Aren't 42lbs injectors a tad bit of overkill? I've got a NA 383LT1 making over 460rwhp (traps 126mph) with 42lbs svo's and my max duty cycle is around 65%-70% @7100rpm. I was maxing out my svo 30's and needed to upgrade and got the 42's at a screaming deal, but they are certainly more than I need. And this is at 43psi. Put those 42's on at LS1 fuel pressures and they are effectively even larger. I personally would have gone with a 36lbs but couldn't find a good price. Otherwise your combo looks great!

thanks. i dont think they are overkill after talking with quite a few tuners and sponsors. plus i got a good deal on them through a sponsor off here. i guess if they happen to be overkill, then anything i do in the future, i know injectors wont have to be one of them...

 

Installed a Meizere Electric Water Pump (WP319 in Black), Powerbond U/D Pulley, and Lucas 42lb/hr High Impedence injectors and retune...

HP Tune

Stock 10-bolt/gears...M6

Since most people care to see results comparing apples to apples, I went back to the same shop that installed the FAST 90/90 last August (2007) and retuned the car. These results are off the same dyno. I will let you decide for yourself the gains to be had. Take the difference from the FAST 90/90 or from the dyno day and draw your own conclusion...

First are the results from last years FAST 90/90 install and retune: 444/395



Second, here are the numbers from a dyno day they did last December 2007. Yes the date is incorrect. It's not from 2004. Look at the Run # file. Car is also running PIG RICH...thanks: 437/404



Finally, here are the numbers from the retune today: 458/410






So, it's all in how you want to look at it. The car gained 14rwhp/15rwtq going off the FAST 90/90 when it's know the car was tuned...

OR

The car gained 21rwhp/6rwtq going off the Dyno Day results when that shows the car clearly running RICH...

The old numbers that I used (until now) were from a Dyno Day this past March, but were from a different shop. Those numbers were 443/402 running rich as well...

So again, if you wanted to go off those numbers, the car gained 15rwhp/8rwtq...

I have provided you all with the best information that I can for you to draw your own results as to just how much these parts helped out my car. Apples to apples same dyno used, same shop doing the retune, etc...

Yes I am happy w/the gain in power, but I'm really pleased at how quick the car revs and the fact its stays at a nice cool 172° now...

Personally, I prefer to go with the results from the FAST 90/90 install/retune since I know at the time, the car was running at it's best. Just like this time around, the car today was retuned for optimum performance. So I personally am happy w/an increase of 14rwhp/15rwtq gain...

 

I can post here....so I will.


Graphs look nuts man. For that cam and all the bolt-ons, that car has got to scream. I love those cams. I would have a very similiar set-up if it wasn't for the 402.

Congrats B!!! Get her to the track and update me.

 

What did you do this time...

Graph was even more nuts when the reading was set to RPM and not MPH. no matter where the connection, it was poorly reading the RPMs...

Thanks. There is video. Good sound quality. Car does scream. I will get it posted up tmrw...

 

Nothing. That I am aware of.
It takes me about 10 minutes to post...if I can even get that far.
Oh well...

Congrats again!

 

Your numbers sound excellent bro. Now if you do any trips in this car you will see a nice improvement in gas mileage too. The ud pully, and ewp really reduce parasitic drag. Just be careful going WOT until you get used to how she revs with the new setup.

CONGRATS !!!!!!!!!

 

awesome gains especially with that cam, cant wait to see a vid

 

video is up...

Add the 85 mm lid and maf then due another dyno tune.

 

Why stop there, do a 100mm maf. the id of the 85mm lid is 90mm

 

Great numbers man!
Wait until you get a 9 inch and watch em drop!

 

hahaha, i know...

saving for a 9" w/3.90's as we speak...

 

those are just plain sick numbers for that cam.

if it wasn't for the other dyno graph from a different shop i would have called a little bit of dyno-magic on ya.

but congrats.


i'm excited about installing my Mez WP over thanksgiving. then its to the tuner to see what she's got with stock heads.

 

Hmm, got me thinking about an EWP now. Also, my injectors are at like 87% duty cycle so I should upgrade those soon.
