So as a lot of u know, I’ve had my ‘16 f-type r dynoed on a Dyno Dynamics. I try not to get too caught up in numbers since dynoes are a tuning tool more than anything else. However, needless to say, I just wasn’t impressed with those numbers. I guess they don’t call Dynamics the “heartbreaker” dyno for nothing. Hahaha. Anyway, I did another dyno run, this time on a DynaPack at Road Race Engineering in Santa Fe Springs, California. So on this dyno, which reads high like a DynoJet, my R put down 523 whp/512 ft lbs tq. Factoring in the 20% drivetrain loss, that puts me at 655 hp/640 ft lbs tq!! Pretty impressive. Now I do have to say, there is one difference between now and when I dynoed on a DynoDynamics. I took out the 200 cell catalysts and replaced them with a cat-delete straight-pipe. Not sure if that translates to any actual gains. But I can tell u this, my “butt-dyno” tells me there’s a significant difference, particularly in the higher rpm range. Again, not sure if numbers-wise there is any significant difference. Just sharing my personal experience. The drawback? The car sounds like **** now. Like really really bad. Sounds cheap. On top of that, if u live out in California like me, it’s an ultra expensive ticket if you’re caught running a straight pipe on the street. So if u can’t afford the ticket, I definitely wouldn’t recommend it. And that sound? Absolutely horrendous. I’m gonna take it to Fontana Speedway next month for some 1/4 mile time slips. After that, I’m putting the 200 cell cats back on.

 

Info missing here. What were your Dyno Dynamics numbers from that first run?

Disregard. Found the original post here in post #26.

I can’t seem to find the chart. But it was 452 whp. Don’t remember what the torque was.

 

There was another run after that post. With all my current mods listed in my signature. 452 whp. Which in theory is about right since DynoDynamics read about 12-16% lower than DynoJet or DynaPack.

 

I guess my real question is... did you get a tune that was able to accommodate the additional airflow? If so, was the result the same 7-10HP?

 

The VAP tune accommodates both 200 cell and straight pipe setups.

 

OK, but my question wasn't related to either of those exhaust components. It was related to the new intake you put on that was advertised to provide as much as 30HP. I thought 7-10 was more likely and that was confirmed when you tested with the other dyno prior to the tune. Others on that thread thought that perhaps you weren't getting more as you had not added the tune at that time. However, separating that component out might not be simple so you may not be able to tell without removing and re-testing (now that you have the tune) but few would have any real justification to do unless they were the mfg of the intake.

 

Looks like u answered your own question. Hahaha. To clarify, the Eventuri Intake was the 1st performance mod I did on my R. There’s no way at this point that I would be able to test that alone. Nowadays, very few cars if any, are that restrictive on the intake end. A 7-10 hp gain is about all u can expect.

 

That sounds pretty normal for Dynapack. Since they bolt right to the hub they are spinning less mass.

We did a lot of work with a Dynapack setup when we were working on Lance's crank pulley tune, long before anyone else had come out with this. Such a pleasure to work with because it rules out tire pressure, strap tightness and all kinds of other inconsistencies. The runs are so consistent and repeatable.
