I see the max speending conrod's. but i do know this is good.

\/\/

How much power are you aiming for?

i think make turbo,in between 10 and 15 PSI. 200hp +-

You won't need those con rods for the power you're looking for.
Remember, stock GTi rods (and crank) are forged.
I'm using stock GTi rods at 18psi. Should be making around 205hp.
As long as it doesn't detonate, you'll be fine. I'm also using water / meth injection to help with that. Btw, I do have those max speeding rods. But I haven't used them yet. Maybe they're good for 275+hp.

realy good. i have a question.

my crankshaft is 0,25 mm whith ACL bearings.
i can put turbo?

i buy a maxspending conrod's, but i see this no have the jet cooler hole.
it's a problem?

Anybody have any follow up experience with these? I'm hearing a lot of good things, most of the negative comments are those who are assuming they are junk.

There is a clearance issue I have read with the beefier studs/bolts that go with. I don't think it was that big of a deal though.

Currently running spool forged rods which are very similar to the max speeding ones... the only clearance issue is the main cap girdle hits rod bolt head... a slight bend/ tweak of girdle fixes it very easily. I can't speak for the max speeding rods but I love my spool rods.... well made and very tough.

Still have mine yet to be used. Hopefully this year.

But I have doubts; The rods are heavy which will influence performance. If I use these rods I'll use bigger low compression pistons which will also influence performance. To compensate for this I assume I'll have to use a bigger turbo than the td04-13t, which will also affect drivebility.

I've yet to find a bigger turbo but with quick spool up for my application.

You mean the 2 brace on the main caps that only comes in the mk2 engines?

These rods are lighter than stock rods. You're not going to need a different turbo simply because you're using different rods. I'm using a Td04-13t and love it.

I ordered these rods and am going to give them a try.

Yes that's what I mean.

I bought a set of these, but am hesitant to use them. They do not have the oil spray hole drilled into the top of the main bearing section. I've heard this jet is for dissipating heat from the piston and not necessary with a quality piston. I'm worried about the increased oil pressure on the main bearings though.

Can a good machineshop drill that hole? Is it a possibility? I'm willing to drill mine.
I just took mine out last weekend, I'm going to weight one. To me it's heavier than a stock rod.

They are lighter than factory rods and I am sure that a valid machine shop could drill those holes to match the stock rods. I have ran rods like these without that hole with no issues of high oil pressure.....these engines don't seem to have the high press issue its more like a low press issue most of the time.....

Allright. Got it.
Yup, the oil pressure gauge indeed gives a pretty low reading at operating temperature.

I ended up having the machine shop drill the holes to match stock rods. As noted before with these rods, there is a clearance issue with the rod cap bolts and the main cap girdle rail. I had to file the girdle a bit to get the bolts to clear.

Not yet.. getting very close. Still a few wiring bits that need buttoned up. Here a few pics including the grinding on the girdle I was talking about.







Im going do a full write up on the setup once it's back on the road.

Any update on this engine? And oil pressure readings?

I'm only NA so these rods are massive overkill in my engine.
They are not heavier than a stock rod. Stock rod....423 grams. Stock rod with arp bolts....437 grams. Maxpeeding rod 417 grams.
Why did I put them in? I'm just daft that's all. Bought them before asking anyone.
To be honest I balanced my engine and to do the gti rods plus replace the little end bush and hone...check roundness etc was going to be half the cost of these rods...so I had em...I put em in.

The longer heads on the bolts definitely hit the girdle. I have a friend that just got rid of the girdle and used proper washers. Said he could not see the actual use of the girdle....he is turbo....engine runs well. I didn't have washers handy so I filed the girdle down in four places to give clearance.

My bore is now 75mm. I can tell you the rods go close to the bottom of the cylinders....hard to measure but they do not hit. I had the shells measured in the rods....I can tell you they are round....the little end bushes are perfectly sized....the arp 2000 bolts are nice....the caps lock in tightly on the dowels and the rods balanced to within .5 gram from the factory.

The holes....my understanding is.....not needed....a lot of newer cars are coming out without those holes. Yes....it may help to cool the piston crown.....but I emailed maxpeeding and they do not believe the holes are necessary....others have run them without the holes and found no ill effects. So boom....in they went without the holes and...good pressure for those big end bearings as well!

If we miss a change and rev #$&@ out of the engine at least these bridge girders won't let go.

I like them....Chinese made...yes....but most of what we have around home is too....it's all down to quality control and they seem to take that seriously. Hope any of that helps
