New numbers...2.3 Whipple maxxed...2.9 time

[03termy]

Just converted my '03 Terminator to e85 a couple of weeks ago.

Old 93 octane pump gas numbers on the 2.3 Whipple were pretty impressive (I thought so anyway...) 731hp/732tq @ 13psi

New numbers are 789rwhp/772tq. That's with the 3.0 upper pulley.

We swapped over to the 2.75" upper and got some better numbers (816rwhp/809tq) BUT got some belt slippage. So, under advice of my tuner, we put the 3.0" upper back on the car to have less drama on the street and keep the car super-reliable. Its driven on nice weather days back and forth to the gym with ZERO issues.

Thinking it's 2.9 Whipple time because he says I have plenty of fuel left and motor is built to handle it.

Congrats! If your able to spin the 2.9 with the E85 thats def the way to go..

Damn good numbers, congrats. 2.9 would be wicked if you can spin it. Wish I would of went through with installing the 2.9 crusher on my car.

789 out of a 2.3 is very impressive. The 2.9 set up will be a beast

Nice numbers

 

[ctgreddy]

great numbers but im crazy impressed with your old numbers on 93 octane! if you're content with ~800whp just send the 2.75 to a machine shop and have them cut the anti slip grooves in it. It does help.

 

[gabe1530]

what compression are you running? i could see you getting very close and even breaking the 900rwhp mark with the 2.9.

What's the compression?

 

[azc0bra]

Good numbers... I'd be curious to see how it does at the track.

 

[PWORLDSTANG]

What size pulley were you running when you saw 13psi and 731rwhp/732 rwtq?

 

[Brutal Metal]

How the hell did it make that much power on 93 with only 13lbs?

That 900 mark is my goal. Tuner thinks its def coming after the swap....

What's the compression?

9:1

Good numbers... I'd be curious to see how it does at the track.

@731 hp on 93...PLUS my first time at the track in the car last October, it ran a 10.90 @ 135 (1.79 60' on ET Streets) on my 2nd pass ever in the car. Still tweaking my launch techniques.

What size pulley were you running when you saw 13psi and 731rwhp/732 rwtq?

3"...but it actually peaked at 13psi. The car holds 11-12psi according to the boost gauge.

How the hell did it make that much power on 93 with only 13lbs?

9:1 compression...5.3 MMR build...good tuner. :thumbsup:

Trust me...they aren't inflated numbers. I have been beating/running with cars people say there's no way possible with a 2.3 Whipple. Plenty of people have witnessed it firsthand.

very cool. im looking forward to your results.
sounds like your combo is pretty efficient and has lost ~ 4lbs of boost pressure compared to a normal oem longblock w/ a 2.3l.
with a 2.9l crusher, i would go strait to a 3.0 upper and see how much boost your at. it should be around 20/21lbs. with a stock engine, it might be around 24ish lbs. anything below the 3.0 and you might be fighting belt slip again (depending on the type of pulley used).

any reason why for 100.00 more you don't go with a 3.4?

Thanks for the info....I think I'll stick with the 3.0" upper. Btw, I didn't buy the Crusher...standard 2.9.

I like my stock hood.

3.4 fits under the stock hood. I have a 2.9 whipple and its a bad ass blower. Im tempted to try the 3.2 kb mammoth for our cars.

What kind of hp/tq are you seeing out of the 2.9 Whipple? I didn't want my torque curve to suffer going from the 2.3 to the 2.9. I'm making 740 tq @ 3250rpm.

 

[stangfreak]

well im on stock motor and running 22lbs of boost. Im seeing 650rwtq. My car is also a under achiever. Its a soft motor. I also had a 2.3 whipple at 23lbs stock motor. yes you do have to spin the bigger blowers a bit more, but my 2.9 was MORE violent with one lb of boost less than the smaller 2.3. I was amazed. The 2.9 is a bad ass blower. Built motor and e85 it will be sick. Your extra cubic inches could use that little bigger blower. I love my 2.9
