Results from Dyno

[Subru]

Will post print outs later.

It was running a bit lean but after the air flow censer was cleaned it was all good. Its knocking a bit on high rpms . Turbo comes on late and runs at 18psi which he said was a bit low and makes 179kw at hubs. Could be leak or turbo stuffed.

Makes me want a tune even more...

Got aem fuel pump coming. Might get 3port and downpipe/decat too.

 

+1 for Chris at prestige tuning. He is a legend. Definitly gonna use them again.

Is that stock turbo bro? If I'm not mistaken that's pretty good power for a fairly stock v7 to be making pretune, especially given the age of vehicle now. can't wait to see what it's like after your mods and tune, have seen tuners work wonders on getting boost/torque on earlier with the stock turbos .

 

Just remember don't get stuck on the number, use the pre and post figures to compare improvements (I feel like such a hipocrit saying this tho haha)

[Subru]

Its stock turbo yes. It was a hub dino not the drive-on one, if that makes a difference. Yeah ive been told that its not the number, its the area under the graph that makes it feel good/fast to drive.  ill try and get the graph up soon, trying to assemble my AEM fuel pump atm  

[Subru]

Here are the numbers. lol look at the boost.

Don't worry that'll be beastly by the time you're done. Hub dynos will read different to rollers so long as you get your post tune dyno on same dyno you'll have a better understanding of improvements relating to what you've done since first run

damn thats pretty good for stock, i only managed to get 167kw at the wheels standard, that i guess sounds about right for hub dyno than, after exhaust, intake, fuel pump and tune i managed 220kw...shows the motor is fresh and still got life in it...

Yea, just worried about the knocking. Ima also get a boost leak test done (they pump smoke through the system to expose leaks), he said that its either a leak or the turbo is on its way out if its taking that long to spool up and it drops right down to 12psi and he said it should be doing up to about 20psi (18.7 is not too bad tho) and drop to 17ish. Im missing out on all that goodness after its hit max boost.

Also, wouldn't a hub dino tend to read more than the rollers one as the wheels are taken off? just a though...

[Batbaruman]

Yeah roller suffers some level of loss due to traction , just a tuning tool anyway end of the day . Did prestige check the log and suggest why it might be knocking?

[THUNDA]

Mate these are good results! pat that car on the back! ^_ ^

He showed me on a graph where it was knocking, he didnt say much about it or why other than Subarus usually have some knock but not as much as mine, he said its not serous but to be careful...

I did

Just curious, what boost controller are you using? or are you on the factory? pretty sure its normal for factory ecu to ease off the boost pressure in the high revs anyway.

My td05 was its healthiest (or erm.. power creating/boost/det efficiency) at 16.9psi on my factory block,creating 187kW AFTER the tune on the g4 link. if you include the cost of work I did to it to get it ready for dyno (incl link g4 and tune) it was in the vicinity of 6-7k. So thats really good power imo considering you havnt had the full tune yet?

This next lot of mods im doing is est. 10-15k, im already 10k deep, and with the new rays wheels add another 2k on that, and my heads are likely to be 3-4k, then another tune ontop of that. so already blowing the budget LOL, but that also includes my brakes, killer clutch and pretty much everything being replaced with hi-quality parts.

Im really really looking forward to my next tune results

Its factory boost controller but it looks like its easing off too much boost, maybe im wrong tho.. 

Damn that sounds like a nice build... and expensive

Yes expensive, but hey its one of my many crazy dreams you only live once, believe me ive had lots of thoughts of "maybe i should have started with an sti" but theres something about how worn out/rough/dirty the bc5 is that i love, and after having it on the track, well im just addicted now I guess, there needs to be some "racetrack anonymous" meetings

lol just realised they would be "R.A" meetings hahaha

as for your boost easing off, id defo rekon its your ecu, with all those sensors, it knows what its doing, be surprised if its a boost leak but hey maybe, tbh 18psi sounds high for factory boost but ive never driven an sti

[gotasuby]

Factory maps are meant to be around 18psi and drop to 13.5 so yours is round the mark. 

[Guest]

Generally V7 sti tunes are a bit rich so wonder if someone's already played with it. 

 

Good S*** for getting it run up on the dyno. Now you can see and feel the difference.

[BeastGRB]

Could be irrelevant information but thought I'd chip in. I have an 08' STI model. Mine is pretty much the same as yours in terms of tapering off however not as much as your having. My peak is 20PSI which tapers high in the rev range to about 16-17PSI. I also have a boost gauge to record. I had a dyno run probably a month ago or so to see how it's doing.

Yeah.

Im also glad because it was running lean and if I had not done the test, who knows how long I would have driven it like it. Everyone should do this if they buy a Subaru, Im going to from now on .

pretty much all stock Subi turbos peak early and taper off, that early hit of torque is arguably a big factor that makes them so fun/attractive . only really when you go aftermarket tune/turbos where you see them maintain higher levels all the way through

You can hold 20-24psi to redline on some before they start pushing hot air on pump. Theres no hard and fast rule.

[pedro]

Use the gearbox to take advantage of the torque..

That's what its for..

Running engine to redline will shorten its life..

[boon]

What fuel was in it?

 

If you say anything but BP98 I'm going to cry.
