Stealth Club Vs The Rest

Took my TDi sport down to Stealth on Friday, results below:

Before:
BHP:78.3@3605
lb ft:161.5@2351

After
BHP:101@3784
lb ft:205.3@2217

Certainly improved the car overall, drives far better and overtaking on the motorway are a lot easier. Big thanks to Vince and the guys at stealth, proper job.
 
Joined the club..

I've joined the stealth club too!! Was in on Saturday to see what Vince could do for me.

Before:

81.4@4079
154.6@2340


After:
106.7@3321
177.5@2630


Bit disapointed by the Torque figures, but the air filter looks a bit dirty. So thinking about an upgrade to that. Cars not been serviced yet as its only done 16k. but smiles all around. :p

Finally at the third time of asking...

She's mapped....

Before
BHP 79.5@4046
lb ft 154.3@2280

After
BHP 105.4@3510
lb ft 177.3@2638

As with all these figures these are a peak point on a graph and don't show the point/band at which 100BHP is crossed and matained or the point that 170 lb ft is passed these are with a little interpretation from the graphs

BHP 100+@3050 - 4100
lb ft 170+@2000 - 3150
 
Good figures there, but interestingly, the intercooler doesn't seem to have made much (if any) difference to the result, which is a shame.

The new intercooler looks substantially thicker than the old one, so presumably has a more pronounced cooling effect, but this doesn't seem to have translated into extra power or torque, meaning that it isn't the limiting factor in the equation.

So, it looks like a bigger turbo is the way forward, along with a forced air induction system (if a way around the vacuum problem can be found).

Cheers,

Mike

From my R5 turbo days the intercooler never had much of an effect on a stationary test, due to the cooling effect. So you might see far better result on the real road.
 
Is there any difference with results on EU3 and EU4 compliant TDi 75 engines? The results posted seem to vary significantly on torque.....Haven't checked V5 yet but my TDi 75 should be EU4 compliant ( its an 04 plate sport) and just wondered if the changes to acheive the cleaner exhaust limit what can be acheived with remapping?

Where are Staelth and how much is thier re-map? I thought Awesome were supposed to be the mutz nutz with re-mapping A2's?!

If memory serves me correctly the TDI has the Garrett GT15 Turbo and according to various websites this unit is sold as a 100 - 220BHP unit so I dont think a turbo upgrade is necessary.

I do think the amount of air flow into the engine could be greatly increased..

Air intake - In front of front wheel
Turbo - behind engine - this is not going to move
intercooler - infront of engine - position could be altered
inlet manifold - fixed position

There is a vast amount of air ducting - one complete lap of the engine; and its not a big diameter duct - I would start hear as you have already sorted out the exhaust side..

Yes, I know what you're saying and induction will be the only thing I'd consider now. One thing though, on the TDi 90, the inlet is under the service flap, not by the front wheel.

It does do a couple of 180* turns from there though, which probably isn't needed, before exiting, and then there's the return journey to the front and the intercooler, before heading off again to the back, so surely some improvement can be made.

Cheers,

Mike
 
Not being totally convinced with my tuning box was thinking of going down the Awesome route along with FSD and 'front brake improvements. Thought the forum had a discount scheme with Awesome, when I spoke to them on Saturday all I was offered was a £50 discount from the total price of all the work.....

On the actual remap, there is a discount, but on general work, including fitting the usual prices apply.

However, when you take a look at those prices, they#re hard to beat: £293 for a full set of FSDs and labour at about £45 per hour - can't be bad!

PM Brads for the details of how to get the discount on the remap.

Had the car remapped yesterday at Stealth

old figures:-
81.1 BHP
157.3 TORQUE

new figures:-
104.5BHP
181.6 TORQUE

Very impressed with the speed of service and the final result, makes a big difference....nice 'whistle' noise from the turbo now too :D

As everyone has it now pulls right though the rev range too

Its a 1.4 2001 TDi by the way, thanks to the guys at Stealth!!
 
I had a quick look on the forum and Stealth seem to be the way forward, unfortunately I couldn't find any contact details?

Looking on Google I found a compant called Stealth in Avon..is that the one?

I would be grateful if someone could give me an idea on recent cost, eothe PM or email if it is not forum etiquette.....cheers :)
 
Hi, new member here. I recently took my Lupo TDi to Stealth for a remap. I chose them since they have lots of experience of working with the 1.4 TDi, plus there are lots of positive reviews from people on here. I felt comfortable with them working on my car, which is not something I can say about many garages!

Power:
old - 81.2 @ 3110
new - 108.9 @ 3339

Torque:
old - 162.9 @ 2317
new - 179.1 @ 2202

I had a 190 mile trip each way but it was worth it:). The only thing is that the power starts to drop off again higher up in rev range, Vince said the A2's tend to hold their power for longer, which could be down to the air filter and intake piping. I'm going to try and relocate the air intake behind the front grill like on the A2 TDi 90.
 
Getting mine done by www.supertuning.co.uk at 9 am tomorrow (wednesday) , having a day off work so thought I'd book it in. Read good reports about him on a VW Golf forum so will see how it goes. Quoted me £250, and I'll ask him about some K & N Air filters as well, see if they help. ;)
