As my mom said, "when things take longer than wanted, you have more time looking forward to it, and appreciate it more when its done".

Had her son been half as wise....

I may have some left in a few months... pm me if interested.

Can't wait to see the full system completed and fitted to a car.

Interestingly some the o specialists you may have mentioned in the past have gone very quiet on the turbo front...

Wonder if there is a link

My car has been running for a couple of years with the system, have you seen the pics ?
Not sure who the specialists are you are talking about ?



In other news : I sent out another manifold this week to a guy in the US (is on this site) . Hopefully that one will get fitted fairly quickly and we'll hear how it goes in a few months.
The rest of the first batch are still at the machinist . The second batch has been cast and goes off to the machinist soon also.
Kinda looking like I may end up with a whole heap of them ready all at once

Update : of sorts .
Finally got an ETA from the engineers. Not this coming week but the week after they are scheduled in to be done . Still disappointing from my perspective as these constant delays have taken away much of my initial excitement at the prospect of seeing people get there systems running.
Had a look around several of the engineers in my area to see about getting the second batch done sooner rather than later. The story is the same everywhere ..... orders backed up , staff shortages ...long waits!

Had a good hard drive today and I have to say ..... anyone that gets their system to what mine is doing on stock engine/pumpgas ..........will definitely NOT be disappointed! Local guy in a highly modded EVO X I met recently would be inclined to agree with me.
Tempted to dyno it as is at 10psi ...just as a reference point for those wanting results using a stock engine ...................

That would be great. I have a completely new OEM engine ready for when my current breaks down(111kkm), and I've been back and forward if it should be strengthened. I don't have Renesis expertise engine locally, therefore indecisive.

Also, a 95RON street tune dyno would be excellent, 98 becomes increasingly difficult to source. My thought was that a tune for 95RON street, would be safe on the track, using 98RON. Convenience...

BTW, did you ditch the exhaust porting, or do you still have the small groove that opens quite early? Please excuse my ignorance, I've lost track, I just remember you and Team had a discussion, Team meant you used the end of expansion to spool turbo. Quite possible, but still not a bad idea at first glance, really.

Brettus

That pp exhaust porting you speak of is in my N/A car . The turbo engine is bone stock.
Would not ne dynoing on 95 ...... would be on 98 (E10) as that's what I've run in it for over a year now.

These look great! I'm excited to get started with the build.

looks tasty … glad to see some progress is being made

Should get them physically in my possession day after tomorrow.
One went bananas so might be a reject unfortunately, although I can probably pull my one out and swap it over if I need to.
Should get the first six away early next week but I have some fabricating to do for the remainder.

Brettus

iTrader: (2)

Finally , after 6 months ..... I have them!!!

Its like one last gathering before sending them around the world.

Cannot wait to see these in peoples hands! A huge feat Brett, you should be happy as hell right now XD

Brettus

iTrader: (2)

I'll only be THAT happy when I see others get their 8s running as well as mine!
I went for a drive yesterday with the design engineer (Grant Udy) who did all the 3d modelling/printing and arranged the casting etc. He has a couple of performance cars and is very much into the car mod. scene. It was a wet day so we didn't get to wring its neck but he was super impressed with the response and OEM like drivability.
Which reminds me .... tweaking the throttle maps played a huge part in the drivability equation! This isn't something I normally do in a remote tune but should do with these I think.

excellent work Brettus, happy to see the finished product and can't wait to see these installs getting done.

Brett,
Great job getting this from idea to metal.
Nice to see more development on this engine.
I'm not a turbo guy, but if I was...

Brettus

iTrader: (2)

Cheers Jedi .... I see this more as a starting point than and end point . Some people have a LOT of work to do !

TeamRX8

iTrader: (25)

obviously turbo has some different drivability issues, but I commented on the throttle map subject over the years for NA and it by and large has gone ignored.
.

Brettus

iTrader: (2)

I don't see any issue with the throttle maps for NA use ... although some people prefer it to be more 'snappy' in a race car etc.
For a turbo, few people realise that you don't need much throttle on the stock maps to give you near full power. I see it all the time when people are doing logs for me ....they seem to think that holding throttle back will somehow save their engine from damage. WRONG !
Watch the friggin' boost gage, if it says 10psi at the uim ... you are running 10psi and probably shouldn't be (if on pump gas) !

Brettus

iTrader: (2)

First batch .....GONE !

klikai8

will this fit an S2? I don't see why not...
How is reliability on the track for running the 0.82 and lower boost I'm looking for something like a 280-300WHP max

Brettus

iTrader: (2)

Yes it will fit an S2. As far as on track reliability goes , this is not fully tested at this time.
