^^Mike, understood. All good points and issues I had not considered. You are so correct about shootouts being a PITA. Looking forward to the results of the header you are having made. Thanks again.

Care to share any hints on which route you are going with the headers or will you wait to unveil the choice once the article is done?

AFAIK sikky is the only one who has been doing any production, the other two that I know of are still in the test phases and haven't been finalized.

I will wait until the headers are tested.

My car is pretty much stock. All I have is the K&N intake. I live in South Florida where it is almost always super hot and humid (not a good mix for putting up high Dyno numbers). Around this time last year we had a week or two where the temps where down to 40. I took advantage of one of these days and took my car to get Dyno'd in Miami. I ran all three run's in 6th gear on a Dyno Jet SAE corrected. I put out 399whp and 355 tq. Of course like many other's I was skeptical of these numbers and pretty much still am. Especially when there was all that "chatter" about the K&N actually losing HP. Glad to see an independent group show such promising results. Makes me hope that maybe those numbers were not all that off

Sorry to bring this thread back but its hard finding proven results on this forum or just for this car.
This guy JUST with the K&N made 399whp??? WOw thats crazy! Crazy good?

why is he skeptical of the numbers he put down, in front of his own eyes, on the dyno?

Because its hard to believe that just an intake will give u 20-40 hp at the wheel. Correct me if I'm wrong, I believe the F puts around 350 - 365 WHP?

familycar

I understand that, but if it's proved by the dyno in front of my own eyes, I'd be inclined to believe it :/

Nice exhaust. Definately something to consider.

(unless I missed something by not reading back far enough)... The problem is that there is no baseline for that 399 whp figure. Dynos can vary significantly. One should be skeptical...it is possible that the car would have dyno'd 393 whp on that same dyno with a stock intake...but we will never know, especially since we cannot duplicate the exact conditions when it dyno'd 399.

I heard from a tuner that amongst all makes, they see more factory beasts from the southeast through Texas. Maybe the car is an anomaly.

Bump, really looking forward to your test for a set of headers...

After looking at your project cars I'm trying to choose between supercharging the Tundra or more extensive mods on the ISF.

Such a great write up!

He dynoed in a state that is at sea level on a day that was 40 degrees out......maybe that had something to do with his good results.
