Which high flow fuel pump should I get?

[cdssolara]

Can you guys let me know what year they switched from the old style fuel sytem to the newer returnless fuel system?

Gadget

Gadget,

From what I can see, Toyota switched to the returnless system in '97. The first Solara model year was '99. I'm not sure what year the Gen 4 Camry came into existence, but that is the generation that corresponds with the 1st generation Solara. Assuming that it was before '97, there may be some Camrys with the 1MZFE engine that have returnless fuel systems.

Does this mean that the EBC is taken off (because the EBC won't open the bypass valve till about 3k)? If so, how do we protect against rev limit boost concerns? Just curious and very interested in your kit.

This is a postive displacement supercharger and not one of those centrifugal superchargers that keep increasing in boost as the RPMs build. The boost on this supercharger is real close to the same at all RPMs.

This is not a concern with this type of supercharger. The only concern is the auto tranny and you absolutely will need to have the valve body upgrade to run our upgrade kit on it. If you do not, you will break it. The performance increase is that substantial.

Gadget,

Are your trucks manual or automatic transmission? The EBC seems to have been a problem mostly for auto trannies in that it cuts boost in first gear. That has never been a problem for cars with manual transmissions. When my car had the stock pulley, I never noticed boost below 3k-3500 rpm. However, once I went to a 5.5 psi pulley, and later to a 7 psi pulley, it seems boost kicks in much sooner. Therefore, I wonder about the lack of boost below 3500 that you're talking about. Maybe it's just the difference between the supercharger you've been working with and the one on our cars?

I am very interested in your kit, and I give you a lot of credit for the research that you've done and for the fact that you're trying to expand to our platform. I've read through your website several times and have learned a lot from your experience. However, I think that it would be good for everyone here to see dyno charts (for our application) before they start committing to this product. Based on what I've heard so far, especially from JoeB, it seems that this kit can make a real difference. However, the same thing happened to some of us last year regarding lower compression heads. A few of us, myself included, bought the heads based on a couple of testimonials but without seeing dyno results. While the heads did have some benefit, I don't think they did what they were advertised to do, and I don't think my money was well spent. Based on that experience, I know I won't be buying anything else for this platform without seeing dyno results. I'm not being skeptical of your results, especially since I've read about your experiences. I'm simply playing devil's advocate.

I think you have a good plan of action. There is so much more that goes on that a WOT dyno run on a DynoJet will not show at all. I think Joe will tell you how much more responsive and how much more torque he has now at part throttle.

When I first drove his car I flat did not like the way it drove at all. I am used to both of my supercharged 4Runners, one with a manual and one with an auto, feel when they are driven. Boost is instant at any RPM, none of this wait until you get to 3400 RPM and wham, it goes. It just felt slow and sluggish until you hit 3400 RPM. It is not slow and sluggish anymore!

I think that everyone that does this will really enjoy how much more fun the car is to drive.

The main purpose of the EBC was to cut boost in between shifts to protect the auto tranny. Also it has boost cut after red line.

The lack of boost in first gear on an auto is argueable. I have boost with a properly hooked up EBC, while others do not.

From what I saw on Joe's car is that you can have full boost in any gear, just not below 3400 RPM.

cdssolara, I intend to run it on the dyno AFTER I get the tranny upgraded at Level-10. I don't want to do any damage just for a dyno. I'm getting the tranny done the last 3 days of this year. I will try to get the dyno done as soon after as the shop will take me in. I'll post the results here. I don't know if the total hp will be that much more but I'm guessing that the curve will look different. Normal drivability has been improved dramatically. Now when I'm driving and kick the gas I feel an immediate surge. Before, it was kind of soft until it got up to about 3600 RPM then the supercharger kicked in and it would TAKE OFF. -JoeB

Were you able to get the tranny work done? I'm curious about how effective it is, as I'm considering having the same thing done on our G35 sedan.

Gadget, I have a SC 99SLE (auto) and have Apex S-AFC installed. If I want to use your udprage will it work with the Apex S-AFC, or will I have to switch to the split second unit?

Nick

[cdssolara]

In order to do the adjustments that he feels are necessary, you will have to use the Split Second unit. Based on his earlier posts, and from what he says on his website, adjusting the timing is just as important as adjusting the fuel. The S-AFC units do not adjust timing, but the Split Second unit does.

That's what I thought, I think I am just going to leave my car alone. I'm pretty happy with it where it is. Every time I put my car on a dyno something seems to break.

Nick, I should just wait for Gadget to reply because I'm sure he can offer good advice there. You don't have to tune the car on a dyno and Gadget didn't. As a matter of fact, you're right, dynos ARE hard on a car and that is not the normal way to tune it. Gadget has a good base map for your car by doing my 99 SLE. I can't believe how good my car is running now!

I just drove it 250 miles and dropped it off with Level 10 in NJ to get the transmission valve bodies recalibrated and the high stall torque converter. Gadget asked me not to get on it off the line until I got that done because of all the extra power in 1rst. I filled up my car at 435 miles on the way home and used 14.888 Gallons of gas. 29.2 MPG! That is WAY better than what I was getting. During that trip I had several opportunities to punch it to blow past annoying traffic and have a little fun, about 130 miles of driving ~35-45 MPH through small towns (stop and go), 1 traffic jam on the highway for 40 mins and the rest was smooth highway driving, a good mix. Un-Freakin-Believable! The last time I checked my gas mileage, it was 23 MPG a long time ago. Frankly, I really don't care about my gas mileage, it just seemed to show how well the car was running. Now that the transmission is done, she's SMOKIN!. I'm going to take my car back in for another dyno run as soon as they will take me in. -JoeB

Sounds really great, Joe. Can't wait to hear more about it as you get a chance to really test it out. I'm also really curious to hear about what happens on the dyno. Keep us posted!

Gadget,

Thanks for getting this out so quickly. I'm interested in your product, but I want to see JoeB's dyno results.

Also, I have a question regarding my particular situation. I have non-stock cylinder heads on my car that reduce the compression ratio to around 9.3:1, versus the stock 10.5:1. The main reason that I had these installed was to be able to safely run higher boost using the 91 octane gas that we call premium. I'm wondering whether the fuel and timing map that you have programmed into the SS unit will need to be adjusted for my lower compression.
