Power to the road

logikal · Post by **logikal** » Tue Mar 27, 2007 3:49 am

Im in a predicamint. I know for a fact that I 178 horses but thats on the dyno. when it comes to races though, I cant seem to plant the power on the pavement. From a roll, I can fly, but from a dead stop...well, lets just say a civic beat me me with a d16y8. now thats sad, and no it wasnt built, he had a blaster coil, some NGK plug wires, a AEM cold air and a n1 style exhaust from the cat. WHY?!? so basically all I wanna know is why the hell is my car not able to get off the line quick enough? Once Im out of first I can start gaining. So help me out.

what kind of tires and suspension do you have?

I'm not sure if you're spinning the tires or just have no power in low rpm.

If the tires are spinning, you'll probably be better off with smaller rims and bigger grippy tires. But to be honest, theres not too terribly much you can do without an LSD, as spinning in low gear is just the curse of FWD cars.

If the car just creates no power in low gear, which from your mod list I surmise it doesn't, then you could try to reorient some of your mods to create more low end power. Yes, you'd lose some power off the top end, but if you're racing Civics, you don't have too much to worry about. Small displacement cars need back pressure to create low end torque. If you orient all your mods towards freeing up the breathing of the engine, yes, you'll get 178 HP, but you'll have far less torque. That would be my guess.

I was thinking about doing that but Im producing 150 lb ft of torque which is the median tune I wanted on the car. that is why it is frustrating me so much. I was thinking of purchasing KW variant 3's and an LSD but I dont know much about drivetrains so I really dont even understand how an LSD works. Can someone explain?

Just gonna add my 2 cents here. I dont know what the standard output of the reno is, but I'm guessing you've added a fair bit of poke. If you are spinning the wheels through first, then LSD is the way to go, or suspension mods.

If you're not spinng through first i was thinking about suspension mods, I saw that you had Enkei Evo6 with Dunlop SP tires, that suck in the snow. I assume, these are the wheels off a mitsu evo VI with Dunlop SP's? If that's the case, has this wheel n tyre combo increased you rolling diameter at all, that would rob you of quite a bit of low down up n go. Then while i was thinking about the wheels i thought that if you have increased the specific output of the engine and the rolling diameter of you wheels then your poor old clutch is gonna hate you. Really need more info to help you with this..... could be one of a million things

As for info on LSD's go here: http://auto.howstuffworks.com/differential.htm

Are you making 178hp and 150lbtq at the wheels? I assume so since you said you dyno'd it. If so is your clutch slipping? I was having clutch problems with much less hp/tq and another member was having huge problems with about the same power your running (assuming its at the wheels).

I have the KW v-3, they're great... but pricy. I also have an lsd I dont know how much of a difference it made in a straight line as I'm into the corner rather than drag. But in the corners it's amazing, the car feels like it drive itself through the corners as if it were on rails!

hey Logikal sry to go off topic but can you post a pic of your costum strut bar?

Thanx

Yeah I could def. Ill take a pic at work tommorow since its currently raining. And yes Kinky the power is at the wheels. And my clutch is def slipping but not in first. I feel it slip through 3rd, 4th and fifth, and sometimes if my tires spin a lot, through second. the wheels were ordered at my shop and are 17" and the dunlops try there hardest to stick since they are great tyres. A friend of mine running a 300+ HP teg is running them with same size wheels and has no tyre spinnage. I think Im gonna order a set of the KW's through my work since we can get them for wholesale. thanks for the tips guys.

What is the full size for the tires? 215/40/17?

btw..I just order a buncha clutch kits for a group buy and got a couple extras that will be on ebay! So keep an eye out!

Whats the full mod list as far as things that would effect the whp? I have far more than you have listed, but am detuned a bit (long story) and am only making 122whp and 133lb tq at the wheels. Still my engine guy took a guess and said he could make 10whp more with a tune which is far less than you have. However I dont have headers but I will have headers, test pipe, and better cat-back within 5 weeks with a good tune just to see what she can do N/A before going turbo.

Full mod list:

MSD DIS-2 with 2 dual Gmblaster coils
AEM EMS
Dual flowmaster high flow cats
2.25" stainless exhaust with flowmaster thunderbolt muffler
11-1 compression wiseco pistons
Toga H-beam rods
wiseco rist pins and rings
Accel Super stock wires
spectre cold air
custom header
torque bar on motor(since I didnt wanna get stiffer mounts likke i could find them anyways)
P+p head
hp main bearings
hp valve seals
hp rod bearings
bored block to 86.5 mm
bored tb
DSM 440cc injectors
braided fule lines with Bg 200 LPH fuel pump and filter

thats all performance wise, and soon there will be a new motor with a nice fat TURBO on it.

Ahhhh, the wiseco pistons it is then! Very nice setup!

But hey, I have stronger motormounts, its just that they caused other parts to break so I'm contacting people trying to pick the right company to build the missing link.

I'm selling the listed for the forenza/renos D20. Ebay names kinkyllama!

Very good then Kinky, once you get those I will take a set off your hands for my turbo setup.

well in personal experience running a larger cat and then going down to a 3/4 of an inch smaller exhaust ( i had a 3 inch cat going into a 2.5 exhaust on my sr20de 240sx) and I noticed a big drop in torque and I swapped back to the smaller cat and the torque came back. but hey it could be numerous other things.

logikal · Post by **logikal** » Fri Mar 30, 2007 12:35 am

Its not the torque, its the wheel hop thats absolutely killing me. ALso the slipping clutch dont help.
