The only way your going to beat an Si is if he launches below the Vtec crossover. You should be able to out launch him anyway, but the Si will catch you around the end of 2nd or 3rd gear.

the si runs high 15's, the spec runs between mid 15 and 15 flat. If you run properly you should beat one no problem.

Then why hasn't he?

that question has got me stumped too
I've never raced an si so I have no personal experience with it
car-stats.com has them rated at a 15.7, now I know they can be off, but normally not by over a half a second.

To beat an Si, the Spec V MUST be launched damn near perfect. These cars seem to be the best rivals going on lately. I have personally raced Si's with my B12 and 1st den DSM (NA). My B12 easly outlaunched the Si, As I can launch very good and my car wighed 2100lbs. My DSM took an Si off the launch too, thank god for a 4000rpm stall

I went to the track again today and did 2 runs both were 15.4. a little better now , not that bad, im all stock. There was a yellow SPEC there. IT was a woman driving it. she did a 17.2 (MISSED 3rd gear. my god thats bad. Her husband did a 15.7. I launched at 2000 and dumped the clutch. my 60'' was 2.373 and second run was 2.349.

the spec-v and the rsx-s are the bitter rivals right now, an SI shouldn't even be a challenge if the spec owner can drive. This is the first time I have ever heard of an SI beating a spec, maybe I should go out and find one so I can see for myself.

Nsane18 · #23 03-08-2003, 03:09 PM

The reason for the Si being the Spec V's main rival is becuase the Spec V is so hard to launch, and the cars run almost the same time on the 1320. Top end, i do believe the Spec V takes the Si. As for the RSX type-S, If the driver can drive goos, they can walk the Spec V.

I've been racin for 17 years now and i never thought i'd like this rice so much.. the torque on the Spec is the key a good launch about 2200 and good modulation with quick 6500 second gear shift and i'v walked rsx-s wit inake and exhaust .. now i have a Cia and an aftermarket exhaustas well as no cat timing advanced about 1-2 degrees and runn sythetics blended in this fashion 3.5 quart of 5w30 and .7 qarts of 15w-50 mobil one.. that takes care of the high taching that you all will freak out about.. the spec v is designe in my opinion for much higher rpms..and i wouldn't be surprised if Nismo comes out with a a controller in a year or two to set upthe engine for a 7500 redline i mean its dual overhead cam multivale variable valve timing.. hell my pushrod LS1 redlines at 6250 and it kicks midish 11's consistant

Shit even with just the Cai and the sythetic.. i wasted my nephews 2002 IS300 5 speed I6..

Author the car can do it.. you have to practice and relearn everything.. or unlearn everythng you know.. you should nal a15 flat with no probs ad Si, rsx's Vr6's and the like you should own .. hell man i beat a 4.6 98 mustang Gt and he wasn't stock.. boy you wanna talk about being pissed.. that why i don't like fords.. even their cobra and Mach 1 is a joke to my vette or Ws6.. they are always playing catch up.. go out their and kick ass

The Spec V doesn't handle high rpm because of it's valvetrain. It's valvetrain will easily handle 7500rpm. The reason it won't do high rpm because or the motor's rod/stroke ratio. The long stroke(hence a lot of torque) and short rod cause the motor to have high stress at high rpm. This also causes port velocity to be brought up quicker, but gets unstabe at high rpm. If you want the Spec V to rev to 7500rpm, you'll need to de-stroke it and use a longer rod. Rod/stroke ratio is the reason you V8's won't rev worth shit, and you have tons of torque.

Spyk · #26 03-09-2003, 06:03 PM

Well i wouldn't say that.. my ls1 has a rev kit and i can go to 6500 without vavletrain damage.. but i set the rev limiter to 6250 the LT% redlines at 6500 as well..and the Lt1/lt4 Roadmaster conversion i built redlines at 6400..

Now when i run the Spec v i shift at 6500 it doesn't cut out.. you sure that nismo doesn't have somthing on the horizon that will increase it to 7000.. i mean hell if my V-8 are nailing 6500 i can't see why the spec shouldn't have a little more go uptop with ou destroking.. i mean this motor is bulitproof according to the japanese.

but understood what you said..
it just amazes methat it can't hit 7500 the way it is with out damaging or losing power.. cause it sure still feels strong at 6500 it hsn't flatened out yet

thanks for the reply

Actually the tq curve does drop off fairly rapidly once it gets up around 6k. Once the engine hits about 6800 you start to get valve floating and then its just downhill from there. In order to rev even to 7k you would have to have atleast new rods and springs, then destroking would also help to prevent damage. The qr25 is by no means bulletproof man. The open deck design is pretty weak, and earlier tests by JWT and others showed the engine self-destructs around 275whp. If 275 is considered bulletproof by the Japanese then that is pretty sad, especially condidering the sr20 can handle up to 400whp on stock internals.

Spyk · #28 03-10-2003, 05:58 AM

Thanks .. i can handle new rods and springs myself.. wel i should have an import guy there looking over my shoulder.... Mna i was sure i read in a 2000 issue of scc mag that the Jap spec v version was capable of far more hp than 275 though it was in its early pre production stage..
if i find the article i will quote to you from it.. not that i believe "anything ' in an Import mag... J/K

So my V-8 don't seem to shabby after all and they are produceing gobs of torque& HP well over 6k

their is still life in the old pushrod.. don't count them out quite yet.. i have a couple of friend withtthe appropriate cams and other vavletrain mods pushing 7k in a ls1 and pulling all the way up their.. not bad for ohv technology

later and thnks for the info

sr20de4evr · #29 03-10-2003, 08:49 AM

Yeah, I have a lot of respect for the american muscle, just not the cocky rednecks you seem to see everywhere that think their v8 is the best thing since sliced bread

. I'm sure with the right internal mods you could push 7k in the spec, but you wouldn't be making any power up there unless you got i/h/e/cams, after those I think a while new world would open up. It's really interesting you saw an article about a jap spec-v, because I was under the impression that the spec-v was not, and will not be produced in Japan. Maybe they imported one from the US and started working on it...

Spyk · #30 03-10-2003, 09:00 AM

WLL the mag is a 200 SCC and i remberthem talking about it.. heres h catch it was the 2.0 making 175hp
the article as i remeber went on about the rocker and the lightweight material and thelook of non durability but upon closer inspection the said the design was from their racing vavletrain

If you have a Fax number i'm sure i can find t and maybe you could lookit over.. it got me interested in imports again.. i dropped out for awhile.. with all the America bashing.. i mean take my ette itsa 93.. but the same engine was built in 89 a four cam 4vavle 405 hp marvle 350.. thatthe same hp rating the zo6 has tody 12 years later same displacement.. but in pushrod 2v cam in block so its cnsidered the techincal marvel.. America can do it.. it just a matter of why when we can use pushrod v-8 and still get the job done.. you know thold saying ..if it isn't broke why fix it..

get back to me wth a fax and i'll see if i can get it over to you today
