Title: vnt on gas? Post by: _nameless on August 19, 2014, 07:19:38 AM I acquired a 2260vk for free, friend of mine upgraded to a 2566vk on his alh. im working on a 2l / 20v turbo in my spare time... its a AZG block h beam rods and forged pistons, factory crank. Head is from a AWM. So my question is If i use this turbo on gas engine will it fail from heat?
Ive looked around for the last few weeks and have found conflicting answers. My fear is vanes will fail from heat. Thanks, Marty Title: Re: vnt on gas?

The new Porsches are vnt turbos and they had to be pretty heavily modified to get them to work, there is no doubt though that vnt is definitely a better and more efficient turbo. Also need to consider that the TDI/vnt work on vacuum rather than boost to control the boost, that would need to rectified. Title: Re: vnt on gas?

Egt on my stock 3.0tdi can go as high as 1300f. Even just cruising on the freeway it can sit at 8-900f with just a moderate incline and a touch of throttle. So at least some of them have been engineered for the higher temps.The new Porsches are vnt turbos and they had to be pretty heavily modified to get them to work, there is no doubt though that vnt is definitely a better and more efficient turbo.
