I can tell you right now that the 1250 will not cut it. Go here and look at the specs http://www.weldonracing.com/pump3.htmOne Percent said:I'm running a T80 turbo on the car dave - which is how I'm getting so much boost so early - and a huge intercooler.
The car uses a Weldon 1250 pump, 83# inj and UPR rails.
My problem right now is FP - I pulled the filters off the car and they look pretty bad. I'm hoping the filter was just dirty and I don't need to replace the pump.
Mike will teach you the software as he tunes, the best part about Mike is he is always just a phone call away on future problems.One Percent said:I'm contemplating taking the car to Mike - but my overall goal, besides getting the car running right. Is to learn the software backwards and forwards myself.
It is dropping. As the car enters boost my FP goes through the floor. Down to about 20psi - I was told my pump which is a 2015 - not a 1215 - was good to 1000+hp. I pulled the feed filter and its not pretty inside there. I'm hoping that is the root of my problems.Dave King said:I can tell you right now that the 1250 will not cut it.

The 1250 is good for cars making under 500 rwhp.
The 2250 is good for cars making up to 750 rwhp
The 2350 is good for cars making up to 1100 rwhp.
Get a F/P guage on the car and monitor f/p. I bet its dropping.
Your injectors are fine for your turbo application. 83's on turbo applications can be used up to 1300 rwhp. Mihovetz still uses them.
If your still interested send me the program and I can walk you through with it over the phone. I'll be more than glad to help.
Dave if you drag the cursor across the graph white its at WO and right click the highlighted area - it allows you to zoom in on that specific area. Also goes to the botom "dashboard" and double click the areas you dont need - like NOS, UEGO, BPW, Fuel # per hour they will eliminate them from the graph leaving only what you want to look at.Dave King said:The graph is way too hard to read. I took a while before I got a read on it. First thing I noticed very odd is that your pegging the map sensor at 4400 rpms?????? It shows 307 kpa at 4400 rpms. How are you getting that much boost at that low of an RPM?
Thats problems #1
You also need to reduce the run time on your datalogger. For the amount of time your in WOT its very hard to look at the graph. The graph is practically useless the way it is. Remove all those unnecessary parameters (NOS, UEGO, BPW, Fuel # per hour), and reduce the datalog time.
