Have any pics of this one?propably not a vq45 but a vh45??

 

The dyno that I go to in consistent. I do understand that there is sometimes error, but I have never seen any on this dyno. It is dynojet and not a load based dyno.

 

sorry a vk45 ... the engine in the Q45

 

You can easily see up to a 5 hp swing on ANY dyno between runs. This swing is much larger than any gains a bored throttle body will give.

I have ran many cars on dynojets and never got the same exact numbers on each run.

 

agree to disagree

i agree that each dyno run will be different due to variances in testing parameters. if you get back to back runs within 1-2 HP, consider it a lucky coincidence.

best of luck

 

If you saw a 1-2 hp variance, how would determine if a gain was made?

I am interested in seeing the dynos. I had already bored my throttle body and replaced it due to TPS codes. I didn't feel much of any gain before it began giving me issue. I had a bored TB on another car of mine and it gave nice throttle response, more than I felt with the same modfication on the Z.

 

I will just do it, then post the numbers up and you can give me your opinion. I would think that any increase in air you can give this engine would help out. Does anyone know if the q45 throttle body bolts up to our motor? I am sure you would need to make the inlet to the plenum bigger, but this shouldnt be to hard.

 

I believe the Q45 TB was welded to the plenum on that car. So I am guessing that it doesn't bolt up.

 

HUH?????

 

:

He asked how big is the stock throttle body is. I believe its 70mm... not sure though.
