AVO Turbo Kit Results and Review!
 

This car is @nataku 's Hot Lava FRS!

His baseline pull was with an Airaid intake and Mach V Muffler Delete. It made 152.38 whp and 127.27tq before the turbo kit.

We installed the AVO Ceramic Coated Turbo Kit and AVO Optional Blow Off Valve. We also installed a Perrin Over Pipe and Perrin Catted Front Pipe as well.

We were very happy with the results for just a base map! The car feels strong and is a blast to drive! Can't wait to do another one!

242.76 whp / 208.57 tq !!

Those numbers and curves are delicious. I want...

Can't tune out that dip?

Looks good @nataku !

The base tune is designed for a fully stock exhaust system. My guess is things are a bit uneven because my exhaust is very free flowing.

O I was under the impression the AVO replaced the exhaust manifold which was the main cause of the dip ^_^ guess I was wrong

Mine was the same way. Was very wonky due to one less cat but with more tuning it could smooth out.

Please keep posting #'s in the future. I can never see your graphs at work lol.

You are correct. Sorry I meant that the base tune is designed for the kit + a stock turbo-back (originally header back on a stock vehicle).

I plan to have some live tuning done when I get a permanent catback system I like. I'll be tuning for 93 pump since that's all I ever use anyway.

Are the dyno tuners able to tune the ignition table that effects the famous DI problems?

Who is gonna do it?

Of course it can be tuned out...

Nice! I'd recommend getting the live tune done on your current catback if possible. Even if you plan on changing the catback exhaust I can't imagine the tune requiring much (if any) tweaking when switching from one catback to another.

Haven't decided yet.

I have the stock muffler back on now. Given the massive loss of hp N/A that the muffler might have caused I have reason to believe the stock muffler would have a huge impact on exhaust flow. I'm also noticing a bit more turbo lag in aggressive shifts since I put the stock muffler back on; not really laggy though, just that it takes a half a second or so to be going bananas in 2nd if I redline 1st.

Is that your Stage 2-ish power?

Cant wait to see this thing, congrats!

What PSI is run on the base map, pretty good numbers on a base map. Can't wait to see more.

just installed my kit from @Pure Automotive saturday. what a blast to drive, even on the base map/ stock boost. im logging only 5.1psi as well, so @nataku should be very close to that. injectors, pump, 10psi and live dyno tune in the near future for me. im sure a clutch as well lol

Like @spitfire481 said, base tune is 5-6 PSI. Definitely need a clutch upgrade beyond this point. I think with a 93 pump tune with full exhaust it's gonna be cutting it close.

Yes, should be upping it up in the next month or so :happy0180:

Congrats on your build and numbers, it looks awesome. And those numbers for a base map are the icing on the cake.

Weird, from what i've been reading lately it seems the stock axleback isn't all that restrictive. Robispec is putting out close to well over 300whp (dynojet equivalent) and still has the stock axleback (i believe.)

especially since i hear the boost kicks in very quick on the 18gs. Have fun guys.

Numbers look perfect, all usable power. I want to see an FI car with these caliber stats come out and tackle the cones. I'm curious to see how Matt's times change with the turbo, and maybe take a spin :thumbsup:

You'll like my car now. It's all quiet and stuff. It's probably going to be completely bonkers without traction control at autocross though.

That may be the case. I still have to choose where I want the tune done anyways. By the time I make that decision I might have a different catback haha.

I doubt he'll get much faster. Terbo cars are generally more wild and harder to control. See: that kid in his 2.5RS whipping the kids in their WRXs. Not that Matt is a bad driver or the car is bad, that's not what I'm saying.

:paddle:

You're partly right though. Given that I was so underpowered before I expect to do slightly better, but not until I've figured out just how wild this thing is going to be.

You'll probably have some PTFB issues (manual boost controller I'm assuming?) and lots of fun losing traction mid corner when boost hits. It's just unavoidable in terbo cars, but at something like Summit Point you'd be hideously faster as you've gained a ton of speed on the straights that you can carry into the corners.

Yes It's manual, I don't have an EBC. I hit full boost around 3500 though, and I rarely drop below that many revs on the courses I've run with CDC at least.

I foresee my biggest issues being the shift point (CDC always puts it in a turn...) and slaloms where I have to modulate the throttle a lot. The turbo really doesn't kick in as jarringly as I thought it would.

Just need better throttle control is all. Holding steady throttle might not work, you might need to reduce throttle input as boost builds. Get the car to a happy place and find a way to maintain the power level such that the tires can handle given the amount of steering input.

Beautiful..

You're likely correct. Honestly, no one with an FI car has come out to ANY events yet, CDC, AI, SCCA. I just want to ride along (or drive) so I can finalize my hypothesis on if FI is worth it for autocross at all, or just good for the street/track.

Highway pulls! :burnrubber:

I've been to CDC once... on stock tires.

Expect me by the end of Sept ready to go sir.

Karen Kraus has some luck in her winning WRX with FI ;)

And by luck I mean championships, lol.

As for our car, I'm curious as well lol

Looking forward to seeing this

Pushing things further off the original topic but I'll just post a little here about autocross since the discussion occurred here.

I had no PTFB issues whatsoever, the throttle is entirely predictable. I did have the occasional issue with falling out of boost. This was mostly due to taking bad lines because I was understeering more since I'm just so damn fast now. I would come at a turn thinking I was going as fast as I would have been with the stock power, but actually I was going a hell of a lot faster and the tires just couldn't handle the turn in. For the record as long as I'm above 3000 RPMs there is absolutely no turbo lag.

Once I started to calm down and keep things in line I found I could keep on the throttle more than I thought I could, and started putting down very respectable times.

I ended the day with a 45.53 as my best (not one of my 6 that counted but whatever). I managed a 45.2 but murdered a cone in the last slalom. Any of the guys who went to CDC today can attest to these being pretty good times.

All in all I would say the AVO kit is entirely manageable for autocross conditions and delivers some extraordinary power on straighter sections. As with any FI car I have to be more careful with the throttle, but with some experience I have no doubt the added power will improve my times.

^^ I bet you were having a lot of sideways fun, I remember last CDC commenter when you were running where he was like I don't even know how you can get that turn sideways but you managed! hahaha
