If my calculations are correct and yes i can use a calculator :

85 FB 2500est Lbs./350 HP = 7.14 lbs. to HP

86 FC Sport 2650Lbs./350HP = 7.57 lbs. To HP

93 FD Base 2789Lbs./350 HP = 7.96 lbs. to HP

2008 Nissan GTR 3858lbs./473HP = 8.15 lbs. to HP

2008 Evo 3594lbs./291 HP = 12.35 lbs. to HP



What im trying to say is if 350 hp in an FB/FC/FD can take out a 2008 GTR must be great to blow the doors off one in a car that is at least 16 years old and give a run for there money on cars like the 2008 Shellb GT 500 and The Corvette Z06 which has a little better hp to weight ratio. hell even a Lambo Murcielago is a 6.12:1lb hp to weight ratio

Forgot to add this is based solely on HP figures TQ is another thing all together LOL https://www.nopistons.com/forums/pub...#>/biggrin.gif

My Legacy with me in it is about 8.7 lb/hp and it's pretty fun.

ColinRX7 01-08-2008 10:36 AM


350 hp in an FB/FC/FD is fast!




... And you're just figuring this out now?

phinsup 01-08-2008 10:38 AM

I'm going to do a diesel swap to get some torque https://www.nopistons.com/forums/pub...#>/biggrin.gif

ColinRX7 01-08-2008 10:46 AM

You ever seen that race truck dakota with a diesel in it?

Rob x-7 01-08-2008 11:04 AM

Banks had a turbo truck he would drive to bonneville with a trailer behind it, make some crazy high speed run, then hook the trailer back up and drive it home.



was far too, a few thousand miles.

phinsup 01-08-2008 02:56 PM

There was an article around not too long ago about a twin turbo diesel corvette, thing had like 650 ft lbs of torque or something obscene like that

RX7 13B 4 UR AZZ 01-08-2008 09:17 PM

just never realized how low a hp figure a rotary needs to whip ass

vosko 01-08-2008 09:29 PM

mazdaspeed7 01-08-2008 10:06 PM

Thats the one I was thinking of. Was it a dakota? Or a 1500 ram?

vosko 01-09-2008 11:08 AM

my drift car is 2501lbs and 414hp(flywheel) so that is 6.04lbs per hp.... https://www.nopistons.com/forums/pub...IR#>/smile.gif

RX7 13B 4 UR AZZ 01-09-2008 11:25 AM

that is sick vosko that is even better lb:hp than the lambo LMFAO ! ! !



And you guys are right but I bet you you will have alot more fun whipping ass in an RX-7 than in a GTR I am going to love the day i roll up to a GTR and hand it its ass in my 86 im just going to laugh and laugh.



Quick question the GTR is supposed to have a top speed of 193 what besides gearing, drag, hp will limit a cars top speed? like vosko's car has a better hp:lb what would keep it from going up to lambo speed?

vosko 01-09-2008 11:49 AM

exactly what you said. gearing and aerodynamics and raw hp



anything above 175mph gets iffy on a street car

RX7 13B 4 UR AZZ 01-09-2008 12:00 PM

i would not even dare i got up to 150 in a fd and its scary it would take some big cojones to go 175 even 193 GTR top speed

vosko 01-09-2008 01:52 PM

i did 175 once...

dakota, I think they called it sidewinder or some ****



acceleration is nice and a quick blast to speed, but to drive 175mph on a road is ******* retarded and irresponsible

RX7 13B 4 UR AZZ 01-09-2008 04:33 PM

no one is saying to go out and do it but if you are crusing along at 3 am on an interstate and a gtr(highly impossible) rolls up to you and you get into the heat of the race its hard to resist even me that i dont run it unless it is a worth while race i could not resist.

75 Repu 01-09-2008 08:14 PM

there was a little dispute recently about banks speed records.. he holds em.. but Spal had a ford ranger that set a record supposedly.. but not with the FIA.. and they were tooting their horns about it last year.. yet banks' truck still holds the record and is like 5 mph faster.. i read it in a truckin mag recently..



did i make any sense?





banks set record in 2002.. for like 216mph.. recognized by the FIA.



Spal made a pass for 211mph in 2007 and that was apparently a record according to what ever company recognized their run.. but it was not the FIA.(which is a internationally recognized organization) hope i got the acronyms right.

it can leave twice as many strips on the ground when you launch it too

I'd try to stay out of "the heat of the race" on a public road.

ColinRX7 01-11-2008 10:33 AM

I've done stupid **** too when I first got my FC 5 years ago.



Just becareful out there. The insurance premium you'll pay is not worth it.

teknics 01-12-2008 03:56 PM

yea when i first got an rx7 I would do stupid ****, but stupid **** gets boring and dangerous pretty quick. now all my friends whoa re just getting into cars think I'm a *****, I just shut my mouth and wait for them to come home with an 8 point speeding ticket.



kevin.

RX7 13B 4 UR AZZ 01-15-2008 09:19 PM

i cant say i did not do some stupid **** 2 but getting off ramps sideways is fun
