944 turbo wastegate

[Dowling]

Hello Pete
I had Augment fit their full ecu and wastegate package to my 1991 944 turbo with around 96,000 miles several years ago. I kept the original wastegate as it was okay (I had some spare funds and wanted to try a little more power) and photos should appear below. Just one of the eight studs broke. I haven’t touched it since but whilst taking photos of it tonight, I put soView attachment 3236View attachment 3237me spray release on it. PM me if you’re still interested.
Regards
Bill

Hi Billy, thank you so much for the heads up on this. Your one certainly looks better than mine. I’m currently leaning towards going for a new one, most likely a Lindsey dual port one with a manual boost control. I was thinking this means I could also do away with the cycling valve as a result- this set up looks a bit prehistoric. Thank you so much for the offer though. Ps- what was the feel of your car like with the Augment set up?

Hi Pete

I might still have my old one around somewhere.....

Pete

Thanks very much for the offer, I think I’m going the way of a dual port set up but thanks again for the heads up.

Tial is all new whereas a Lindsey is a re-worked original, but if you want more power then a dual port is the way to go, It will need more than just the wastegate though and it is the top of a slippery slope!

Thanks Tony- yep, I can see how this could get out of control. The main objective is to try and make it less laggy and a bit more responsive. My last turbo felt a bit like that. I’ve just had the turbo rebuilt, not upgraded, but I’ll probably go for an upgraded fuel pressure regulator to safeguard against it running lean.

 

[Dowling]

Yes, tongue was very firmly in cheek Pete!

Ha ha!! I wish it was 16 valve. It’s as standard as the day it left the factory albeit the previous owner had a boost enhancer fitted.

It must be 16 or 17 years ago now that I signed up on here. Back then it seemed every other week some new poster was asking what chips would give 400 or 500 bhp.

I would always be worried about reliability and head gaskets etc with that level of power. This car is a cabriolet so will never be a track beast. A bit better over standard would be perfect.

Hi Pete

Its the LR dual port that I'm talking about, have it somewhere with replaced spring and diaphragm, fitted it about 15k miles ago before I upgraded a to a tail a few years back, plus internal 5mm spacer to hold gate closed for longer. If I still have it that is....will check if interested.

All I'll say is that there's nothing hamstrung about my build and when talking 968 turbo, Porsche made it 8v even though they had plenty of experience with the earlier 16v 924 GTP. nuf said...

AFAIK know Pete, the 968 turbo was built by Porsche for a hp limited race class. And the Mark K and Rick Cannell 8 valve 2.5 turbos both dyno'd around 400 bhp, albeit with a laggy LR75 turbo. Plus Jon Mitchell claimed years ago that he bettered that from a 2.5 8v too. But there is no replacement for displacement, and another 8 valves. Whether torsion beam rear suspension can put down 400 bhp+ is another question.

They can and a lot more going from reports of other builds..

Sorry- with you now. That would be amazing if you still have it. Would love this.

I would love to experience the drive in a turbo producing that much power. I’ve always wanted something a bit more stripped out and track focused. The Mark K car- was that the maritime blue turbo built by EMC motorsport a few years back?

My standard estate car can do 0-60 mph in under 4.5 seconds, from a 2.0 engine, using AWD and a DSG gearbox. And probably not a lot longer on a wet road. No skill involved, old duffers like you and me can do it. It's called progress.

Yes that was Mark’s car.

400+ is very addictive, proper suspension setup, decent wider rear tyres and a modern turbo that’s a lot more progressive and it’s a joy to drive. It probably puts down the power better than my Vantage TBH, in the battle of the Eldavo-Transaxles that is a real handful out of slower corners, 2nd gear is just a traction-control-fest! (I love it)

Wasn't it his red turbo with all the Lindsey parts that made 400 bhp on the dyno day. The blue one was his race car? A bit before my 944 days, must be around 17-18years ago.

As best as I can remember Paul you are correct...owning a 944T was big fun back then...

I remember seeing that car at EMC and thinking how great it looked. Apparently was quite a legendary, I even looked into the back story about how it was made from an original turbo s. I wonder what happened to it?

Thanks Eddie, 2 secs I’ll take a look…

Hi Eddie, sorry I can’t see your message in my PM’s. Is there any chance you can try resending it? Many thanks, Pete.
