Well I know of a few 10 sec 1/4 mile WS6's that will pass a smog & be reliable on an daily use. I don't see you taking the NA to those times without affecting the reliability & matching comfort that the WS6 will provide. In an auto x type situation NA FC for the win. If you want to compare stock for stock & not have either side have mods still a win for the WS6 in the 1/4.

FC3Sboy you said your car weighs 2144 lbs, we will say that is with the weight of the driver okay. 2144 lbs @ 205 rwhp would put you in the mid 12's at around 107 mph. Now this car I would say to get to this weight would involve some cutting, lexan & loss of some items needed to be a functional daily driver. A stock WS6 can pull a 13.2 @ 108 mph on a standard tire, I have seen them run in the 11's on a BFG & a 150 shot. Throw in a cam, header, exhaust & some suspension & you are on your way. Trust me I hate these asshats with their nitrous & semi slicked V8's talking ****, but when comparing the cars you have to factor in the level of modification involved to get each to a predetermined time & mph. At the end look at what you have, which one could you take on a trip, to the store or just chill out in.

i have seen first hand what ws6's can do if it is an LS1 with spray an na rx7 will have to be a P-Port Nitrous breather to run with a ls1 ws6 and even then. I do installs in cars nitrous, ecu's, ect... i installed a direct port nitrous kit on a 2001 camaro LS1 and it was set up for a 200 shot car had computer work CAI, msd ignition, Full length headers and straight through exhaust, and was geared and running slicks and ran an 10.9 in the 1/4



Just math/paper racing

ls1 camaro 320 bhp(conservative Stock HP) + 200 Shot + Bolt On's = estimated 580hp/3300 curb weight 5.7lb per hp

S5 rx7 160 bhp + 150 shot + bolt on's estimated 330hp/2200 lb 6.7 lb per hp



you would need a 385 HP na rx7 to at least match on paper and a 385 hp N/A 13b is a little unrealistic IMO

RotorDad

Like said above P-port definitely would be needed & to get the car down to 2144 lbs is a stretch for a daily car. I agree with 13b 4 UR AZZ in saying it would be unrealistic. You would need a highly modified NA FC to compete with a lightly modded WS6 in a straight. So beg to differ all you want FC3Sboy, but take a moment to really think about the situation before opposing.

Im not at all saying it cant be done I saw a suzuki side kick that was peripheral ported and a direct shot of an un known amount run 10's at the track a few years back but the guy blew the motor mid track on the third run of the day. the whole front end of the motor blew off like if it ripped the threads out of the front iron. they where revving the **** out of it to get to launch right if not it would bog out. no way that car could be driven on the street so all im saying that it is unrealistic to make any kind of power on an n/a and have it street drivable or even reliable drag racing.

RotorDad

Yeah I never said it couldn't be done either, just I don't agree with his statement of it being easy to accomplish. I definitely think sacrifices would have to made & in the long run money could be spent more wisely in a different route to the goal with less of an issue as a street car. To look at the fact that there will be some sort of budget involved & given that the WS6 would take less to achieve 10's & still could be used in an everyday situation just seems more practical. BTW 10's are just a time for comparison. A well built & tuned turbo car would be a better choice IMO, but if someone is set on maxing out the NA then that's their decision. Also remember nitrous is a power adder thus changing the dynamic of the NA, but I guess that doesn't matter since we are talking what it would take to get the NA FC to beat the WS6.

RX7 13B 4 UR AZZ

true adding nitrous defeats the n/a dynamic LOL so to put it easier the only way to beat a WS6 with an n/a rx7 would be if the engine is on a go cart then i see you going after Ferrari's lol

RotorDad

Hmmm sounds like a great idea, Go-cart + BP 13b!

RotorDad

Thank god you got rid of that overweight & under powered car. VR4's can be nice, but SL should be followed by OW. Not to mention the FWD set up in the SL was a terrible idea.

I had a automatic 1994 SLow with a few mods (Spray, Headers, Intake, Cam, Cam Gears, Underdrive Pullies, Full Exhaust, Trans shift points raised) and let me tell you it was anything but SLow it was a monster on the highway id hang with a few cars i never thought possible
