TRD Intake Questions

2nd gen trd air intake with a TRD supercharger.
No lean out at all, AFR just under 11. Supercharger noise is quite loud. Not sure about much in the way of performance gains, I got the intake before the supercharger.

Don't believe the hype about how terrible it is. I've had no issues whatsoever. It is an oiled filter and my MAF is fine.

 

The new trd is based off of wrong demensions isnt it?

 

Oddly as this will sound, Gadget doesn't run a boost gauge. Said he believes that his s/c was at ~8psi on the dyno.

My engine which I am prepping to install in the next two weeks, is very similarly built as his. Minus the stroker crank.

With URD's configuration on that dyno, take notice of how high the torque is at 2250 rpms. Over 300. As well that it was a fairly linear progression. Very impressive.

To compare to a turbo 1GR, in stock trim, it makes roughly the same torque at the same ~8psi. While right at 400 peak whp. Again, stock internals.

Different volumes of flow between turbos and centrifical superchargers.

On a stock 1GR, I highly recommend against surpassing 450 wtq. Which roughly equates to 400 whp depending on the s/c variant.

With my built engine, Goldylocks, I do not know exactly what to expect as far as output will be concerned, since it has been over-bored so much. ~8 psi will be the starting boost level as for reference to the many dyno charts which I have catagorized. Then up to ~15 psi.

On my last built engine, with the only change aside from being built, was that the compression was 9.5:1, the engine made what is in my Sig. I expect this 4.xx liter 1GR to output more.

With the stroker engine, which also has cams, I expect to make something similar to what Gadget's truck did at ~8psi, but with much more torque.

So there are the tasty performance treats which I can offer.

A 1GR with rods, pistons, head gaskets, and head studs, is capable of 600+. It has been done and proven. Just need the F/I inducer to get it there.

 

For all of the "blown built engines," which have happened on the two forums which I am a member of, I can tell you that poor tuning, owner error, or a combination was the root cause. Me included.

 

From what I understand, you are like a death sentence for tacoma engines.

 

Just doing a better job of testing the "extremes" than Toyota.
