NZ951

Please explain in detail how and when and why Lindsey Racing ripped you off. Then I will
get with Dave and get the complete, documented and real story. I already know most of it,
but will be happy to share the real truth with everybody. I'm getting a little tired of reading your slams when none are truthful at all.

It's time the real ZN951 shows his true colors.

Hey stewardx,
Who the hell are you btw. You seem to know everything about
Lindsey's unhappy customers. If you're Mike or Dave, please be
man enough to step out & not hide under some other names.
If you aren't either of them , please stick your nose elsewhere.
If you're tired of reading the slamings of vendors, look away &
it'll not bother you any more. People are entitle to voice their
opinions. Like it or not this is life besides those of us spend
hard earn cash on purchases & will not make false claims
unless the after sales services or products delivered are
questionable.

Unless you are running a 3liter or 2.8 liter#10 hot side is to big .

Also what kind of turbo are you using with #10 hot side?

More lag for sure.

The #8 vs. #10 is a good topic let's hear experiences.. Could we please keep this topic alive and not turn it into a vendor issue??

Russ Murphy

Is anyone running a #10 turbine on their 2.5 liter? I know mumzer got a #10 on a Lindsey turbo as well, however it is going on a 16v 3.0 liter.

Hi Fast951,
Sorry, I just can't stand it everytime when I see poster child
of so & so vendors running out to defend them. To them, it
seems like their vendor can't or will never make mistakes.

Yes but to be fair there is a big difference between a vendor making a mistake and allegedly ripping someone off. Clearly it is not the point of this thread to be dragging this out now is it. So why not get with the thread topic!!!

I would have thought that you could easily get an 8” to produce 400rwhp on a 2.5 possibly a bit more on a 2.8 or bigger. Exactly how much hp do people need, even in a track car, unless you are racing for money. The reality is 350whp is more than enough for a road car, that might see some track time. Especially in a car the weighs under 1400kgs!!!

I assume you are looking at 500+hp with a 10” turbo

J Chen

That's what I'm hoping to achieve with my GT25TO4S.

David Floyd

It's not always about max hp, if you can run moderate boost level and produce a wide usable torque curve verses high boost and "peaky" power like turning a switch on and off, which is more driver friendly ?

A #10 turbine housing may not be correct choice for a 2.5, but does well with my 2.8.

It is wise to have someone with the know how to put one in the correct size turbo, TO4 B/E? A/R 50/60? #6/#8/#10 ? wheel sizes ? GT25/35 ? too many choices for the average dude to pick the correct unit IMHO

Duke

Yeah some real world experiences would be good.
I actually cannot remember seeing one post on this forum from one that actually have tried a 10# hotside on a 2.5 liter engine.
Well, perhaps some of the tuner's turbos have bigger hotsides but that's in the dark..

Duke

You can't a 8# to produce 400rwhp "easily"...
That will need very high boost.
Since the bad effects of a bigger hotside is 99,9% of everything that gets mentioned I won't go into that.
But one of the benefits are that you need less boost to get the same peak power.
Which in turn usually means cooler air, which in turn means... etc.etc.

Let's just stay objective about this and not disregard it as "no, it's waaaay to big" without even thinking about the effects.

J Chen

Less boost to get the same peak power.
That will also depends on the compressor trim
that's being used.

J Chen, I sent you couple of emails, did you receive them?

Let's narrow down the variables we are dealing with, and for now let's assume the compressor side is the same between a #8 and a #10.

We have few variables that we have to be concerned about:

1- lag (#10, will increase lag over #10)
2- Flow (#10 flows more than #8, so there will be less back pressure, allows you to run more boost, and you can make more HP). [Back pressure is also a function of the turbine wheel]. Backpressure affects performance as it induces knock, and indirectly this will affect timing...
3- HP (#10 will support more HP than #8).

There is no free lunches here.. More HP by using the #10, more lag, narrower power band. It's a balancing act.

J Chen

Hi Fast,
Emails ? Where ?
