Right, just got home and the car is AWESOME the Anti-lag is just wrong and the Launch Control too.

I've put the graphs on the first page of the post.

Thanks again to Mark/ Dean/ Rod...transformed the car...

Mine is stronger upto 5600rpm

It dies after that compaired to yours

Steve.

lamb chops

wow cooooool Pete bet your well happy!!!

you will have to take me for a spin at some point

Fiecos Dan

, sounds good.


A few questions tho,


on graph,

spikes 27, holds 25, tails off to 21 psi.


Also looks like it werent either loaded up correctly or mega slow spool up.


What does it bost on the road, and where does full boost come in?

Staffi

iTrader: (1)

Dan, spool up is slow, it's peaking @ 30 psi on the road


Goes very well, BUT i defo need more low down..


Just need to start saving now again ...

Fiecos Dan

so on the road what Rpm roughly does it hit 30 psi?


Does Mark think the cams are the reason for that too?

very nice m8

CosKev3

Sounds good m8

Did MAD convert it to 4wd for you too..................

Cause your old 3 door scared you away to the land of the rising sun for some gay 4x4 traction ,and that was 100bhp less than the Saph!!!!

Karl

Hi Pete,

Your car will never make more low down power whilst you continue to use the version of T38 you have. I have mapped several cars with your turbo on, and none have made significant power below 4000rpm even on different spec engines.

Regards blaming the cams for low torque, remember they are quite a wild cam and hence inherently better at delivering power higher in the rpm range. Nevertheless when I mapped your car in Jim's ownership it made 390lbf ft at similar boost levels, so its a little low at 350lbf ft.

I'm still not quite sure why you did'nt discuss changing your turbo etc with me before changing your mgmt, but as long as you're happy that's what matters.

CharlieSaff

Karl, what do you think could be the reason for the drop in torque, obviously there are laods of factors that could effect this but any ideas?

M.A.D.RST

Did you not see my reply to 'that' post on the mlr!?

Karl

Charlie,

To be fair the turbo is awfull. All the lag of a T4, without the power of a T4.

Regards why its dropped from 390lbf ft to 350lbf ft, I have no idea. I remapped the car recently for pete, and felt I had increased the torque from the previous 390lbf ft, so to see a reduction is most bizarre.

As another good example steve (Dingy) runs an identical spec engine to Pete (i.e. pistons, head and cams) and running a T4 makes 410lbf ft/490bhp at 26psi, 450lbf ft/530bhp at 34PSI, so its not striclty true to blame the cams, although as mentioned above they are more tailored to high rpm power.

Dave, the car feels lovely to drive on the road yes, pulls really well, would like some bottom end but i'm sure that can be resolved at a later date..

No bodies man me mate....

I wanted to go with the Autronic on the car and then a GT30 early next year and Mark was the person i wanted to carry out the work for me.

He did a great job with my Evo so WHY go elsewhere??

Mark Shead

Dan

Pete does not like the mechanical driveablity of the engine not the boost threshold and the engine was realy specced for another owner for a diff output than it has now,
I recomended to Pete to change the spec of the cams this will IMO bring back the area that he is missing.

Mark

Mark Shead

The turbo is flat out and cant deliver any more boost as adding more preload to the act will only increase exhaust back pressure and likely to lead to more problems.

Mark

Mark Shead

There is no drop off in tq from what it had when it arrived at my place there are only improvements,
The diff in the TQ it could have had measured before could be the diff RR and the what the rpm was calibrated to it.

Mark

Fiecos Dan

Thanks for reply,


On the road does it boost the same as it did on the dyno run?

27psi @ 5000 rpm, as that seems either
it werent dyno'd correctly,
it wasn't loaded up till that rpm?
or a issue with the motor.

Mark Shead

Dan

It was run in 3rd gear and the boost responce is lethargic this is why the graph is like that, To get anymore boost you need to run more load on it just like on the road so you only get a couple of more psi in 4th and 5th.

Mark

MikeR

I am sure it shifts still


Mike

Fiecos Dan

Fair enough.

Staffi

iTrader: (1)

Mike, it goes very well yes, BUT the lack of low down grunt is annoying, but you can drive round that if you get my drift..

It'll soon be sorted anyway, spoke to Mark about future plans for the car, so looking all good..

Nice SIG by the way..





Dan, exscuse my lack of replies to you, i'm not brilliant on knowledge on RR graphs..

pete mcrash

iTrader: (1)

if we have the same turbo,how come i make power lower down..???...is it ur cams.....

cossie4i+

iTrader: (15)

I think that has a lot to do with it Pete

Steve.

Staffi

iTrader: (1)

Pete, i think so yes, as Karl as said, the cams Jim had in the car are suited for high revs. Jim originally had a T4 on the car, BUT didn't like the lag he told me so he PX`d it for the UT T38..

Fiecos Dan

No prob's, thats what i thought.

Staffi

iTrader: (1)

It's the first one i've had done..

We all have to learn..

CharlieSaff

Here's Jim old graphs for comparison if its any good

bud-weis

i've been away 2 weeks and all this has happened

you have too much money methinks!!


i have the graphs from Weston Performance handy, i can't see why the torque would be lower??



I think when you remove that turbo you should give it to Karl to smash into a thousand pieces, he really doesn't like it

maybe it has a broken turbine blade??

Staffi

iTrader: (1)

You're old news now buddy..


How's Florida..


So looking at those graphs i've lost 30+ftlb..

bud-weis

lol i'm back now mate....got the copy of Fast Ford too, MY feature looks good (even if my pic is fuckin awful )

IF we go by the graphs alone then yes the car has lost a fair bit of torque, however the only real way you can compare is to pop down to Weston Performance and run it again, that way you have a back to back comparison, even DD rollers may differ from one to the next.

also if you have lost that torque i can only assume it's the different mapping or a mechanical fault somewhere.

give me a bell tomorrow and we'll chat

Fiecos Dan

Not really.



looking at Jim's old graphs, It was run up in 4th gear, so will read different.

bud-weis

this is mine from memory the red line was first run ( 424bhp/388lb/ft ) and the blue the second ( a bit lower )

Jim Green

Been away for a couple of days..........and I'll explain why later as I don't want to hi-jack this thread.

When I had the engine built by Karl....I asked him for a 400bhp engine that would produce a genuine 400bhp on anyone's rollers, and it had to be reliable, and with room for improvement at a later day.....(Bigger Injectors and Turbo). So obviously the engine was specced (Cams, Turbo etc) for 400bhp. Which Karl easily exceeded.

As Pete is now upgrading the engine, the obviously some of the spec of the engine will need to be changed. The Universal Turbo's T38 isn't going to produce anymore than it is at the moment, as it was designed to give around the 420bhp mark, so it will need changing for further power. The cams that Karl specced were as I asked......Mid - High RPM Power, so these also may need changing.

But 442bhp is brilliant bearing in mind the Turbo, and Cams that it's on at the moment, I think the most a UT T38 has ever recorded is 446, so it proves that the rest of the engine is working very well.

Great work by Mark, and I'm sure the Autronics will make it drive so much smoother than the L6 that I had it set up on.

Great work by Mark, and I think we can now truely refer to the car as "Pete's Saph"

Jim, Pete`s Saff.

Agree Jim, Mark got 442 out of it which i think is fantastic, it's very smooth on the Autronic and fuel eco is better aswell..
