Another hybrid conversion thread....

Wow, they are a bit all over the joint..... Especially the huge drop in torque at 3000 RPM, it doesn't recover to the same level until 1500 RPM later....

I know, very strange, not sure what could cause this, it needs work, but at least its going in the right direction, TBO i would have thought i would feel that drop in torque on the road but i haven't, it pulls strong.
 
Forgot to add this was on a MAHA dyno on 95 octane, us poor farmers over here can't get anything higher in octane:yes:, still the Methanol would have added stability.

No, they have a 4wd and 2wd dyno there, why do you ask.

Seen similar issues when S3's are ran on a 4wd dyno as the haldex has a spaz... Bill does all his mapping with the haldex fuse pulled in FWD only on these...

Hmmm, thats some weird old delivery... torque would be boost driven normally, does it spool then hold then go again?
Do you have logs of it?

No Logs it was just a power run, i have been thinking about this and i would 100% feel this on the road, i think it was wheel spin, if thats possible

Yeah, seen this on Bill's dyno... warming up the tyres by holding on load and spraying the tyres with a little WD40 helps them stick better as does proper strapping...

Did try strapping off the towing eye but the natural climbing action of the suspension when the engine came on boost would lift the car off the back roller causing a failed run and no coast down...

Now we just strap from the transport holes on the floor pan of the car just behind the front wheel arch... not had an issue since...

Well, well, well.

Quoted from Bill on the Hybrid comparison thread:


well.. hmmm.
erm

you know... erm.. when thing dont quite go as expected...
screened maf's descreened maf's flow more.. and all that jazz... and the extra power...

Or Not..

3" TIP fitted to wellys s3
comparison run to last time on dyno. differences being 3 inch tip, some tweaks to add more fuel to go with more airflow, and reverting to screen maf and....

well....
hmm....

was'nt expecting this result...

:thumbsup:

3inch tip airflow, descreen maf
272g/s max logged compared to before 3 inch tip where max was 254g/s, however on this car (non wideband) the apparent airflow and change to afr's made a difference. Clearly more airflow as it ran leaner.. added 5% fuel and it returned to as before, making slightly more power.

rule of thumb calc applied.. airflow divide 0.8 = power
we get 260g/s = 326bhp

pretty damned closed to dyno all things considered

:D
 
Ummmm, feels quick....

Different though. It spools much more like a big turbo now, and delivers it's power much more like one as well.

It's not at full spool until around about 3.5K RPM+ but once there it just pulls and pulls and pulls. Torque delivery now is much more pronounced than it was before, but this is due to the boost holding on better.

It feels like a BT car to be honest....
 
not bad then, big turbo feel for less pounds and less fabrication. the later power delivery must be made up by the higher rev limit, the go lasts longer if you know what i mean
 
The area under the graph looks very good now dude. I want to see this on a 1/4 mile to see what time and terminal speed you can get.

Me too.....

is it laggy lower end then...

Yes it is dude, quite noticeable under normal driving. Not a bad thing as the go further up more than makes up for it, and it means MPG should be better under normal driving.
 
even if it is a little laggy lower down, this should be good for day to day driving surely, and when on track or whatever, shouldnt be hard to keep it where the power is.

No, the power isn't hard to find.

My mate tried racing me up one of the 2 mile straights on the way back from Bill's. Wish I had a camera....
 
I would have thought so be but thats probably because theres a bigger/consistent volume for the air now but once the turbo on boost it getting a nice amount of consistent airflow so can hold the boost longer and higher up.

Nathan
 
Thats some cracking gains Welly, Bills been working his magic

I finally know which route to go now, IHI or Hybrid, Hybrid it is!

Cheers for doing the experimenting so we can all benefit!
 
i can see a hybrid battle at pod coming on hehe all looking good welly i take it youll be at Bills for the RR day
 
Wow! nice work, this has convinced me beyond doubt. Expect to see a lot of me Bill :thumbsup:
 
Now its worth mentioning this prototype was done for a car which had open cone induction kit.
Its going to be tight on an OE airbox, but not having tried that I cant confirm how well it will fit..
wellys S3 bung it in to check install below to show you what I mean:
