Hi Shaun,
Agreed the graphs are very close power/torque wise at the top but i did gain 20bhp and 20ftlbs at 4500rpm with less boost so that can only be a plus factor,the car was ballistic before and is even more so now.
The simtek i had in my car before did not control the center diff in my 6 speed dccd box but the syvecs does,this has made a world of difference to the driveability as the ecu now controls the diff on the fly making the car so smooth to drive in any sittuation,the car is no longer *** end happy and does not try to kill me as it did before.
No the syvecs wasnt free but the sale of the simtek almost paid for it,and with the deal i got from Kev and the clinic team i would have been a fool to refuse,obviousley i was right to accept as the results speak for themselves.
Glad you like the graph.
Glenn.

Apologies as I'm quite facetious at times. Nothing meant by it.
I suspect you have said all of this before and apologies for asking....
I assume you're not on VVT heads?
The graph prior to this one was on a 5sp box was it (it's now a 6sp'der)?
I can see that you gained torque and power over your previous graph at 4.5k, but I suspect this was down to the different gearbox?
Something that no dyno graph really shows is real world driveability, which you suggest is greatly improved. Above all else, this is the main thing in reality.

Hi Shaun,
No worries dude im use to you by now mate and know how to take you
1.Correct mate im using standard sti v5/v6 non AVCS heads.
2.No the graph im refering too was not posted,but here it is just for you.
3.No the gearbox was the same 6 speed dccd box,the graph shows 3rd gear but it was actually 4th just not changed on the dyno this is mentioned on the previous page mate.
4.Totally agree with you its def how the car drives on the road 100%
SORRY the direct image code to photobucket wont seem to work.

Apologies.
Kev,
You got anyone lined up to test the SC50 Billet TS on a 2ltr yet?

In answer to the first question, no its not been tried, sorry.
Question 2, see post number 3486 thats on 20% meth mix.
We are mapping the same car Friday on straight V power so will have another graph to show you, however the SC 42 has easily done 420 BHP on V power on a number of cars with the correct supporting mods of course.
cheers

as the twin scroll guru you may be interested in this overlay.
Blue trace new SC36 B twin scroll, red trace VF37.
Boost and AFR.
Normally we expect a bigger turbo to loose spool and gain power but the all new SC36 B Billet twin scroll has gained every where.
Its the same car and set up on both turbos, though the new turbo was on a 20% meth mix and the VF37 was on E 85, which normally helps with better spool and more power than a 20% meth mix, all this equates to show just what an improvement the new SC 36 B Billet is over the stock VF unit.
cheers
Kev
Like having the same turbo (its characteristics)... But without ANY downsides: i.e. produces a constant % more power/torque over the full rev range, but suffering no spool-up loss whatsoever!
Win-win-win!

I was going to ignore and perhaps I should? but I think the graphs on the simtek v syvecs are being mis-sold, I dont want to start some mass argument but I can no longer sit back and watch the bs without posting my opinion.
When the 496 run was done the DCCD 6spd box had been added but was not wired so the dccd was open so mainly rear wheel drive, and also the car wouldnt stop wheel spinning as the tyres were wet and was strapped very hard to try and stop it wheel spinning.. it didnt spend a massive amount of time on the dyno to fully dry the tyres and was run in 4th in an attempt to stop it wheel spinning..
The straps were never loosened to see the true normally strapped figures, the main reason the car was put on the rollers was to see if there was more to be gained now it was on a 6spd and the answer was no.. there was no more in it.. it is therefore not running less than it was when originally mapped on the 5spd box which is this run
therefore this 6spd run in 4th although labelled 3rd is not really a fair comparison to the more recent run

I also notice the dyno fan has become less efficent.. 15degree difference in air temp to intake temp, which will influence the correction factors.

But.... regardless of that, your lowdown parts of the graph (say up to 3500rpm) are very impressive.

Hi,
I posted up the twin scroll overlaid graphs for interest only, its not to be over analysed, its purely to show the two turbos back to back, I stated the fuel was different, but the fact that the E85 would help the VF37 spool and make better power shows just how good the new SC36 TWIN SCROLL billet is.
Cheers

this isnt a battle of mappers its purely an exercise to see the difference between the two ecu's, Glen was happy with his car on the Simtec but even happier now on the syvecs as drivability is far better all round and it controls the DCCD.
Incidentally the correction was in your favour by just 0.8%, best part of bugger all.

Hi,
why don't you come and drive it Shaun, you may be well surprised.
It is still a good comparison in my opinion, you are of course entitled to yours.

Hi kev, i noticed hammer man is running a sc46 twin scroll on his 2.5. might be way off here and if so please point me in the right direction coz i honestley dont know, but i thought jdm's were all 2ltr? and a twin scroll could only be run on a jdm?

Like I said in my previous post.... very impressive.
Now... if you had a SC46 & SC50 TS Billet on a OEM JDM 2ltr Newage for me to "come and drive", I'd certainly make the effort to come and see you!

Hammer Man has a UK car which has been converted to twinscroll and moved to a 2.5ltr as well (from a UK 2ltr).
.... And satisfying! lol
