A 2.1 or 2.2 60' is good but a 2.650 with 6.55 330' and 9.5 1/8 @ 83mph is just sad.

 

Lol wow yeah that's pretty bad. Forget street tires heh they are retarded with a turbo max.

 

Makes my 2.49 60' on street tires look pretty good.

 

Congrats Mattsy! Finally making the dream a reality!

this is matt racing the civic corey is talking about. They obviously are there to film for the civic so matts ET and mph are not on the screen in the end.

Thanks gtr_rider...that worked for me.

Mardi

 

nice vid, you probably have the civic in power but not in weight.

 

Pretty nice vid...way to keep up with him

 

with A 1.6 60', 10's are possible, with speed of close to 120mph.

 

Mmmm...10's

 

he is almost trapping at 120mph w/ a 12 flat.

 

wow what was that Civic's 60'? 11.0 at only 105 mph

 

11.0 @ 105 is imposible the civic must of let off early probobly around the 1000ft mark

and the civic probobly has about a 1000lb weight advantage so its really not a "even" race

 

A race is a race...the civic may weigh 1800lbs but Mardi has two more cylinders, you could go on all day going back and forth like that. It really doesn't matter, he has what he has and you have what you have.

 

No doubt he let off, thats a 9sec car in NHRA trim, I talked with the driver for a few minutes in the staging lanes. I have the slip at home from that race and will get you the details. He put down deep 10's in qualifing, he was the #1 qualifier.

Soooooo Clutchnet cant help me. The only thing that looks like it might work is the ACT Extreame PP and six puck solid hub. I might get that ACT PP and Clutchnet sprung hub disk. I had a long talk with ACT and they insist that the sprung hub is only to dampen vibration. He said at idle it will make a whiring noise like a twin disk. Other than that it is no harder on the drive train than the sprung hub and the springs in the sprung hub are just another thing that can fail. This set up is rated to hold up to 572ft-lb, I think that should do me for a while. They have an even heavier PP that will hold 667ft-lbs, but is race only. I want the car to still be streetable, even bairly so, but streetable. Corey has talked to Clutchmasters and we are waiting to hear back from them.

I guess the question is how much TQ am I putting down. Perhaps 450 with the 35shot and 525 with the 75 shot on top of the boost. Maybe I can set the nitrous window switch to only engage after 5500 rpm to the torque is less but power is still their up top. This shold still help on the big end of the track. I would think the ACT 576ft-lb set up would hold, but I guess you never know till you try, what other coice do I have? Or it might be time for a dyno.

 

I would say dyno it then do the clutch so you at least know your numbers,.

 

dyno is cheaper than $500+ clutch

 

if you think the clutch will hold on the dyno do it

 

usually their torque numbers are a little conservative so you should be good...but i want to give you an excuse for the dyno too so better check the tq. #'s first.

 

dyno,dyno... Why not just dyno her,instead of guessing.

 

I'm curious as to why you believe you'll only be putting down 450ish wtq on the spray? My car (when it was hal's) put down 505ft lb on a t3/t4 at 10psi with 65 shot and 603ft-lb with an SP66 at 14.5psi and a 65 shot. You didn't specify a boost level but given what I've read in this thread you are thinking of as much as 17psi + 100 shot? That should be worlds more than 450ft-lb unless something is majorly wrong...

 

i think something is wrong with his car.

 

SP66 is a ~600"W"hp turbo, Turbonetics 60-1 is a ~500"B"hp turbo. Im way outa turbo. 9.4CR hurts a bit, but the extra displacement should off set this, No control over ignition timing is a big issue. We all know the JWT ECU is soft, I need it for the 740's. Once I get the clutch straight thats my next thing. If the EU works to increase the revlimit thats an option or JWT/LightningMAF/100oct tune. It maybe 500 as it sits with the 75shot, but it couldnt be much more , it should be dynoed late next week sometime.

 

Why did you build your engine with such compression?

 

You're kidding right?

 

Im not kidding, he should have done 8.5-9:1 comp.

 

Per his webpage, he wanted to keep the off throttle response.

If he was having detonation issues or if he had already broke the motor then you might be right. Why do you think he should have gone lower?

 

This way, he wouldn't need the 100 oct program, and the his engine would be that much more heat/detonation resistant.

 

He is getting the 100 oct program for more aggressive timing, it has nothing to do with his compression ratio.

 

Ignition timing with the JWT ecu is pretty conservative and takes care of detonation issues. Not only that, but Mardi is using J&S Safeguard to further retard timing if detonation is detected. Lowering compression down to 9 or below is unneeded for the amount of boost Mardi is running, and like Mike said, hurts engine response.

I reach 14.5 psi non-intercooled (supercharged) with stock 10:1 compression (about 13.2 psi with the FMIC), and I have never detected any detonation at WOT with the JWT ecu. Would I make more power at that boost level with more aggressive timing and lower CR? Maybe, I don't know, but I really like retaining the crisp response of the VQ when I'm not boosting.

 

i was thinking the same thing stephen. with my other motors i was spending too much time and money lowering the compression so after blowing another one, i decided just to rebuild a stock 130 motor with new internals thats it and the car is running really nice. i dont plan on going over 11lbs with s/c so the lower compression means nothing to me right now. but for once and all im going with the j&s safegaurd immediately to avoid blowing my motors again. mardi can you please pm me on who to talk to and which unit to get for my 97 im ready to order today thanks. p.s and why the i30 motor is because i had a low mielage one hanging around so put it to use.

 

Just call J&S for the information.

 

oh i forgot he is running a teenie weenie turbo.

 

what size turbo are you running?

 

How about people try reading the thread before asking questions

 

It seams that Clutchnet can do a double diaphram pressure plate that will have 2900lbs of pressure. If I send them my current PP that is already seated from my current disk they will do the modifications to that so I dont have to get a new clutch etc. For reference the ACT HD is 2260lbs and the ACT XT is 2700lbs. The ACT XT will hold 576fltbs so I'd bet the Clutchnet double will hold ~600ftlbs. But boy-o-boy will it be heavy
