The a/f is a bit leaner than typical on my tunes due to the fact that the 02 sensor they have here at this shop is reading a bit on the lean side as it is getting old and also due to the fact that this car seemed to be able to tolerate a leaner tune up top due to the reduced back pressure

It really amazed me how knock resistant this car became with limited mods since the last visit - they really had a significant effect

 

Nice numbers

 

Wow...im shocked!

 

I'd like to know what the injector duty is...those babies must be getting maxxed out.

 

with alky and maybe HKS 280's the numbers may be well over 400 WHP

 

Very good numbers!!!!

 

Forgot to mention, my turbine housing is ported as well! And yes I have a Walboro Fuel pump, rest of fuel system is stock. Gas was Sunoco 93. Boost was spiking 25psi, settling and holding 24psi before dropping to 20 around 7000, hence the drop in power, however, it still makes around 350whp at 7300 which is still good!

 

25 psi on 93 pump and no knock?

 

it goes to 25 for a split second and actully 24psi on my boost guage is 23.5 or something, Im getting a new one to read it more accurately. ive been running 22psi my first dyno and got no knock whatsoever

 

Absolutely astonishing Bro. Congrats big time, you impressed me. Great tunning from Al also. If you made so much power from your current mods without alcohol, I don't even want to think how much power and torque you could make with the Alky kit.

Definately you answered my questions about the next mods, I already ordered the DC manifold 3 days ago, I was going to order the Works o2 housing and last but not least I am waiting to order a bigger intercooler, I am just on hold to see the Buschur Dyno results vs Nisei.

Definately give me a couple of weeks and I will also post the results from my upgrades(same upgrades you added), I love when people share their experiences..

Nice numbers. No cam gears with those 272's?

 

What are your air fuel ratios?

 

Anytime man! Glad I could help you out!

Stock cam gears.
They are on the bottom of the dyno sheet... they range from 11.5 to 11.9 at around 7000.

 

Tom I guess once I get my stuff installed and tuned we can compare numbers...

I'm also looking into doing my clutch at the same time....thinking of the ACT clutch with the X-Treme PP and sprung street disc

 

I actually had the ACT in my room waiting to go in but after all the horror stories about high RPM shifting I sold it.

I plan on getting an RPS single-disc, there is a couple guys running this clutch (its around same price of ACT) and nothing but good reviews from it. Plus, its not like RPS isnt a reputable company!
