Had a little action this weekend http://home.koping.net/u3243a/tillfalliga/B1.wmv
have Qa1 in front (315lb springs) no front swaybar, adjustable KYG shocks and lowering springs back, spohn torquearm, SFC, Relocation Brackets, boxed controll arms. 26x11,5-15 ET street, Also had full tank and a 6gallon watertank in the trunk.
I need more weight transfer so stock rear springs are on the way and 2 other ideas came up.
What do you think of moving the rear axel forward a little bit?
Is it any noticeable diffrence on the 315? frontsprings and a pair of 275lb ?
any other good ideas?
thanks

You aren't gonna hook unless you guys spray VHT down. Or unless you start controlling the throttle better. Looks like you're just stabbing it right away. My car spins the E/T streets on asphalt and I'm making no where near the power you are.

 

Nice sounding car for sure. Some 28X12.5X15 ET Streets will work better, or just a 28X10" ET Drag.

You definately got worked by a big tire car. hehe

 

controll the trottle? yea but i still need more traction, against the cevelle (572cc n2o 2810LB racecar) it wasent really much more to try when he jumped ahead
at the first try on the clip i only gave around 50% trottle the first 100-130 ft (you hear the revlimiter when i go wot)
VHT isnt really an option, nobody use it here when we go streetracing.
28" tires, yepp just gonna finish these first. are there room for a set of 28X12.5X15 ?
anyone more that have any ideas?

 

for the 28" tires you have to cut the rear bumper a bit right behind the tire, or if you have adjustable rear LCA's you could move the axle forward a bit to clear the rear bumper. As far as traction issues, try to stiffen up the rear suspension a little more and even going with a bigger anti-roll bar in back. For the QA1 question, i just switched last weekend from the 315 lb springs on the original QA1's to a set of the newer QA1 R series to keep my k-member from hitting the ground. these came with the 275 lb springs and i like them a lot. i have a cam only LT1 on stock unported heads with a 150 shot. A th400 with a brake and a ford 9" and i street race quite often around here and have never had traction problems. my car cuts a 1.4 60 ft on the juice and hooks every time. also do you have any weight reduction or your battery relocated to the hatch?

 

i just watched your video and also do not roll out of your burnout that far. it picks up alot of crap from the road. only roll out a couple feet. what do you do your burnout in?

 

burnout is in water, good point about the rollout havent tought about the crap thats on the road. (did you hear the rock that i shot backwords in the first burnout? glad that it didnt hurt someone)
weight reduction, front and rear bumpersupport, use to have a 15lb battery in front but it has given up so untill i get a new one i use a stocktype, no front swaybar, no AC, frontrunners on the strip magnesiumwheels on the streets, lightweight driverseat (rest inside is stock) on the + side i have, supercharger, FMIC, 5point rollbar so i guess the weight is almost as stock or more.
did cut 1,54 last year widh stock torquearm and front suspension (lowering springs) so i guess 1,4x is possible eaven on oure tracks (not so good prepped as youres)

hmmm maybe a good idea to get adjustabel LCA to get the axle little forward to the next tire change then

how does the 275lb springs work in ordinary street driving? (without swaybar) and was it a bigg difference in weight transfer?
thanks

the 275 springs in the front feel more street friendly than the 315's i had before only because i have the new r series shocks with the set compression so the car doesnt bounce all over the place like it did before. also i usually just stiffen up the front qa1's for normal street driving to make it a little easier to turn corners. i have no power steering and i have a spool in the back so turning corners isnt much fun anyway. also is your pinion angle set correctly. i'm assuming you can adjust pinion angle with the torque arm you have now. the biggest difference in weight transfer i noticed was when i moved my battery to the hatch. also this may sound funny but it has worked for me when in a pinch during the late night steert racing, try some mountain dew or something similar to do your burnout in. it gets very sticky when hot.

 

Try going to the track.

 

pinion angel set to 2-3 degrees, mountain dew OK yea it sounds a little odd.
going to the track, yes as soon as they open, have at least 3-4weeks beafore the first preped track opens, a teporary tracks (old military airport) has a race next weekend but im afreid of getting the same problem there....

 

You guys need to invest in VHT. You should be able to do much better on a 28" tire.

shady93z- Never though of using Mt. Dew. That's different.

 

How many pounds in the back tires?
I don't think you can quantify traction problems until you have a controlled environment to test on and compare.

 

i have tested 16-24psi.
as topic says "need more" dont think i will have any problems to cut low 1.5 or high 1.4 on a prepped track but i planing to run a street race cup ( "RUN WHAT YOU BRUNG AND HOPE YOU BROUGHT ENOUGH" ) this year so there for the questions. Also planning to take it to the track a couple of times to see what the winters upgrade have done so any traction improvment for the street will properbly be usefull on the track as well.

anyone having any ideas about gains if i move the rear axel 3/4" forward?

 

I don't know about relocating the axle.

I do know I have cut low 1.5's on 26" x 11.5" x 15" Et Streets on 15" x 10" rims with my car. I run 14 pounds of air in the ET Streets and 45 pounds in the front skinnies. I have Eibach drag springs on all four corners, a 6 point welded bar, no front sway bart, no subframes, stock shocks in back and 90-10's in front, no front sway bar, battery is in the trunk, and the drivers side tire comes off on a decent launch. I launch off idle and have a 3600 stall converter. There is one air bag on the right rear side with 20 pounds in it.

I have virtually no traction issues whatsoever. A good clean burnout and roll out as close to the line line as possible to minimize the risk of picking up debris. Even on a questionable surface I can usually hook up.

 

hmm maybe im overreact, its only 35-40 degrees nighttemp an around 50 daytemp here now so the asfalt are very cold, will wait widh the rearaxel relocation, have just modified the rear swaybars mounting bolts/tubes so i get little preload to hold up against bodyroll and should buy a new lighweight battery first. havent succeed to lift the front tires at the track yet but it is close (pics from last year widh stock TQarm, loweringsprings and decarbon schocks in front)
