Pudsey Posted April 6, 2011 Share Posted April 6, 2011 Looks great seeing two big twins on a VVT-i, your certainly doing a great job. One question though..... looking at the pictures just out of interest really. It looks like there is alot of weight hanging off the side of the head, and I would imagine it will get very very hot there too. I guess it shouldn't be any different to the standard twin turbo set up, but it just looks like its all further away from the bolting points. Whats your thoughts about the extra stress, this may cause? (NB: If it is actually heavier than the standard set up of course). Link to comment Share on other sites More sharing options...
hodge Posted April 6, 2011 Author Share Posted April 6, 2011 soooooo jealous! nice work hodgemeistro Think I'm looking forward to seeing it with the head bolted on more that Johnny is lol. Link to comment Share on other sites More sharing options...

Whats your thoughts about the extra stress, this may cause? (NB: If it is actually heavier than the standard set up of course). It's a lot heavier. I lifted the head and turbos off together by myself when I stripped it down, it's a huge strain for 2 of us lifting this into place. It is going to get VERY hot in the engine bay, your right there hence all the heat wrap. I'm also going to be making a couple of heatshields for the turbos and another for the brake and clutch servos just to protect it and stop the fluids boiling. Oh and the sound deadening is going from the under side of the bonnet, but Johnny doesn't know that you haha. Link to comment Share on other sites More sharing options...
hodge Posted April 6, 2011 Author Share Posted April 6, 2011 Just as a point of interest there is no way on earth this job could have been done without either removing the head or the engine. I was very surprised when lee told me I'd be best pulling the engine to fit it but I know where he's coming from now. It's ridiculous how tight the fitment is.

I knew it looked heavy, but from what you have just said it must be very very heavy. Great to see the old boundaries being pushed though, Johnny's a brave man taking this on. Great work so far!!

johnny g Posted April 6, 2011 Share Posted April 6, 2011 Johnny's a brave man taking this on. Thanks mate It's a little different doing the twins - and the VVTi; but I'm more interested/concerned/apprehensive about how the new DBW throttle arrangement will work, it's from a Corvette Z06 (pedal and TB), so it's all very modern, very new. All parts were purchased new for it - so it's a case of seeing how it goes. Link to comment Share on other sites More sharing options...

Can't see any reason why they won't work, as long as the sensor signal can be read by your management system (and they are all practically the same thing aren't they 0 to 5 volts). I think you will need a neck brace everytime you drive the car once its up and running, as your neck is going to be under a fair amount of pressure when those bad boys spin up. Great times.

Once it's all together Johnny and I get the oil and water lines we'll have to measure up for some thermosleeve. I'm under no illusion that whatever isn't heat insulated is going to melt or pop.

Yea, the Syvecs can do the DBW no issues. The main issue is the characterisation of the TB and the Pedal. I've skimmed the information from the MoTeC site, so that the Syvecs guys can build a calibration for the throttle body. The next item is the selection of the throttle map and the curve I want to run - that's proving to be VERY interesting reading. Link to comment Share on other sites More sharing options...

Yes mate, that's part of the reason I never went Syvecs with the stock DBW before hand with BPU/TTC - and I didn't want to retrograde to cable throttle. So, I've got a 2010 TB and pedal assembly - let's see what it can do. Link to comment Share on other sites More sharing options...

johnny g Posted April 7, 2011 Share Posted April 7, 2011 Whats the benefit of going DBW? Main one is to be a bit different for me really, but from what I've read/seen DBW systems can also react rapidly to changes in the aim throttle position. DBW can do throttle blipping on down change, more controlled launch and traction control and elimates the need for a idle control valve and retain a good idle/cold start. I also like the idea of mapping the throttle input relationship to the opening of the butterfly. Lazy pedal or sensitive pedal - just select the map Link to comment Share on other sites More sharing options...

hodge Posted April 7, 2011 Author Share Posted April 7, 2011 This is quite ironic really as I text Johnny a few hours ago telling him to get a new alternator cos his was about goosed. Ok guys, head is on, all plenum wiring is done, fuel rail is plummed in, cams are in but need to be torques down. Tomorrow I'll finish off the cams and get it timed up, fit some covers etc etc. The only issue I've ran into so far is the oil feed for the rear turbo. I've got a fitting directly into the block but the wastegate is about 10mm from the fitting so there's no way I can get an AN female over the top of it. I think I'm going to have to remove the fitting from the block and try and get a banjo to fit. If not then I'm going to have to take the oil feed from turbo 1 and "T" off it to turbo 2. I'll look at this at a later date though, as I want to get as much of the front of the engine assembled as I can. And I've a small hole to cut in the chassis for the motor for the TB to fit through so it doesn't foul. I'll stick some pics up tomorrow of the progress. It's starting to take shape now though. I'm going to get the turbo housings and a couple of other bits sent off to Rob tomorrow for polishing too. Link to comment Share on other sites More sharing options...

hodge Posted April 8, 2011 Author Share Posted April 8, 2011 (edited) I was going to wait until Johnny had been up on Saturday before I posted pics up but seems he can't make it this week here you go. All intake wiring is nicely tucked away. Powdercoated PAS tank. I'll post some more later after I start the build up.
