reccomendation- stealth racing

[loopylindsay 0]

me and my guy went to stealth racing on monday i found it quite enjoyable as ive not had a car dynod before or even seen one being done. it was rather scary too it sounds like your cars about to blow up.

 

i had my standard 16v set up on the dyno fuel pressure/wur mod and ignition timing then a power run at £65+vat for about 40mins. i started out at 133bhp and finished at 137bhp.

 

the guy said that my engine hadnt even started to loosen up yet due to the miles (66,000approx) and that it needs a good thrashing (wahoo permission to thrash). for all of you that havent had theirs dynod and want to know what it may do the guy said the 16v's loosen up at 100k miles and that they usually do 155bhp approx.

 

now the mk2 vr6: it had a remap at £275+vat or £250+vat depending on wether its a soldered in chip. it made 196.9hp at 5846rpm + 193.7lb ft at 4183rpm before the remap and 206.5hp at 5790rpm 205.6lb ft at 4066rpm after mapping.

 

it makes over 160lb ft from 500rpm and climbs steeply to 205lb ft max

 

they definately know what they are doing at stealth.

good stuff, nice to hear

 

i'm still planning to take my car up there and get some bits done, deffo geometry, but may get them to give the engine a once over (i'm not sure what i'm looking for when i look), but its sounding a bit noisy these days

well they are decent guys that know what they are on about so if anythings up with it they will find it! even just to take it up there for a health check and to see what it does at least then you know theres nothing to worry about.

Been going to Stealth for years, and always recommend them to friends / colleagues who run into problems with their VAG cars. Everyone I know who has gone to them has been happy. And any problems that do crop up, they fall over themselves to put right.

 

I'm off dropping the Corrado off there on Wednesday for a service and some other bits and pieces :) It's great living 8 miles from one of the most well respected VW/Audi specialists in the UK ;)

:eek: I moan about paying £33 an hour at RKE - lets hope they dont read this thread! :lol:

[Supercharged 2]

Thats rolling road time Walesy - you have to appreciate the overheads but I think thats a fairly standard charge for a 16V WUR mod and setup, it might have taken over an hour but it sounds like it wasn't far off to start with.

 

Stealth are the 16V daddies!

[Walesy 0]

Yeah I was talking about RR time too, just down here in the back of beyond, I'm not saying its OTT, just that i'm glad the specialist I use charge Cornish prices :lol:

I know this is slightly off topic but can you re-map a standard vr6 to squeeze a bit more out of it? Once I finish all that needs doing on my vr I would be quite keen on going to Stealth to see what they can do.

thats what they did in the first post??!

 

it made 196.9hp at 5846rpm + 193.7lb ft at 4183rpm before the remap and 206.5hp at 5790rpm 205.6lb ft at 4066rpm after mapping.

[mort1414 0]

so a standard car that has been remaped can potentially be running 205bhp ish thats gd tp no :)

[loopylindsay 0]

it can be remapped but the mk2 is not standard!

[mort1414 0]

what modifications has the mk2 got was the convertion 2.8 or 2.9?

[loopylindsay 0]

the full spec is

 

2.8 obd1 dizzy

schrick 268's (possibly 264's)

grant motorsport head

raceland 6 branch (heatwrapped)

decat

2.9 inlet manifold

amd throttle body

neuspeed pulleys

raceland flywheel

Nope it was a modified vr6 and a standard 16v, I was wondering for a standard vr6 :scratch:

[dukest 0]

ah well, my mistake, 195 is what the average 2.9 VR puts out and as they didn't mention any mods it sounded normal to get a nice increase like that from a map. mine put out 205 when standard and unmapped too...

[rajarella 0]

mine put out 205 when standard and unmapped too...

 

That sounds interesting, there may be hope for mine yet then! Cheers mate.

I wouldn't get your hopes up. You'd not notice 5bhp difference on the road. Better to leave home ten minutes earlier every day and get cooler air into your engine - it'll make just as much difference!

And look at the @wheel figures on a rolling road - that's the only thing that's measured. The crank figure is a finger in the air job. Ok Vince will say that he has his reasons to trust his rolling road, and it *will* be consistent amongst different cars, but the fudge factor can't be denied.

wouldn't it be 15bhp? Is the standard 190bhp that is quoted measured at the crank and not at the wheel? Or is it that 205bhp quoted by Dukest is at the crank and not the wheel?

My standard unmodified VR6 put out 201.3 bhp on Stealth's rollers, so... Now it's mapped and Schricked it's down to 199.9 ... assuming everything else is equal (it's not, the engine wasn't reading the same temperature).

 

And numbers like 205bhp are always at the crank, unless you're running turbo/superchargers..

I'd always take rolling road figures with a pinch of salt.

 

You are a lot better just driving the car and feeling how it feels! You could have two cars showing 250bhp on the same rolling road and they will drive completely differently. It is all very well banding on about power figures but really it is all about the power and torque curves and not the final figure.

[vwdom1 0]

the mk2 vr is mine and it wasn't night and day faster but its got so much more torque lower down the revs the torque graph is more impressive than the power he got the peak torque to hold much longer about 1500rpm rather than 1000rpm he thought it was a 2.9 :lol:

 

if i can figure out how to put the graphs up i will
