Another race with GTR and two Turboed 370Z in 4K. Minutes 3:10 and 4:17

 

That satisfaction when youre beating the GT-R , props to you man !
How is the engine so far ? i've read up a lot and most people say 400whp is a safe number for stock block and youre putting down 530whp without nothing done to it ???

 

Everything is good man. If you search the forum you will find people making way more than I am on a stock DE block. It's possible if you do it the right way.

 

Nice Job Staisman...... You are making very nice power and torque.

Have you run the car on a 1/4 dragstrip?

 

Thanks Tim, I did Not tried yet. There is no drag strip in NY, so I would need to go to NJ or PA.

 

Where did you get your car tune may i ask ? Im in NJ and im boosting the car next year so i'd love to know the right people to hook up my car.

 

Vince from RTTuning tuned my car. They are in Pennsylvania.

 

bumping an old thread here...How is the car doing?

 

Still going strong. Didn't do much since then, because I bought a house and priorities shifted

 

Awesome stuff!

 

I bought a new filter with velocity stack in it a year ago and never got a chance to install it. Maybe this Spring, wanna get to 550 whp.

 

This thread is literally my go to thread for my future s/c build! I just wanna see how much you can really get out of the Si trim!

 

I am afraid that's all it can do. If i remove filter and put a velocity ring on the blower I can get another 2 psi. But otherwise I maxed the blower out. If i remember correctly i spin it up to 65K. Next step would be built motor and bigger blower.

 

Can you pulley down to the 2.87 on top of the velocity stack still since u still have the 3.12 right?


You are making great numbers with e85, what kind of ignition timing are you running?

 

I can't, I am already over spinning it by 13K.

I don;t know about timings because I didn't tune it.

 

What is your Pulley Setup?

Get your Timing Specs.... You should know them by Heart.

 

3.12, Fluidumpr, 34, 28

What knowing my timings gonna do for me? I don't even have a cable lol

 

With that pulley combo and 7100 Rev limit, thats 61,100 impeller speed max and that's my pulley setup as well on my SCi. Si trim's max rpm off the site is 52k, 53k for the SCi, so I'm overspinning by about 9k.

13k is alot, how much are you revving out to now if you don't mind me asking?

 

Yes you are right 61099.54. I got my crank pulley size wrong. revving to 7100

 

I'm suprized you are only maing 16psi
