Hi Leighton,

Excellent table.

One question, can you point the reason between the torque vs. boost rates. There are cars with same turbo, but boost/torque values are very different.

For example two Coupes with GT3071R turbos, same boost, but huge difference between the torque!

In my Coupe both GT28RS and GT3071R have been given quite similar torque values with same amount of boost.

Regards,

Jari

That I've wondered about too.

Since you have WI can i count my 28r with nitrous

I claim highest RSR then,

Depending on Flea's availability, I hope to be on there just after New Year, it's just going to be too tight before Xmas, unless you're working between Xmas and New Year.... ;-)

and i seem to have the highest standard set-up......

Jari the three cars with GT3071R's have different engine setups, so that will probably be a big factor in the difference in torque.

Yes, they are all quite different in terms of specification. Luke also had a small exhaust at 2.5" with the decat pipe only 2.25" so very restrictive. It did sound like a jetfighter though!

Of course some engines respond better for reasons that are are not always overtly evident, that's tuning for you...

Okay, now I understand .
Yes, the exhaust like that is really very, very restrictive.

So, the list is not that simple at all. The values are not necessary comparable, if you don't know the whole truth of the setup's.

Anyway, list like that done in very same RR is excellent. That's why we always use also the same RR everytime to see the difference after what ever we have done.

-Jari-

yeah, smaller exhausts sound like jets in coupes with more than std power or with decats, scares passers by!

I agree - my car is quieter with a full 3" system than it was with the SuperSprint

Any idea what my old one put out after you mapped it Flea?

Woohoo, I'm now on there and making 'bout tree-fiddy' before the 3" downpipe

could you change owl10 to ryangt ?

Yippee I get to go on the table next time its up-dated...
Car runs GREAT after Flea's done his stuff.

not many 16vts anyone had theres mapped and know their results??

How much power, Fullpint.

282.9bhp, Flea seemed very pleased not only with the result but also the health condition of my Coupe which was nice to hear..

Cool...

what kind of power would i get from my 16vt fully standard apart from fmic

Unfortunately there are very few 16vts about so the number left for mapping is quite limited. I have done four now although only one has been on the FC dyno!



Assuming the car is healthy and producing a standard 195bhp, then I would like to see somewhere between 230-240bhp. Of course it's not just about the headline figures, gains will be made across the full rpm range including off boost and part throttle.

sounds good think ill book a day down in summer how much for a live map and a rolling road

And i'll be back again in a couple months.. Bigger and healthier than last time! Map is deffo gonna need tweaking... Then maybe I could sneak into the TOP TEN!?

Flea, have you ever had a car on the rollers before and after the remap?

I was thinking about the results my hybrid made the other day. As you know it made 292bhp at Track'n'road on the GTiR but I wasn't able to get a booking at Circuit Motors when it was mapped.

The mapped RS did go on your rollers (Circuit Motors) and made 342bhp but subsequently made only 315bhp at Track'n'Road.

I know you explained how this difference could be caused (I won't get into a 'rollers vs' discussion gear used, heat soak, inertia vs load etc), but adding a fixed % gives me 317bhp, adding a fixed figure gives 319bhp.

What do you think the GTiR would have made on your rollers?

The GTi-R is the same as the Hybrid S2 (both 60mm compressors), and as you can see they average 285-295bhp so the same as your Track n Road 292bhp run.

The GT28RS 0.86 is a big turbo and can flow up to 380bhp no problem, so your current 342bhp is just tickling it at the minute until you get some exhaust upgrades.

im loving how im still managing to hold onto a spot in the top 10 after selling up!

seeing my figures makes me really miss my coupe!

never new the rsr could put out that much power

Yippee Im on the table.

Damn.. I would if I could.

Extremely happy with my figures on standard internals
