AZ, I dunno. I need to find the sheet of info from NASA I read that from.
I overlooked the GPH/LPH, qckser. I knew what you meant. My old 91 SE-R has a 300TT pump, plenty for the 100 shot or the GTI-R swap starting this weekend, and plenty for a Q 100 shot (per JWT) therefore a 6psi Q. We already have the purple 370cc injectors.
If it's produced so that the manifold can accomodate a core in it's housing, therefore making aftercooling optional, that's a win-win for everyone & will broaden the market base for any fence riders or future customers.
Gentlemen, we've done the impossible (Q45 supercharger group buy!!)
That would be nice. Maybe HeavyDuty would head this up.dkill wrote:This is getting to confusing for me...I dunno what to do now... to bad agm isn't heading our project :P
My concern is I don't want to see anyone's Q destroyed because some detail was missed. Has anyone mentioned what type of sparkplugs that will have to be used after the Q is s/c? What will happen when it's 95 degrees outside and heat soaking becomes a factor? What about the blow off valve?
I would definitely listen to AGM's suggestions and I would call aaacomp aka Glenn. As I said before, he knows alot about enhancing the performance of the Q without compromising reliability.
Just some things to think about.

I was trying to be helpful without stomping on his post/desire to see this through. You're right, there's a lot of considerations and a Ready, Fire, Aim! approach could be disastrous. dkill is to be commended for his initiative & willingness to see it through. I hope at no time have any of my comments been construed as counter-productive, it's just that I hate to see people make costly mistakes, even if that cost is just disappointment and nothing else.QShip wrote:That would be nice.

Destruction is a possibility without a power adder, but more critical when using one. Plugs on a 6psi kit would be ok with the same heat range, but preferably Irids (non plat tipped irids) or copper core, definately no platinum or double platinum, although some manufacturers (Ford, for instance in the new Lightning & probably 03> Cobras) are using plats in s/c applications with low boost for emissions reasons. A plug is an emissions control device, BTW.QShip wrote:My concern is I don't want to see anyone's Q destroyed because some detail was missed.

The intercooler provides for a ~40 hp gain over the same boost level non aftercooled. They remove up to 100 degrees from the intake charge. If you use a JWT boost program, it will make whatever corrections necessary to deal with changing conditions. However, as I mentoned before, a non ECU or rather stock ECU with FMU setup will require more fiddling as the seasons change. Winter tune / Summer tune.
A blow-off or recirculation valve should be integrated into the manifold so that when in vacuum (cruising) it doesn't boost the motor constantly. I'm sure this has already been addressed in the BAD kit by Mr. Knight, but that's why I wanted to see the setup AZ was talking about before I expressed any interest in the setup personally.
Besides the BIG stuff, the little stuff is of concern, too. Annoying stuff like belt tensioning, or hopefully lack thereof in constant adjustments. Good tensioners, materials that can withstand being installed/removed many times. I've seen and installed kits from *just about* all of the big boys & even theirs lack somewhat in execution & particularly in the installation drawings/diagrams, it's obvious they wrote the manual for installation with the engine OUT OF THE CAR!
Also, FWIW, I've not heard of any manufacturing differences on the kits between the 90-95 years insofar as Base, Active, or Touring differences, architectural differences on models with TCS, etc.

Don't ask AGM, he's running a centrifugal.
Just kidding, of course. Turns on a little slow, but comes on like a freight train or hand of God pressing you into the seat further & further. An Eaton is good for BLAM! out of the hole boost, which can be a more stressful on driveline components than a centrifugal that lets the car get underway before gradually letting loose. An Eaton probably also generates more heat at higher rpms. Any time you compress (air, in this case) it's going to get hot. The centrifugal gets hot, too, don't get me wrong. I probably should have kept my mouth shut on that last paragraph. But on the positive side (pardon the pun) an Eaton has proven to require far less frequent rebuild intervals and is MUCH quieter than a Paxton/Vortech (now the same company but different units) and Lord knows an ATI, needless to mention Powerdyne, etc. I know most of you wouldn't be OK with +/- 2 year rebuild intervals (for a daily driver) on even the best Centrifugal from a cost/downtime standpoint. Also, the lack of oil supply & drain required for *most* centrifugals makes a unit like the Eaton more desireable from an installation standpoint -vs- turbo, Vortech, Paxton. The ATI & Powerdyne, among others, are self contained lubricated.
I'm rambling again, sorry to all, but I would hate to see enthusiasm surpass thoughtful, thorough, common sense in concept and execution.
AZ, dkill, if I can be of any assistance, please let me know. If you'd like me to keep my comments to myself, that's OK, too.
No hard feelings. :pface
Regarding, to intercool or not, I offer the following advice.You can probably get away without intercooling at 6psi without any problems. What happens though, is that you start off at 6psi and have a really big smile on your face, but you get use to 6psi and want more.
Without allowing for possible intercooling now, you are stuck at 6psi. It may cost a little to allow for it in the base design now, but it will save you big bucks in the long run, if you are tempted to put on a smaller pulley and go for mor psi later on. It costs so much more to redo it later on.
An intercooler is probably more important for an Eaton than an Autorotor, because the the Eaton scavanges air from the intake manifold. ie it recirculates hot air from the engine due to the lobe design. Eatons are great for low down power, but peter out a bit at the top end.
There are pros and cons for any Supercharger type/brand. Before commiting to an Eaton, check out the specs on a Opcon Autorotor (Stefan is VERY helpful) as you might find that the deck height is lower than an Eaton and will fit under the bonnet easier with a charge cooler.

dkill,
I hope I am not running you around in circles, and am actually being of some help to you, rather than just confusing.
In summary, my recommendation is based on being able to intercool and NOT touch the bonnet. To do that will be more expensive and complicated.
Whilst, I still would PERSONALLY, go down the track I mentioned before, I think that the most cost effective and simple track that is likley to suit yourself and other NICO members, based on my understanding of what has been expressed on this forum is to follow Geoff Knights recommendations.
A lot can be said for Geoff already having experiance with the Eaton on a Q45. Rather than start over again, there is comfort in sticking with the track gone down before.
Stick with the Eaton, as it will be OK non intercooled up to 6psi and fit under the bonnet.
If you go for 6psi + or are not bothered about touching the bonnet go for the type of intercooler that Geoff is talking about.
The type of intercooler Geoff is talking about is quite often used in Marine Supercharging applications. It is a seperate piece that can be added later.
For an expensive example see

The SC draws little power to run while in vacuum (cruising). The biggest difference will be modulated by your foot.
$3500 for kit$500 for ECU reprogramming$600-$800 for the items necessary to complete the aftercooler system (if desired, optional)$60 for a good trans cooler$150 for gauges, (1) boost, (2) air/fuel or egt, one per bank. They are a good tool if installed properly, if nothing else than an "OH $HIT!" gauge in the event of a fuel system failure under boost. The boost gauge would advise you if the S/C belt was loose. (reduced boost level).$500-$1000 for installation of the above, depending on aftercooled/not, trans cooler/not, etc.$25-$60 for non-plat plugs.Even at 6psi, I would consider sending a core set of injectors to RCEng.com for cleaning & flow matching.
Yes, dkill, the core in the manifold mentioned my Mr. Knight is the aftercooler core myself & AGM & everyone else is speaking of.

Q45Racing down but not out
hi folks its me freddy b...in the middle of a new host and server so Q45Racing.com is down but not out...recently moved to orlando florida, and I'm willing to go check out this BAD Q today if anyone will let me know where i can find it..... I was offered $3500. to supercharge my Q when i was in california, but hey had a job transfer and here in orlando... and this place the racing scene is real hopping....... I would be interested my self in a SC but I'd like to see a turbo Q, i know they have them in japan and i'm trying to get a hold of them my email but trying to write japan is hard even with a japanese translator program...
well just a quick note. to let everyone know i'm still alive, just got my new internet now since jan 30...man its a bummer without the net....
email me if ya need anything you know i can get stuff at wholesale prices.....otherwise cheap and i work from home so overhead is low.....
about the bodykits on my site.... once again there are all avail from me. but the cost seems to drive most people away... but remember only japan has the real kits.... so they are all special order items.... uncancellable i will update new pricing on the new site which will include shipping but as always can change due to the yen rate....
if my old server hasnt knock down the old site here's the urlhttp://q45racing.bizland.com

There is a drop in Solution for the Y33....Its the VQ30DET. I found a full front clip with the newer 5 speed auto...Probably not an easy swap ill bet. Mechanically it would be a sinch but getting all the electronics mated together could prove to be daunting. And besides a Twin or bib single VH would be a monster:).

LOL - Trust me, I've earned it.
Actually, the only thing that will save me is the cost of the case. The internals will need to be gone through, and all the other stuff will need completing. I'm still in.
Kevin Camp (the CA guy) is in as well.

A little too expensive for me at this time. How about an electric one.

Dkill, sorry but I'm out. I have not heard from Tony for a while, but last we talked we were inclined against the buy. I considered investing in the development for a future use. Then I decided to seriously explore a second project car. The direction on that vehicle will be drastically different, and will require considerable cash. So, this buy is out.
:surprisea Not for a while. I like traveling different roads, hence a Q on track. I know that I will approach this project differently then how I did the MAGCQUE. I plan to remove everything, including all wiring. I will start with the frame and skin, and go from there. My difficulty now if my being in Afghanistan. I have identified the vehicle that I want to use. I have to get it transported and disassembled. Major work for sure. Maybe a year or more just to get it stripped.
I had hoped to be in the states all summer. I had planned to spend a lot of time on track and would have allow great progress on the new efforts. But it seems that I am often too successful, as it now appears I will spend most of the next year here. Good news is that the much higher pay will allow me to afford the new project car. In my absence I have had built a new deck that is huge, and I plan to build a project garage under it. The garage will accommodate 2 – 3 vehicles and I intend to have a lift installed.
Dreams. I just need time to enjoy them.:wavey :wiggle
