Can you explain a bit more about how you get the extra 30bhp, the likely costs involved and how much of a pain it will be to sort - any idea of the costs of the inlet pipe change - if you reckon 30bhp - is there a lag sacrifice.

Will be very interested to see what I can get at PE next week (assuming I get a run) - then theres the water injection......

Will this new 70mm inlet fit on a Bugeye?

Andy very kindly sent me a front entry cover at very short notice (got in contact @ 3pm - front cover was with me next day (saturday) and 9am!!!!).

A very good service!!

Beware of fitting an uprated actuator Rob, you can overspeed the compressor and end up with a pile of scrap Mark should be aware of this from recent experience.

Andy

tweenierob

Lol!! I Cant see there being a prob.
Wasnt nessecarily (sp) an uprated one mate, just one that fits properly... The weld on the Actuator arm broke and looked a bit messy (was a quick weld again but would have pissed me off if i had of been heading for a 10 up the strip), Mark suggested fitting a proper one rather than a cut n shut (So to speak)
this time. Not knocking your turbo's at all mate, just weighing it all up i am better off with the one from Mark.

Andy.F

I do hope not Rob Although I have heard that said before, shortly followed by "I can't understand why it failed" and "it must be your car"

Can I ask why you didn't opt for the "more suitable" Garrett compressor adapted version that Mark is marketing ?

Steve - I'm still testing the latest upgrades, a rolling road run today didn't verify the 30 bhp gain shown by the AP22 on the road. Looks more like 12 bhp although I changed a few things at once on the car so it wasn't an ideal comparison. The peak power doesn't tell the full story however as there may also be gains in the midrange. There is no increase in lag. I'll keep you informed of progress

Fuz - It will need a custom pipe. If it is sucessful I'll look into making a pipe to connect the turbo to the latest Samco type intake pipe.

All down to Budget mate
Plus i am familiar with the TD05/06... after having yours.

Yes it can be run at 1.3 on a dawes without surge. It will run approx 380-390 bhp at this boost. Any more boost and you need to use either a mappable ECU or a boost controller such as the AVC-R to steer clear of the surge line if running high boost at low rpm.

Boost creep is very car specific, it is dependant on the breathing ability of the inlet and exhaust systems on the car. If the car has a very free flowing inlet and exhaust and you want to run low boost then this can be achieved by porting the wastegate. (no charge)

Yesterday at the Star performance Dyno Day there was a std internals Sti5 fitted with this turbo (unported) It had a target boost of 1.45 bar across the range in the AVC-R and it held 1.43 from 3600 to 7400 rpm and produced 403 bhp. (that would be 430bhp on some UK rollers) On the low boost setting of 1.2 bar it also holds the boost level throughout the rpm range.
The AVC-R is excellent for boost control as it allows a more aggressive setting in the lower gears to ensure full boost is achieved....even in 1st gear

Andy,

I will chip in, seeing as I know first hand the problems we had with boost control on RObs car.

The actuator, as was, was too weak. Whether it was the combination of downpipe, up-pipe, turbo porting and inlet I don't know, but we had to put so much preload on the actuator, before long it snapped at the weld. Based on that, I would say a stronger actuator, or maybe just a new one that isn't tired, would be a nice thing to have.

As for the 20g wheel, I would say it's about perfect on the 2.5. The garrett wheel is apparently aimed at taking the edge of the surge, whilst also allowing for higher boost (1.8 bar ) in the midrange.

I would also be interested in using another wheel, maybe a 25g, or a large garrett wheel, 57 or 60 trim from the T04E series.

That said, I didn't think there was much wrong with the 20g just as it was.

Paul

Andy.F

Was that on std headers Paul ? I used to run my own 20g at 1.8 bar on std headers and that did indeed require the wastegate tension increasing. However now I'm using tubular headers generally it's the opposite, the w/g needs more area and less tension.

Forgot to mention

I got a TD05 from Grade A Subaru, and assuming it was repairable, the exchange price was £590 (which included next day UK delivery and 12 months guarantee) for a TD05/06 20G Turbo from Andy.F

Cheers

Scoty

Pavlo

Andy,

Yes it was standard ported headers. But I have found that open neck downpipes seem to have trouble with boost, even though you put a nice splitter in the turbine housing.

A nice big actuator with strong spring AND large diaphragm would be the way to go I think. SHould be more stable, and give more scope for control I would have thought.

Thanks,

On my car there seems to be troobly with boostcreep,as i had to port the wastegate on both a VF29 and the TD05,

Does that mean that it will also need to be done on 06/20G?

It´s just a bit strange that on mine the TD05 can only make 1,4bar/3700rpm and the TD05/06-20G can do 1,45/3600rpm....

Is the 1,45/3600rpm with manifold????

Thanks
Skassa

Andy.F

The 1.45 @ 3600 is from the dyno trace and hence not too accurate, it could be +or- 300 rpm from there.
The 20g is more efficient than the 16g and requires lower rpm to produce boost so it is possible to boost earlier in some cases.

This was on HKS headers IIRC

Thanks Andy,

How do all the users thing about lag is it bad???

I must say that i don´t thing that the TD05 is laggy at all,and i don´t thing it would be a problem if there is 300-400rpm in difference in spoolup,

But how is it between gearshift,is it about the same as the TD05 then there is no problem at all.

I have been helping a guy with with a big Garret,and i thing there is a long time before it spoolup to full boost after a gearchange and i don´t want that....

After having the TD05/06 mapped recently I guess you can get loads of feedback from Bob - overall impression from both was that we were well impressed with this Turbo set up. I think for the price no-one can really complain.....

Just a shame it doesnt give about another 50-100bhp...............

Andy.F

Scotty Noooooooooooo you'd better edit that You'll get me shot !

Anyway thats just a substation not a power station

Thanks Andy,

I think i´m just about to be ready for a new turbo


Great Pic.

I have just about sold my TD05,
so Andy do you have them in stock????


Anyone knows about how much a SX FPR is ,as the malpassi i have will not go over 4,5bar !!!!!!

How much can the 550cc injectors go to??

Thanks,
Skassa

Wonder if there wold be enough interest for an SX FPR group buy....

Rob

Denmark

iTrader: (2)

Well i´m ready....


Skassa

Andy.F

How much power or how much pressure ? I have run 550's at 6 bar at full boost without issue although that is not required for 1.4-1.5 bar boost. 550's running 3.2 bar at idle will max out at about the same level as this turbo.
They are in stock, I'll email you info later....I must go do some work now

Andy

iTrader: (2)

The problem with the Malpassi is that if i run 4bar atmo and then run 1,4bar boost it still will not go over 4,5bar on full boost,so that´s a problem.

As it is now my 550cc injectors are around 85% AFR aournd 11,0-11,5
To get 336hp...

So i´m sure i need a new FPR.

Thanks,
Skassa

Pavlo

It sounds like the fuel pump might be running out of juice though.

The way to check, is raise the pressure to the regulator artificially, with a footpump or similar. If there regulator is at fault, then you will see the same pressure difference that you do when trying to run boost.

If the fuel pump is having trouble, it may still cope with the high pressure at idle, which you will see as the fuel pressure rising normally with the pressure you apply on the FPR pressure line.

Thanks,

are there any of You wich had problems with the 255lh walbro pump,and if You did how many miles did it last..

The one i got has about 40k km on it and not more noisy then it has ever been

Thanks,
Skassa

Mr J

Skassa Jerry/SAM had the same problem as you.

SX fpr fixed it though...so not the walbro pump that's the problem

Jan

No probs yet with the Walbro 255 litre pump

I also have the SX Fuel pressure Reg - from Mark A

I think its at about 41psi - or something around that level - but I may be wrong

However I have 740cc injectors - currently only hitting a lowly 83%, compared to about 74% with the VF22 hybrid (but that was without headers)

Lots of room for more fuel flow if I need it
