Yes. You raised an excellent point.
You will not
get the same absolute numbers that I have...
...however, you will experience the difference
between those two dyno runs, because the only
change between them was just the spacer alone
And I don't have a CAI...
I am the only one here who runs the dreaded and feared power robbing "warm air intake" that draws air from inside
the engine compartment. (gasp!
) Which, according to the overwhelming consensus of opinion here, creates a loss
of power and not
In contrast to the majority, I hold the opinion that the gains of cold air intakes are highly overrated and feel that my Injen intake is good for at least a few ponies.
Now, I do
have an LCE header, and it accounted for dropping the torque peak from 3,800 rpm down to 3,150 rpm. I know this because the Toyota factory dynoed their bone stock 2.7 and got a peak of 3,800 rpm, and I dynoed my 2.7 with the header and got a peak of 3,150 rpm.
The actual numbers could be very minimal, if not seen at all, without these other upgrades. This could very well be something that has absolutely no effect on a stock motor.
Lengthening the intake manifold runners on any
engine, stock or not, will definitely
drop the torque curve lower in the rpm range, because that effect is based upon fixed physical laws.
So whatever your stock engine's peak torque was before won't increase
... because on my engine, with an intake and header, the torque peak didn't increase either. It's worth repeating that my torque peak was only moved lower
in the rpm range, and it was also fattened up a bit, but the absolute peak did not increase
Or it could yield the same numbers. No one will really know until it is tested on a bone stock motor. I would feel perfectly comfortable buying this product and running it because I also have a CAI and a LCE header but on the flip side I would be sceptical of purchasing this for a stock motor because there is no data to go off of.
I'm glad you raised this issue. Everyone needs to look closely at that comparative before and after dyno chart.
The peak torque is not increased
... just moved down lower
in the rpm range.
