How'd dinner go? Any answers?

 

I noticed that My ARIAS pistons were balanced this way . By grinding material off the underside of the piston...just like the pic Gurgen posted

 

Its hard to tell by Gurgen's pic. But the line at the top of the pic.....a straight parellel line to the piston, is the original balancing mark. That is the meaty part of the piston, and the area where a machine shop should be grinding material away.

If you look closely near the center of the piston, there are two driilled area in the center. That is NOT the place where you want to be grinding away material to balance, since it is the thinnest part of the piston.

 

We ended up leaving for dinner right after I started this post so I did not get to ask him these specific questions, but some of them did come up in conversation.

-Current TT kit on G35? No, needs mew piping and wiring to fit the G35
-500-550 at the wheels? Forged internals, APS Tall boy Plenum and 6 auxiliary injectors
-Single Turbo Kit? June 2005

One interesting thing David mentioned was that he spent several hours with a PE owner in California explaining the problem with the common power supply for the CAS and the coils and what APS had done to eliminate this problem. He went on to say what a shame it was that the person had apparently disregarded his advice and has since blown two motors.

This issue really is bringing into question what the stock motor can handle when this problem is fixed using the APS kit, making one or buying one from CJ Motorsports. According to David, the APS car has been running quite a bit more boost with no problems whatsoever, so maybe the 400whp mark is not the safety point that we all once though if this wiring issue is addressed.

It was really quite an experience talking with David about his career in the motorsports industry. He had some great stories and it was as educational as it was enjoyable. I can definitely say that the attention to detail and knowledge APS puts into its products is second to none. For one thing, APS is a vehicle driven company, meaning that they develop many products for specific vehicles. This is quite different than many companies that are product driven companies which tend to know less about the actual vehicles because they make a specific product for many vehicles.

And as for pistons and rods … I did not ask specifically but I think I can say with certainty that APS will not be offering APS rods and pistons. David did tell us who he would use for rods and pistons and neither of them have ever been mentioned on this board. ;-)

 

Apparently there are a few machinists who feel that this is not creating a problem. But then again, there are at least a few that feel that there is not enough room to check the clearance on the oil squirters. I wonder if anyone here has experienced a problem as a reult of balancing at this position on Arias pistons?

 

Yeah David is full of knowledge. Hopefully you guys didn't spend too much on his company card. He owes us some table dances from Vegas and we didn't have time to collect the last time he was here in November

 

I don't think we put much of a dent in that card, just a few pints and good steaks. Lucky for us the table dances around here leave much to be desired ... or maybe thats unlucky for us

 

i'll vouch for david too. i spent nearly fours with him on tues nite in tama. i took ALOT of notes.

he's working diurectly with me and my sr55 issues, and has already made me see "the light" on my mismatch of components.

APS is a great and upcoming company (at least somewhat new to the states). there's so much misinformation afloat these days, its nice to see someone who not only answers questions, but explains the answer (and my question) to explicit detail....

kudos to david and aps. i look forward to my future with their stuff on my sti (sorry to not have Z/G blood here, but wanted to share my experience anyway.

Not the inside of the dome!! ....the flat, slightly curved areas on the 2 risers where the pin boss is. The areas closest to the viewer in the picture.

 

Thanks for sharing esemes. You sti guys are lucky to have had APS working on your cars for so long. I can only imagine what another year or two of 350Z / G35 experience will do for APS and the creative knowledge they bring to the table.

 

Are you going to say what brand pistons and rods he said?

 

Thanks for sharing the info.

FYI Peter has made mention to selling short blocks for the 350z on the forum before.

There is an APS Tech day and BBQ here in Sydney on the 12th Feb, I'll be sure to ask more about this on the day and pass on any info.

 

I have met David of APS and was thoroughly impressed with his knowledge and the company's products. Even though I own the PE kit, which is s very good kit, i admit I would not come close to one if I were buying now given APS' entry into the market. As I have always said.. it's the end-all, period.

 

Precisely!

 

So I imagine the single for the G35 will be around August/September? More time to save up and do it right the first time. btw after two weeks my tilton clutch is toast so I'm going to have to come back by the shop lorca, probably some time next week. I can't take it so I'm switching to the JWT.

 

Thanks for the info. Did he mention anything about when the kit will be ready for the G35?

 

Damen the APS TT system for the G35 should be good to go by May 05 if all of the testing goes to plan, I'll let you know in approx 1 month.

Thanks

Peter

 

Installation and field testing of the APS TT system will start on the 05 model Z at the end of Feb and I suspect the 05 model will only require new computer maps to ensure correct data for engine tuning (best guess only) will keep you updated with more info as it comes to hand.

Thanks

Peter

 

Yeah, I'm glad I waited. All the kits out there have some real good respective points and strengths. What impresses me most about APS is well roundedness. Their kits for our 350Zs seem to have really good engineering present in ALL the major critical areas and for the little things as well.

If I lived in Chicago, I figure Tuan or Charles "Phunk" could make most any of the kits work good for me with customizing and tuning as needed. But I need something more like turn key plug and play with periodic check return trips. I think I have some viable alternatives now with APS.

 

The aps is a good kit but for the money you save on a greddy kit you can make a better fuel setup than the aps and have a programable engine managment system,
More power: charles is the man he did my setup and he has people shipping him zs from everywhere don't let location be a deterent. Thanks james
