DPJ's GTRS Eliminator Install and Development

[DPJ]

Dave
........There's no point flooring it out of boost. Change down and keep it where it's happy.
......... In the meantime, don't get too obsessed and just drive it.

So what sort of power are you getting from this now?

I'm honestly unsure. All I can say is you don't get 60-100 in the low 5s region in an underpowered Leon.

It'll be going on Awesome's rollers at the end of April, unless I do something else beforehand.

Would you say its a worth while upgrade over my gt2x? if i was getting the turbo cheap enough?

Yes, I would, but with what your planning to your engine, I'd be going bigger than GT28RS.

be interesting to see what you get dave. my guess would be 319/319 ... ive a bag of dyno lottery quotes incase its higher..

seriously though i reckon 320-330?

What sort of revs are you on full boost by?
Sorry for all the questions

I think I'd be happy if I saw 310+ on a credible dyno, Pat (suggestions appreciated). I honestly have no idea.

At the moment, I'm debating whether to get it custom mapped to suit the setup (with change of exhaust manifold) - or to take the eliminator off and fit a full GT28RS - involving change of DP too.

See you can still get equal length manifolds for these http://www.tig-art.com/home

Not a problem

3320			1660 mbar	
3600			1850 mbar
3880			2170 mbar	
4200		         2450 mbar

It gets to peak torque at about 4750 rpm

i think tig-art go through jbs in the UK

lol, all this work and your going to go gt28rs, you must be mad

although i would imagine you'd get a bit for your eliminator kit as you have made it more 'bolt-on' than when it came from atp!

did you ever get any headwork done dave?

Interesting.
For me, I can't quite see the point in throwing a lot more money to keep the standard K03 positioning.

credible dyno......
doubt thats been invented ...

but it would be good to put a figure on your efforts. pity your miles up north as our cars side by side would be interesting

That's the thing Saul. I do think I could get some money for my DP, mani, eliminator, inlet side and conversion - maybe even the Revo St3 ecu. I can hazzard a good guess as to where a full GT28RS would gain over my setup. As with most tuning, the cost increases disproportionately to the gain.

did you ever get any headwork done dave?

No, this is my dilemma! I would love to do the internals and fit a large port head etc. I can justify having the car as a toy. What I perhaps shouldn't be doing is committing to the time needed.

On the other hand, it would be satisfying to get the eliminator /wmi running (mapped suitably)at its best - to a reasonable proven bhp and turn round and say - hey, that's what you can achieve with a bit of effort and an average spend.

So it's either

• Bring the project to a conclusion soon with a set final spend
• carry on developing and spending big time.

No, I think Awesome's is a credible dyno (not that I've ever had a good result on it ) and there are a handful of respected ones round the country.

I agree it would be nice to compare the cars, it's a shame the central dyno meet never came off.

No going off home early in a Huff if you don't get the figures you want this time

Nearly three years ago and you keep bringing that up!

I stayed for 2 hours after my run - getting more and more pissed off. I didn't really know anyone then - now however, I can put a name to the faces that are avoiding me.

(for the few who don't know, first dyno run for the car. I fitted an N75J the night before (clever me). Would anyone like to see a graph of a Stage 2 Revo car running in limp mode? )

Awesome GTI SCN rolling road day 26/04/2008

The following graphs are mine, then Jonah's.
Both Revo Stage 3
Mine, GTRS Eliminator kit.
Jonah - full GTRS Backdraft installed kit.

[DPJ]

I'd take a guess that Jonah's better torque is the result of the big early boost spike - and that he would benefit from using an mbc in parallel with the N75 to control that.

 

[ibizacupra]

LOL - thats uncannily similar
Wonder what specific code to suit would make?

same boost on both, same ign etc?
