The L430 isn't balanced? Also, is there any info on your is38x offering? Can you also provide some information on the clipped turbine. I've been doing some research on "clipping" and have read a lot of opinions and many for and many against clipping. I'm curious what your take is on it regarding these turbo applications that you offer such as spool, effeciency, how aerodynamic flow is affected etc. Also which offerings have upgraded shafts? I see you mentioned that you can run stock and upgraded shafts with your offerings which have the upgraded shafts or is it a paid upgrade? Thank you.
Oversight, Yes every single turbo, including the L430 is VSR balanced. Wouldn't dream of selling any unit not VSR balanced.
IS38x is a stock turbo with upgraded bearings and the clipped turbine. The clipped turbine, helps with the top end power by reducing back pressures and lowering EGTS. There is a little bit of extra lag, but hardly noticeable.
My opinion? the L430 is ideal for someone with a blown IS38 that wants to ditch the inserted compressor cover, a bit more power but not looking for going the whole hog or buying a whole turbo.
L450, although an entry level complete turbo, really is brutal, it makes power and spool unlike any other turbo on the market due to having a OE profiled mixed flow turbine but larger. It has a big torque area and also capable of holding power to the redline. It's not the highest BHP unit, obviously and never going to set 1/4mile times alight but has a fun factor of 10 simply by its overall performance.
L500, is on par with a lot of other 500bhp units around, we tried to maintain spool by not clipping the turbine wheel and also run a good sized compressor wheel. Whilst we only state 500bhp on these, I do know they are capable of more. When you run a turbo of this size, you have to consider that fuelling and pressures sensor are going to need to be upgraded to get the most out of it and above 500bhp it can get expensive.
L5656. We will keep you updated, It's a new designed wheel, with a proven compressor wheel and hopefully be able to knock out some decent numbers.
The upgraded shafts are on the 2 larger turbine wheels, the 54mm L500 and 56mm L5656 wheel. The L450 wheel is a stock shafted wheel. We have ensured that during our development of the thrust bearing upgrades that the shafts, bearings and bearing housings are all modular, so we can standardise the units and not have to use a different bearing housing for the larger shafted turbos.
Our biggest achievement has definitely been to incorporate a thrust bearing as durable as say the TD06 , which is proven to work well, into the IHI bearing housing in order to maintain the stock appearance and fitment of the turbo. We really took the IHI IS38 back to basics and tried to rebuild the cores up from scratch, taking the best parts of the original and incorporating them with new better parts whilst offering a wide range of turbo's.
