you mean i got something right

holy badgers **** batman!!!!!

lol

so the correction figure would read different

MartynJ

It isn't a correction figure and is only there for the manufacturers info, nothing else.

I will be happy with that, an 11 sec 330bhp Impreza lol.

Ok here is the verdict from todays run at Subaru 4 You, it ran 364.5bhp at the fly (287.8) at the wheels, 335 ft/lbs torque, correction factor of 0.998, apexi was set to 48% duty to achieve 1.35 bar indicated on the dyno, AT was 17 and IT was 24 (the difference between IT at S4U and DSA will be down to the different setups of the booth and fan etc), DSA has the rollers set into the floor so the fan can blow onto the engine, at S4U the rollers are higher up so the fan blows lower down on the front of the car. The higher IT temps from earlier runs must have been from the temp sensor being caught in a freak flow of hot air next to the filter even though it was positioned no different to any other car run on this dyno. I feel that given the results found here today and from the runs at DSA it is fair to say that no further runs will be required and that the function and operation of the dyno at Subaru4You should not be in question.

Graphs to follow

Cheers Iain

Tidgy

i wouldn't worry about a few degrees difference in inlet temps from run to run, different fans, atmospheric conditions create different results in that sence.

can you post up the origional graphs, bhp, torque, afr, boost and then the new ones all in the same post. (saves people digging for them lol)

so whast changed between these and previous runs at s4u?

Big 'D'

The only thing that has changed between then and now is the design of the intake and the fitting of a cold air feed, the position of the IT sensor has been a constant, here are the graphs.

1st Run, 382bhp with an IT of 42 deg

2nd Run 382bhp with an IT of 33 deg, Len had removed the rubber weather strip above the drivers side light to improve the flow of cold air getting to the filter.

3rd run, after sorting the intake and cold air feed. Run at 1.35 Bar with 45% boost duty.



Todays run again after sorting intake out, Run at 1.35 Bar with 48% boost duty.



Cheers Iain

Tidgy

have you got a fuel/boost graph for the 380 runs?

p.s may have to ask Len to print em off for you if you havn;t got them, the runs will be saved on the dyno.

Nowhere near to taking Shaun's Dyno Queen crown, but from your last graph, you're up to 30 runs at S4U.

As a guestimate, I'd say it probably is around the 360bhp mark. Nothing shabby about that.

It's quite old now, and a Dastek set up, but my 330bhp graph for comparison.



Yours has a lump more WHP than mine, so I think around 360 would look about right.

The fuel graph for the 382.8 bhp run was given previously.

I do not remember a fuel map for the next run at S4U but it may have been lost in the milieu.

Comparing the fuel graph above with that from DSA and the last one from S4U is very interesting.


The result is, as I have said from the start and on several occassions, at the top of the tree for a VF35 and indeed very much in line with what I said at post #368 and elsewhere.

A lot of hot air and a storm in a tea cup really. A great pity Tail Slider was attacked in the way he was as a result of his previous post but this is afterall Scoobynet. Why let the truth and factual information stand in the way of a posse intent on entertainment and demonstrating their ignorance. Sad but very true.

I am pretty sure that ingnorant is not a word that people who know me would use to describe me and to be honest as correct as you are in stating the expected power output your manner throughout this thread Harvey has been quite rude. I have gone out of my way and so have S4U to get to the bottom of this and now we have a result which I thought that we could all be happy with.

I guess you were referring to this post of Tail Sliders.

"So, just to recap. You posted up that your car made 381bhp with a VF35 to which you put down to the uprated actuator and a ported wastegate. Harvey commented that because of the large difference between the AT and IT that the result was scewed and infact the result would be less if the AT and IT were within 3degrees of so. Harvey also mentioned that if this was corrected your car was still up there with some great VF35 results.

You and your fanboys thought because the numbers were there in black and white it was to be taken as gospel, even when other tech heads threw there hat into the ring you still maintained the result was the result.

Today you get it dyno'd, this time the AT and IT are within the range of what Harvey mentioned and you only make 361bhp!

Lesson learnt my friend."

I am sorry did I miss something somewhere, appart from the post being quite smug,rude and 'we told you so', it was stated in this thread that if indeed the IT had been a true 42 deg or 33 deg during my runs at S4U that the DD RR would correct the figure to what it would be at 20deg at a set PB etc so if it was that high when the IT was reduced to 20deg the corrected figure should have been the same or there abouts, so as it stood after the invest I had done on the 2nd run with the IT we believed that the IT was actually this high and had no reason to doubt it, throughout the runs the IT probe at S4U has remained in the same position. We even tried yesterday holding the IT probe within 1" of the pipe from the turbo to the intercooler just after several runs so the pipe was very hot, the highest radiated temp we could get from this distance was just over 20deg and dropped quickly as you increased distance from the pipe. The IT probe must have been sat in a flow of hot air near the filter when my old heatshield was fitted and there is no other explanation for it, in the end it turned out to be a false IT figure but it was not down to anyone doing anything wrong or faulty equipment it was just a freak set of events. We also asked about the TN figues and it was down to the twin retarders at DSA as to why the TN figure was higher (as mentioned previously in this thread).

What is interesting about the fuel graphs then Harvey I am keen to know.

I would like to take this opportunity to thank Len and the staff at S4U for being so patient and helpful throughout this power run saga, also to Shaun and others who have been very polite and forthcoming with information that was very helpful in aiding to understand a little more about the dyno, thanks guys.

I would also hope that none of the comments about Subaru 4 You being inexperienced DD RR operators would put anyone off using the facility.

We got the correct figures in the end and I am happy with that, who wouldnt be happy with an 11.80sec 1/4 360 bhp, 330 ft/lbs Impreza (running only 1.35bar) on a VF35, it almost sounds as unbelieveable as saying it had 382bhp lol.



Cheers Iain

Big 'D'

I wish I had your patience, I am not just going to bend over and take it in the *** no matter how well known people are, I have done nothing wrong throughout this thread nor have I anything to gain/lose or hide and have gone out of my way to get to the bottom of it and I feel we have reached a good result in the end.

Ignorant: Lacking knowledge, or learning. (Oxford English.)
Not sure Harvey actually said YOU were ignorant, Iain, and even you have to admit that you've learned some things during this thread, so maybe you were lacking some knowledge? Certainly, some of your more vociferous supporters were

Not really, Harvey has never insulted you, nor has he said anything against you except that he felt you were wrong, and wrong to question people with MORE knowledge. By all means ask questions of them, as do I, but don't presume to question others' hard-earned knowledge.

I'm sure all ARE happy Iain. You still have a car capable of an amazing turn of speed, and Harvey..........well, he WAS right, wasn't he?

Big 'D'

I have a couple in mind still in the VF range

Cheers Iain

Big 'D'

Sorry perhaps I imagined it all

I see its ok for Harvey to have a little following of 'Fanboys' as Tail Slider calls them but if anyone posts in responce on my side they are frouned upon and slated and I am the childish one. Hmmm

Cheers Iain

Tidgy

becasue no one doubts harveys knowledge except seemignly you. thats the problem. some of the most knowledgable poeple in the subaru tuning world have commented and you've claimed you knew better, bad idea.

also doesn't help when your backup doesn't know what a boost/afr graph is lol

alcazar

iTrader: (2)

What he said^^^^^^^^^

Big 'D'

This is all very one sided, have you even read the thread from start to finish, and I don't just mean Harveys post where he misused quotes to make me look like and idiot and claimed I was childish.

Alcazar. You forgot to mention the part about Ignorance that states that it is commonly used as an insult.

I don't really care what anyone thinks of me, I feel I have been open and fair and tried to be polite throughout even when I perhaps should have been a little more stern in reply.

Cheers Iain

Tidgy

its all very one sided? why possibly could that be? wild claims of massive results tends to make things a bit one sided because no one believes a word you say.

if i came on and said i got 310bhp out of a td04 i'd be laughed off the site, why? because you have more chance of winning the lottery that getting results like that because there things called laws of physics.

you aint gonna get much support when multiple tuners have spent thousands of pounds and failed to do what you claim you did on a few hundred quid and dont listen to what people are telling you.

im not saying its not gonna happen ever, but im sure even you'll admit the chances arn't exactly high.

Big 'D'

Wild claims, hmm, all I did was post up the first figures I got from the dyno, I can see now that that was a huge mistake, but then if I had not posted up I may may have still believed that my car had 380bhp, but no I stuck at it where others would have given up weeks ago and I am happy with the result.

I have taken alot out of this thread bar one thing.

What do you lot think is responsible for the improved performance of my car over many others of the same spec and turbo then. I gave my reasons but then I know nothing.

Full spec:
STD EJ20K engine.
IHI VF35 with ported wastegate and 1.0BAR actuator peak power at 1.35 bar (45-48% solenoid duty)
Walbro fuel pump
550cc PE Injectors
Parrallel fuel rails + FPR set at 3.0 bar atmospheric.
AB88 FMIC + Forge Atmospheric DV set to open at + 0.3 Bar
NGK PFR7B Plugs gapped at 0.65mm
Full decat in tubular headers and up pipe
Apexi Power Intake
Apexi Avcr boost control
Simtek ECU

1/4 PB: (from USC 2010 Santa Pod)

60ft = 1.7111
330ft = 4.8506
1/8 ET = 7.5374
1/8 MPH = 91.6
1000ft ET = 9.8
1000ft MPH = 106.01
1/4 ET = 11.8092
1/4 MPH = 111.26

Cheers Iain

Tidgy

pure luck, simple realy, sounds harsh i know. but different cars with the same spec can vary results wise depending on how close they are to tolerance, how far the end of the tollerance scale they are aka if they are all too big then they will be a good match, some to small some to big and they wont.

360 is still a great result for the spec dont forget that

MartynJ

Cough, lol.



Stock engine too !

You can pop that winning lottery ticket in the post if you like !

Tidgy

that on standard td04?

Completely standard and the original unit.

I'm with this all the way. Ask around. Some engines just make more power, some don't, ask any mapper if ALL engines are the same.
