods be it Carrillo(high) Pauter/oliver racing(mid to high) or eagle/scat(budget). Although he did say that it all comes down to budget and that he would advise to go for the best you can afford which would be Carrillo. Seemed a nice guy and very knowledgeable He did say that he had seen a eagle rod snapped but it was a cheap bearing that had over heated and seized. On another note your right with the Wiseco pistons and thats what made me choose them for my build I went for the 87mm as I have had to bore the block due to scratches.

StuartW Posted November 2, 2008 Share Posted November 2, 2008 Why pay tripple when these are proven? I have found in Marine parts a lot of manufacturers just brand components and tripple the price, Exactly the same parts from the same factory! "Drag guys here in Oz with their 2JZ powered cars are making over 1000hp (crank) using Scat rods and JE pistons." What we really need is some proof of manufacture. Although a proven product is even better. Q To Yiros. Can you list the part numbers so we can check they are the same spec as the ones for sale here in the uk? Also has anybody got a contact for wiseco at competative prices? Thanks all. Quote Link to comment Share on other sites More sharing options...

Flatlander does wiseco pistons as well: http://www.flatlander-ipp.co.uk/pistons-toyota.shtml As far as the rods I would love to see some dyno print outs and specs of the bearing/pistons used in a "1000bhp" drag It would be interesting to find out were Carrillo, scat and eagle rods are made and if it is the same Chinese factory Quote Link to comment Share on other sites More sharing options...

Dyno print outs are irrelevant. Rods aren't going to make any difference to the power produced by an engine. As for "proven", just because people are using something doiesn't mean it's proven. You could say that stock rods are proven, after all people have run large power using them. And just about every other type of rod. How long they will last is another question! It would have to be a real piece of crap to fail within the first few tens of thousands of miles. All you can do is look at the specs and the quality of the finished forgings.

Sorry Simon I didn't mean to be critical of Carrillo! Please dont take it the wrong way. All I meant is that since they have been taken over by Pankl (may 2008) their has been a few Q&A issues with some rods being out of balance (which is very unlike Carrillo). I just wonder if they are being forged in China along with eagle, Scat, K1(which is part of the same group) and being finished in the USA? And Pankl are now using Carrillo as a R&D facility which is what they said in the press release. Part of me just wants to say sod it and buy a set of Carrillos or BC rods. But then I keep coming back to many people who have used cheaper rods with no problems! What I meant by "proven" and "dyno prints" is i would like to see a few different things like how has it affected the power band, lag and if the lower rotating mass has helped with the rev limit. Also you're right and thats what I also meant by "proven" how long will they last, however Michel has had loads of builds using eagle rods including Jays car. Which has now done 1000's of miles and some seriously hard drag racing I.E. TOTB where their was quite a few engines letting go. Again this is just purely a technical exercise for me and more importantly a hobby! Quote Link to comment Share on other sites More sharing options...
SimonB Posted November 2, 2008 Share Posted November 2, 2008 That's cool Rob, I didn't read it as being critical. I don't know about the others but I'm pretty sure Carrillo still make their own forgings at their base in the US - that's what their website still states and I can't see them changing. TBH I expect all of these rods would be fine. You don't exactly hear of people breaking the stock ones, never mind any forged aftermarket ones. I also have no doubt the Carrillos are better quality, you just need to hold one in your hand, they are lovely. But it probably makes no difference in reality. I very much doubt you'd see any difference in power band etc. The benefit of lower mass rods is more the reduction in load where the piston changes direction so reliability basically. I don't think anyone would set their rev limits so close to the edge as to show up any difference. There are so many variables with specs you're never going to be able to compare just something like rods anyway. Quote Link to comment Share on other sites More sharing options...
