thanx for all the input. all of it, warnings and all.

question tho... since the early torque is what plagues the rods with A28s, how safe are the A30s on stock rods, seeing as how theres a later torque curve?

some of the discussion has actually made me reconsider what i wanna do with this car. if i end up wanting/having to do rods, i may actually make a jump in turbos. thanx for everyones input

 

It seems to me that once you add meth to the equation with any of these turbos over stock K24's,,,this Rod/head gasket issue is a consideration to be looked into.....

 

I would not let a few anecdotal stories spoil your opinion of a fantastic turbo. There are far too many variables that can contribute to bend rods to assume the turbo makes too much torque for the rods. There are hundreds of these setups running just fine all over the world. I have run these in a high timing high boost setup for three years (stock block) as a DD at the TX Mile with no issues. You can find bent rods out there for all turbo setups.

 

How can you say that???Meth allows for more boost safely ,thus more power!!As you know this because you use it to make more power,dont you??.....

 

Different gears make the load different,thus boost comes on differently in different gears....It did with your past tune on my car.......

 

hilarioushilarious specially you Chris that builded a mounster:eek:

 

..I also said when I had my original X-50 that the flash and exhaust was going to be it....lol....But I guess alot of us are never satisfied even though we try to fool ourselves into thinking that......

 

OK,,,,, Then when you are in 2nd gear and floor it at 3,000RPM the boost goes to 1.2 bars...But then when you are in 4th gear and do the exact same the boost goes to 1.4 bars...So,know matter if the dash isnt accurate for exact boost,its still .2 higher..Yes,there is probably rounding in there as you have explained.
Are you saying that that is not that much of a load difference on the motor with .2 extra bars because I would think that the extra .2 would also make more power,thus harder shock on the engine at the lower rpms??
In most cases thats what I have seen a .2 bar difference with tunes and 1 bar wastegates with those same type of test examples....Just trying to understand here....

 

And if you has data logged you would see that in 2nd, you would have been in the 1.3 range but the dash is too slow to pick it up. The dash also round .066 meaning if you are 1.234, it will show 1.3. The dash is basically worthless beyond making sure you are making 1.2+ and not .9.

 

Yes May be BUT...My car has been data logged alot on the dyno several times >>>And in 2nd gear it showed the that time 1.23 and right after that in 4th 1.37...I guess that showed me that there is a difference in gear and load??

 

That was my point at the beggining when you said about stepping the boost up slightly as the RPMs raise.......

 

so what is a good gauge? are most using digital or analog(?) type gauges?

 

When tuning, it's easier to control TQ with timing, than it is with boost...and the factory boost guage is WAY too slow to be accurate for anything.

 

thats what im starting to understand. i will have to start datalogging for accurate boost numbers. thanx

 

Why dont tuners post their achievments with all the bolt ons and give me a good idea who to have tune mine. If torque is limited down low what is to stop this being an 800bhp car
