With the EFR turbo off my SSTC for product development, I wanted to try out the S259 turbo I had at the shop. I bolted it up yesterday as a standard ZZP LNF turbo upgrade kit. All of the parts are off-the-shelf and available through ZZP with the exception of the larger turbo which we could substitute in as well as our MAF based fueler and the secondary set of injectors which we are getting ready to finalize and put together a kit. I started out with factory boost control, but it is difficult to get accurate, consistent boost control above 30psi boost, so I switched to our manual boost control regulator. This car is running on our 90% ethanol fuel that we ran in Ryan's LSJ. Tonight, I decided to do a few dyno pulls. Here was the best pull:



It appears that we are finally running out of in-tank pump. The fuel pressure was dropping towards the end of the pull despite the mechanical pump increasing speed. That is a sign that the feed pump just can't keep up anymore. Either way, I'm not complaining. This pull was 598whp uncorrected on 90% ethanol running the stock in-tank pump!

 

lol jesus. you guys are nuts. way to go!

 

Awesome stuff.

 

so when are you gonna run some 10's in that beast Us LNF's need some representation

 

Nice!

 

What's the dyno look like if you start at 1500-2000 rpm, instead of 3750 rpm?

Or, do you just set the idle at 3750 and drive it like that?

Dog

 

This. Awesome work

 

Wow very nice numbers!!

 

wow thats big power did you drive the car at all or just dyno it

 

Hell yeah zzp ftw!!!!! I love the ***** you guys have in trying all this crazy stuff!!!! Keep up the great work!

 

Any idea when you can do pump instead of ethanol . pleaseeeeee


600 whp with e90 on stock fueling is no ******* joke!
wait, second set of injectors huh.. how much is stock fueling?

 

The secondary injectors are what I'm interested in for sure. Need to figure out what needs to happen for that... and your stage 2 trans that you are coming out with.

 

In the words of Shaggy, Zoinks!

 

Hoping to make you the same way as us. Just let us take the LSJ with us after CED and you can fly home! Need to add more 500+whp cobalts to the stable.

 

Well, see we tried setting the idle at 3750, but it didn't help me win any races. Every time I shifted into 5th gear, the car was going over 100mph by itself! I couldn't find too many people that wanted to go from a 120 roll. What really sucked was when my car wasn't running this one time when I tried to race someone. I had to start the car and then floor it, which wasted a lot of time. But even worse yet, this one time I got in a race with this kid in a Civic. I would have beat him, except I wasn't in my car. He got a huge jump on me while I was looking for my keys, then i had to run to my car, get in, start it, and then wait until it got up to 3750 RPM. He was WAY ahead by this time. It took me a while to catch up!

 

Hahahahah

 

you have no idea how tempting that is. give me free labor and lets make it happen with a built block

 

yumyum

 

And the award for best fabricated short story goes toooo....

 

That's awesome

Impressive, I'll hopefully be close to there soon

 

so can we please get some pump numbers for the ppl that are less fortunate that cannot run ethanol. this is the second time i'm asking. and on other threads you skip my questions.

 

What are you asking?

 

You guys keep impressing me! When can I come pick up my new parts?

 

Not bad lol. I hope to run over 500 with race gas. Matt I know it's short notice but Norwalk opens Saturday. You guys should come down. I won't be running but will be there.

 

Need another lsj for testing? take mine lol

Great work though, some serious power.
