Fastest GTR and highest WHP GTR in Canada ?

[Skym]

There was a videoclip of a R32 GTS-4 running low 10.02sec in Japan (HKS drag meet and I think was car was built by Works Garage Redzone). I think was with a T04Z turbo. It's one of 2x R32 GTS-4's running similar 1/4mile in Japan, so no fluke.

Rough specs of the 9.883 R32 GTS-4 -

Extracted from Hyper Rev Club Skyline no. 9, 2002/2 edition:

HNR32 RB20DET 9.883s 1/4mile.

4WD, 2.4ltr, T88-34D 18cm2 (guessing A/R is roughly 1.23??), Tomei cams IN:272/EX:272, HKS FconV pro?, HKS EVC, 720cc injectors x 6, ETC+EDA, HKS 6 speed gearbox, OS clutch, and many other things in jap characters I couldn't figure out (things such as BCNR33 fuel pumps and RB26 plennum something??).

653ps at 2kg/cm boost.

I think it mentions 4wd controller ("ETC"). I noticed in Japan they show dynocharts of PS (same as US hp) at the engine, but EVO's that run similar 1/4 mile have that at the wheels.

This dude in Canada ran a 10.42 with a stock internal, stock cam RB20DET engine. It is close to a stroked, cammed RB20DET engine 1/4 mile -

It's actually very impressive for the minimal mods he has done. Just done them in the right places, like adjusting rear camber when squating (skylines are setup for grip / circuit, not dragracing), single piece prop shaft, etc.

I dont know guys. Lets plug the common sence back in for a moment please. RBs arnt made of concentrated unicorn blood. HP is HP mass is mass. It REQUIRES a given amount of HP to move a MASS a specified distance. No mater what the chassis it is in.
Now if we were talking about an RD with heavy mods the HP numbers could be down and still net rediculous numbers. the TQ would be aprox double the HP in that case.

Chassis setup and optimum gearing trumps all, I've personally witnessed cars running mid 11s at only 108mph, I'm guessing the cars were about 3000lbs or so (stripped out notchback mustangs). They virtually exploded off the line 60'ing in the 1.1sec range. I've also seen mid 11s at 135mph, it's all chassis, man. Look at my sig., my G-Tech was telling me that I only had 460ish HP on the 10.67 run, all it's doing is taking my known weight and calculating HP based on acceleration. Should I be going mid 10s with only 460HP on an unprepped surface? Most would think not.

All I'm saying is, chassis dynos are great and all but the real proof of how much power you have is the trap speed in the 1/4, even then it's an average and won't reflect peak. Trap speed is what you got, ET is how you are using it. If you are trapping above 135mph you have the power to hit 9's..........you just need to harness it to make it happen.

Dragon I dont know what to say, But comparing G-Tech vs track. Ya.

Ok this summer put your G-Tech in your car and use it at the track. just a couple times and you will NEVER compare the two numbers again. 127mph vs 134 mph is a monumentus jump in a 1/4. .2 bar does not equate to that much difference.
Your logic and talk of chassis HP blablabla. Proves enough for me. Your numbers dont jive.
You have 400+whp and that is good for a mid to low 11. Now look back at your sig thats what you got right.

O and BTW a stripped out knotch back is no where close to 3000lbs.

[Black BNR32]

man, a 1.1s 60ft would feel sick

that is all, ha

[hozer]

O and BTW a stripped out knotch back is no where close to 3000lbs.

not to take sides but my non-gutted R32 with extra goodies (Speakers, subs etc...) PLUS my own body weight, weighs 3,031 lbs.

[cobrAA]

If a 340whp stock turbos GTR tuned on a dynopack can make 12.01s.

and a 650whp did it at 9.7s both tuned by the same guy.

I can't see why some of you guys are saying we need 700whp+ to make it in the 9sec.

good traction and a tranny in excellent shape matters more than having high HP numbers.

[GTR-Dad]

Why doesn't an enterprising guy do the math on power to weight, accelleration, and friction coefficient.
Then we wouldn't have to actually race.

yeah, it's not rocket science :P

My car will be under 3000lbs with ME IN IT this year, with a 6 point cage and full interior. R32's just ain't as heavy as some think.

on the gtech issue: Back in the day, the 2nd gen gtech, I ran my rx7 and then went to the track. I went 11.8@123 in the gtech and 11.6@120 at the track. Perfect? No. But pretty damn close.

Here's the Works Garage Redzone R32 GTS-T (actually is a R32 GTS-4) at Sendai HKS drag meet (5:18+) running a 10:02 -

I hate to break it to ya, but my G-tech was within .1 of a sec of every run I made that day. And I made 13 of them, ranging from 12.6 to 11.25 as I was playing with boost level and weight distrabution. They are very accurate, you just need to set them up right. That 10.67 I have in my sig. was the average of 6 runs I made that nite (I actually made 10 runs but the first 4 were throw-aways for various reasons), the lowest was a 10.42 at 139mph. I reduced the mph in my sig. because the G-techs tend to be a little optimistic on the mph if you have a less than perfect launch.

A buddy of mine has a notchback that he just busted apart after building it up to a 700hp turbo 408ci monster that ran low 10s at 142mph and he was 3200 with him in it and a full tank of gas so I have no idea what YOU are talking about. He had alot of fiberglass and only a 6 point cage (and yes, he was asked to leave after he made that pass at 142 because they wanted him to get a competition licence and he said, "blow me, this is my street car and I'm racing in the Street Legal Class.").

I have been around the 1/4 mile game for 20+ years and have seen every possible combination and think that I may have a slight idea what works and what doesn't.

If you think that .2 of a bar with a T88 isn't going to add about 100hp then you are thinking what I was thinking, untill I felt it first hand. It makes a HUGE difference in power, no shi1t, it scared me a little the first time I felt it (and I liked that very much). You have to know too that I am running 32 deg of ign. timing on really good gas, not the pansy-ass tunes that most people have to run on 91 octane donkey-piss. The G-tech didn't assess the increase in power very well but when I saw the ET drop a full .5 of sec. that made me very happy (ET is very accurate with these things). MPH increased a full 10mph too. I know that the G-techs over calculate MPH by about 3 to 4 mph so I figure that 7mph is pretty safe, that works out to aprox. 100fwhp (remember I am at about 130mph, so HP increases are more per MPH than at 100mph because of drag, which Skylines have alot of).

Once you are over 110mph in the quarter with a cd of .35ish it takes much more HP to increase your trap speed. 10mph at 130 to 140 is a HUGE increase, that's why I know that if you are trapping at close to 140mph, you have the power to run 9s, you just need to use it.

Hey Jon, what are your 60-130mph times? just curious.

[Dragon Humper]

Hmmmm.......I can't remember, and my Gtech is about 10,000km away right now....LOL.

I do remember though that I was 0-60mph in the 3.9 to 3.3 range depending on how she hooked. At the track I was 60'ing in the 1.5 to 1.6 sec. range when everything worked right. When is didn't it was more like 2.2 to 2.4.....lol.

At 1.4 bar I know that 5000rpm to 8000rpm was over in less than 3 sec., pulled retardedly hard, much, much harder than 1.2 bar. With a T88-34D (22cm2) and the whole Trust kit that I have the turbo is just starting to work it's best at 1.4bar and starts to poop out at about 1.8 bar. The boost controller in the car had the overboost alarm set for 1.65 bar by the builder (Infini) so I don't think I will go much higher than 1.5bar without busting the motor apart to see what they have done inside.

With pistons and rods and some bigger cams at 1.8 bar I should be at around 850hp at the fly and 700hp at the wheel, good enough to run at least 145 to 150mph in the quarter.

But that is going to require a huge investment on my part, most likely in the $15,000 range for the engine and trans upgrades, not something I am going to be doing in the near future.

on the gtech issue: Back in the day, the 2nd gen gtech, I ran my rx7 and then went to the track. I went 11.8@123 in the gtech and 11.6@120 at the track. Perfect? No. But pretty damn close.

Actually that is perfect, if you ran the 11.8 on the street and then 11.6 at the track that is exactly what I found. At 1.2bar I ran 11.50ish on the street then ran 11.24 at the track. The traction made the difference. Usually your trap speed will drop a little too when you are hookin' and bookin' because less power applied in the first 330ft makes you ET a little better (once you get up there in power production) and drops your speed a touch.

With a standard tranny car, alot needs to come together just right to ET well. I've made about 100 passes in my car (now the clutch is going away.....LOL).
