Dan's R32 - more fun than a barrel of Aventadors

[felix yuen]

Keep up te good work
I m glad to see this project getting close to finish !!

Already sold! Sorry.
It'll be worth the wait.

Thanks anyways. I ordered mine yesterday through cam with a AIM Dash Hopefully I don't regret it and want the V88 :S I figure the ECU should hold its value decently especially when the USA starts getting R32's in.

Nice build BTW. I'm thinking of adding an accusump myself!

[GTR-Dad]

Accusump, is it controlled by the ecu so it's only in use at higher driving loads ( I think the EPC valves could remain open at idle due to the low pressure)

Not 100% sure, but I think it's set up with ignition only. If it partially discharges as idle, it'll charge back up as soon as oil pressure climbs, so simpler works fine.

Knock control: the knock box was $700, going to a v88 was cheaper (over staying with the v44)? I thought about doing this for similar reasons (multichannel AFR and EGT) but decided not to since I drew my line at street car, now I wonder if I should have gone to a v88 with all the gizmos I have... Do you have pictures of the manifolds?

I the V88 was a bit more money, but it did what I wanted. I'll look for manifold pix. It was NOT easy to drill and tap for 6 EGT probes.

How was the watermeth (assuming aquamist) plumbed in? Under the plenum?
Having a drysump is the ultimate oiling solution (which I regret not doing since I nearly spent as much on a wet setup with 13L but no protection like a drysump. What did you do to solve the fuel starvation in the Gs? Going fuel cell or bandaid swirl pot?

The injection pump and reservoir are in the trunk and the lines go in from the top of the ITB's, upstream of the butterfly valves. Fueling is still the OEM tank as I didn't want to give up range. A swirl pot would be a good idea, but for now I'm just keeping the level high. No problems up 'til now keeping it above about 1/4 tank.

Did going with a water meth setup (safety only or power adder also?) allow you to get out of the lowwww power robbing AFRs? How high will you be going? As good as the clean 12.5 area? I'm still on the drawing board so I'm always changing stuff...

525 awhp is pretty savage for the driving I do, so I'm not too concerned about adding power. (Ask me again in a year... ) The main decision driver was the ability to run more timing at lower boost to make the same power. Or more timing at the same boost to make more power.

Is thereaftern Alberta shop that can get the tomei exhaust? I'll have to hear a good video/sound clip to see if it sounds good, I'm sick of hearing the gutless nismo or kakimoto...

Cam can get the Tomei exhaust. Daryl is looking into having mine drop shipped.

Do you know if there was much to be changed with the V88 install?

The V88 is a bigger unit and will NOT fit in the OEM location. There's an auxiliary board that crosses over from the OEM wiring harness to the V88, which takes up more space. It comes as a bare circuit board, so Lightspeed built a pro-looking box to keep everything clean and protected.

Cheers,
Dan

Thx! Was not trying to challenge the current GTRC record holder for longest build.

Good idea for filling short term needs. You'd be amazed how much flow goes through the oil system.

[leeaspin]

Is the accusump system a waste of money if your not going to track the car? Curious about the system....

Also looks really clean sir. Just wondering about that oil pot you have located in the trunk. Is it touching the floor of the trunk? With the weight of oil in there I dont know how well that bracket will hold while your beatin around a track. Just doesnt look like enough support to me and i've seen plenty of aluminum welds peel apart!

The accusump provides oil at startup (primary benefit IMO) and a second or three of oil supply in the event that the oil pickup sucks air. Having said that oil supply at startup is the primary benefit, I don't know of many engines that wore out because of the lack of oil at startup. I prbly added it as an insurance policy more than anything else...

Thanks for the warning on the reservoir bracket. I'll take a good look at it before and after some high G loading and make sure it's up for the task.

Thanks for the input.

Dan, since summer is almost here and I'm still on blocks, I might opt to go with a V88 but I'm curious to know where I'd install the bungs for the multi-wideband sensors and multiple knock sensors... anychance you have pictures of where those are installed? You can PM if it's not for the public eye. Don't worry about intimidation, I'll never be faster than you

Ha ha! I enjoy hanging with faster drivers!

The indiviual cylinder knock control uses only the OEM sensors and knowledge of which cylinder just fired. Real time fuel trim is based on EGT, not wideband data. It's pretty tight to drill and tap the exhaust mani, but can be done. I swapped out the OEM for a Tomei extreme exhaust manifold...
The fuel trim is really just a safety to cool things down a bit if the water/meth isn't up to the task.

[Dakota_gsx]

Saw your car today when i was at lightspeed and holy F. looking very nice Dan! that oil tank in the back is friggin huge haha. Cam was telling me about the extensiveness of monitoring you have set your car up for to improve racing. I just wanna say good job! Picked up my engine today so ill hopefully have it on the road by the end of the week!

Hmm. I'll have to see if I can sell my knockbox kit.. Didn't know I'd need OEM sensors again! As for drilling being tight, I'll make take my tomei manis to LS then, though they are 5 years old they're still like new and don't wanna screw up/replace them.

I'm eager to improve my game and there's nothing like measuring what you did on the track to tell you where you can improve!

Hey Dan, any results from the different valve size?

[GTR-Dad]

Still resolving a top end niggle. There's a heavy tick that we think is coming from a sticky valve or bucket. The head is back off and the search is on. No break in miles yet.
