Hey..

This is my setup...

1991 CRX Si
B16A1
10.6:1 CR (.030" Off the head)
Crower Stage IIa Cams
Ti Retainers and Dual Springs
Adjustable Timming Gears
Walbro 255 LPH Fuel Pump
Custom Chip with Vtec at 5700 rpm
fuel pressure at 50 PSI (A/F Is roughtly 12.8 the hole pull)
4-1 Headers into 2.5" Open exhaust
Skunk2 Intake, 68mm TB, Short Ram Air


163.3 WHP 4th gear @ 8550 RPM
115.7 WTQ

The graph goes straight up at 5700 rpm (VTEC) about 30 WHP

TQ is about 100 from 3000 (start of graph) to 5700 (up to 115) then falls to 100 @ 8300 rpm..

The best 1/4 mile i did XSI JDM Tranny NO LSD 16" Kuhmo's 712's

14.6 @ 96 mph

what do you guys think...

Going fully build LS VTEC over the winter (85mm bore)

 

your 1/4 seems weak imo for a crx..although it is an Si..
hrmm.
dyno numbers seem good though

 

how do you like the cams ? i have 402s but havent got to put em to work yet

 

very nice...

those along added 5 mph to my 1/4 mile

 

I had similar HP and lower TQ, ran 13.2 in a CX... so I concur with the above post about the 1320 being low.

 

Those HP numbers should warrant lower ET's.

Post the dyno graph

 

I am curious as to why they dynoed your car in 4th gear rather 3rd?

 

i did a pull in 3rd.. added 3 HP only

4th gear is closer to 1:1 gear ratio then 3rd..

4th gear are real numbers, 3rd are not as accurate...

Also don't have a scanner to post the graph

 

what whould i expect when i do a LS VTEC with this setup..

going with a 85mm Bore, full Port and Polish, Fully built..

Thanks

 

30whp jump on 5700 vtec vtec should be smooth..
