AVO vs Innovative

[diss7]

FWIW I've decided to stick with my decision from 3 months ago and go the AVO way. Just need to confirm with my tuner that he is okay with the ECUTEK system.

Slightly O/T. 5/6 years ago I had a silvia with just shy of 200rwkw. Loved that car on the street, well the power anyway, the suspension was too firm. I said at the time that I didn't see the need for more power than that on the street and I stand by it. It was basically just a stock setup, a boosted S15 turbo, and replaced the fuel pump as stock one was a little irratic at that power. I/E/Cooler/Z32 afm, but stock everything else. Even ecu. Couldn't even tune, had to rely on stock ecu. Too poor at the time for stand alone.

Sort of relevant though, as the 86 would be the same weight as the silvia, if not a fraction lighter.

I'm just looking to replicate that setup. Here's the dyno....

Looking at the graph, it looks peaky, but it really wasn't. Certainly didn't suffer any turbo lag. Drove plenty of mates cars who also had silvias, whose car's had more peak power, but obviously bigger turbos. I would've preferred their cars on the track, but mine was definitely the better street setup.

If the AVO setup gives more low end power, thats a bonus. But, I certainly never felt like the silvia needed more. Also FYI, 255/40/17s couldn't hold this power in 2nd gear. 235/45 semi slicks did though.

Also, the graph says Flywheel HP and torque, as at the time these dynos were generally used for crank measurements. But NZEFI used them at the wheels, which is what this graph is.

Must have been FUN!

I've just quickly converted my dyno to HP and put it and the AVO graph together.

Disclaimer - These two dyno results are literally 5 years apart, and on dynos on the opposite side of the world. I've printed both graphs and just taken markers at 250rpm increments. I'm also about 5 beers down, so take this info fwiw.

The silvia is my old car from 2007. As said above, I thought this was a great street setup, and is what I am looking to get out of a 86.

Reason I'm putting it up, as even silvias (well 240sx's for yanks) with sr20's are common pretty much everywhere. Most of us have been in one. Certainly a lot more common than a boosted 86/BRZ. So, based on that, it should help for those looking for answers as to the "how will it feel" questions.

The silvia is a stock t28 from s15 silvia, on a sr20det. Just standard bolt ons, i/e/fmic. Std ecu. Turbo is boosting 16 psi.

The AVO line is their kit for the 86. Their kit is only running 5/6psi, but Paul has advised that is can run 16-18psi!

We're not looking at peak power here, as the boost pressures are very different. We're looking low end. The AVO line won't change low end with more boost, and as you increase the revs it will only climb. How it will climb I'm not sure.

Low end we can see its marginally better than the sr, although I would recommend considering the possible margin of error of this comparison, and assume that is pretty much the same. Who knows, it might be better.

Until I get the kit, and have it dyno'd in the same condition on the same dyno, this will have to do. I'll be able to overlay it properly too, as they'll still have my graph on their server.

At least for me, this has confirmed I'm making the right choice, as I loved the power delivery of this silvia for the street.

Anyway, enough jibber jabber...

Awesome job, and even better with the . I'll drink to that too! Cheers!

In fact at low boost level, the tvs design is more efficient than the twin screw (<10-12psi).

the only problem i thing the tvs 1320 is a little too big for the fa20 and the 1050 is far from ready afaik. I wouldn't mind a kit based on the lysholm 1200cc tho.

This is correct. TVS are more compact (compared to M series roots type Chargers) as well as efficient. R1320 might seem a little big, but lotus guys with 1.8l 2ZZ are using them without a problem. efficiency under 1800rpm is compromised a little, both on the 2ZZ and probably the FA20 too (a good intercooler and some discretion when under load i.e. don't floor it at 1500rpm shift down instead) but from there it has relatively good thermal characteristics (~70%) compared to a twinscrew (~65%) of equal or even lesser size. having had Both styles on a Cobalt SS (swapped the M62 for a .94L twin screw first then an R1320), i would not hesitate to buy a R1320 kit for this car.
