with the two NA engines 3100v6 in the front and 90 toronado trofeo LN3 3800
both are rated at 160 Hp and all we did was port and polish the heads and up on em
we ran a best of 13.81 at 98.2mph with pretty consistent 1.90s 60' times at 4330lbs race weight
we are pretty sure we wouldve dropped a few more tenths if we had been launching with the rear engine at WOT and modulating the front throttle to the traction limits. As it was we had both throttles linked and were only launching with both at ~40% throttle
right now with the two stock L67'* we are looking for low 12'* and with a few mods 11'*

yup! aside from the 4t80e work we've been getting some stuff done (and yes there'* an ALDL under the hood as well as in the cabin....
this help the craving? lol
along the way i helped my buddy eric put a little whipple goodness on his 98 Riviera...waiting on the IS3 heads and cam...oh yeah he has a new 90mm FAST tb for it as well soon i should be done with the custom machined fuel rails
so far we have hit 200kpa at 10.5khz at just 4800rpm before we let off...
go figure...13+lbs of boost from a "stock" 3.8 pulley
just look at his **** eating grin....
and the 4t80e...the riv has it easy...the trans practically bolts right in with the aurora hardware...the 442 takes a bit more work lol sure looks like it'll hold up to abuse better than a 3500$ moderatly built 65ehd

with the 4t60e behind the front L67 still having the quad4 converter (higher stall for the 3100) when you get on it it stalls at nearly 4grand on a stock motor! (sure it'* got a 3.5...)
anyways our first joyride was with the rear at WOT and the front also, we launched hard and spun the fronts for a block THAT was Tq steer we left two nice stripes though lol
it launched much better with the rear at 100% and the front feathered in from ~40% up much less tq steer there! cant wait to get two 80e'* under it and see how equal length halfshafts help aleviate the Tq steer (not to mention a nice 3.71 gear in the rear and maybe a 3.48 or 3.11 for the front (leaning towards 3.4
i cant wait for the rear L67 to go in 'er

HAH. jees. you're planning on a SECOND L67? wow. So the LN3 just isn't movin it fast enough eh? Thats gonna be insane with two L67s... 480hp and 560 ft-lb trq stock.
on a 4300 lb car.
holy hell, that thing is going to MOVE.
then mod them to maybe 300 hp each...
600+ hp and probably 730+ trq total after that
wow. thats insanity.
