I'd just do this.

Either that, or that Aeromotive 340, I believe?

That wouldn't be enough for 7-800 rwhp.. The 340 is a little deceiving as I'm pretty sure it is not actually a 340lph pump. It is actually a 255lph pump but is a high pressure version. I've got Racetronix's new 340 pump and its great but I'm no where near 7-800 rwhp.

Well, my dream is to build a turbo LQ4. I'm working on getting a damn near complete LQ4 here soon and then very slowly start buying things for it. I'll probably just get the Racetronix kit and call it good for the time being because this turbo build of mine won't see completion for several years.

That's good info to know

The newer Aeromotive and Walbro 340 lph pumps are rated to 340 lph at free flow, just like the older 255 lph pumps are rated to 255 lph at free flow. Don't confuse the older Walbro model number GSS340 with a 340 lph pump, it is only a 255 lph pump.

There are tables out there of pressure vs flow vs voltage if you search around. IE, here is one:

A long time ago people got around the inability of intank pumps to supply enough fuel by running both an intank and an inline pusher. The intank supplied the volume and the pusher supplied the pressure. A 255 intank pump feeding a 255 inline pusher was good for 700+ rwhp back before the invention of the huge capacity and high pressure intank pumps. Now fuel systems have gotten to be so overkill, not many people trust what worked 10-15 years ago.

However, back then in my race car, I ran a Weldon 2015. My street cars all had Walbro 255s and pushers.

I just got done e-mailing two shops in the greater St. Louis area that have dynos. The first place I e-mailed was Craven Performance. I checked out their website, but it doesn't give details on what type of dyno they have (not that it really matters). They'll do $75.00 for 3 pulls. I then e-mailed Mustang Muscle Performance, as they have a DYNOJET dyno and offer the same type of service, but they don't have prices on their website. They do, however, indicate on their website that they are the only shop in Missouri with the DYNOJET Wide Band Air Fuel Monitor, which lets them measure and print on the dyno sheet the air fuel ratio throughout the entire RPM range. I had planned on going to KC for the dyno time, but St. Louis is much closer to where I live. Has anyone used either of these dyno's?

Me. Works great. When Geoff emailed me my dyno sheets I could look at EVERYTHING. All you have to do is go to DynoJet's website and download the free WinPep software.

I'm not following you Dave. Didn't you get your car dyno'd at Geoff's shop, on his dyno?

Lmao $75 for 3 pulls jesusssssss.

I know several shops thatll charge $30 dollars for 3 pulls.

Rise of the Phoenix

That doesn't help me unless they are in Missouri.

Just saying. You have a tuner already in mind? Your just looking for a dyno to rent? Just ask around all the locals. Usually big shops like craven will charge an arm and a leg for anything. Locally IIRC normal going rate was $100-150 first hour and $25-50 after that. I can't remember though. Doesn't have to be a mustang or LSx shop just find a dyno and rent it. If thats what your looking for.


Edit: A simple google search brought up dyno jets in your area.

There is also steigemier performance. He has a dyno jet I believe in St.charles. He ports blowers for mod motor guys. Do you need a tuner?

dr_whigham

iTrader: (49)

Yeah... He has a DynoJet at his shop. Is that what you meant? Maybe I misread the question. I thought you were asking who had ever been on either of those TYPES of dynos, not those specific ones. My bad, lol

Rise of the Phoenix

iTrader: (27)

I don't need a tuner; I have a tuner who has already fully tuned the car. I simply want to strap the car on a dyno, do 3 pulls and get a print-out of the HP/TQ/Air-Fuel.

JakeFusion

iTrader: (7)

Then any shop with a dyno will work for that. Most shops charge closer to $100 for 3 pulls from what I've seen. You only need one pull, maybe two.

Rise of the Phoenix

iTrader: (27)

Yeah, I've got e-mails back from the one place in the STL area; $80 for 3 pulls with print-outs and air/fuel readings. It's the mustang place in St. Louis that has a dynojet. Dirtbag on here suggested Redline Performance in St. Louis; $50.00 for 3 pulls with print-out and air/fuel. Looks like that's who I'll go with.

I meant to go get a baseline dyno of mine here at XXX Motorsports. But oh well. If I come in at 430rwhp, I'll wonder wtf my car was making before. lol

Dynos are heartbreakers I wouldn't get fixated on a number. Shoot if I put down 400whp and smoke a 500whp car, who even cares? Hah

Why aren't you getting it dyno tuned? I know a street tune can be great but it seems like you're leaving some power on the table not tuning it while you're at the dyno.
