1/4 mile times?

TVT_DESIGN

Slow. Kevin posted a best of 12.3@117.5 with a 2.04 60' and spinning through 45mph.

With some better tires I would expect a mid 11.X at 120+.

RenntechE55

hey TVT_design check your PM's

Kevinw23michele

Yeah, I actually ran 4 times, and it was consistantly 12.3-12.4 with a 2.04-2.2 60ft. @ 117.5-118.2.

I am ordering tires tomorrow morning. Then I will go back and try again. Next step in my opinion might be a LSD.

Just to be clear, mekantor asked inpost #16 if it did anything for the restriction between the filters and the TB. The CORRECT answer is no, it does nothing to address that as it is all BEFORE the filters and the filter to TB connect. That doesn't mean it;s bad or good, just setting the record straight (unlike the filter to TB connect ). The solution is this AND the 80mm TB upgrade!

Kevin, my suggestion would be to optimize the power delivery. Right now if the results of your dyno graph suggest that the blower is running out of air, thus the large difference in HP and TQ numbers. My suggestion would be to open up the breathing as much as possible, this should help to shift the torque curve slightly upward and allow for some more usable power.

A restrictive system will result in more low end TQ as a trade off for top end HP. If we open up the system as much as possible then we will lose a little low end (with 600 TQ to the wheels you won't miss it) and gain a bit up top.

I'd also like to incorporate some hard lines into the intercooler to keep the pressure up and allow for max cooling.

Right now the best plan of action is to optimize what you have there. Even with a LSD it's still gonna be a PITA to control 600 TQ at 2500 RPM.

W/better launch/60FT he will indeed lower the ET, but the Trap speed will NOT go up, if anything it will decrease w/improved 60FT...

The current run is right on target for a BONE stocker, even the Trap speed (a few stock E55's have gone 12.flat-11.75 @ 118+mph

bassn_07

The trap speeds do look low and to be in the mid 11's I think you should be trapping 121+.

The first time I went to the track I trapped 122-123 consistently with my times ranging from 13.2 (very first run) - 11.7 with my 60' times at 1.99 - 2.5. I know these times suck but it was my very fist time dragging the E55. These times were done with Toyo T1R's.

TVT_DESIGN

Kind of sort of right. You need to look at it this way: you have a set distance to accelerate in, if part of that distance your acceleration is limited due to an outside factor then in part your distance is decreased. If a car is unable to grab traction till let's say 600' then you have lost that distance in a full on acceleration. If with good traction you were able to reach 80 at the same point you could only reach 60 with poor traction, then you will be on track to trap higher.

It would be a different case if say traction was only an issue in the initial 60' or so. There's not much to be gained in acceleration from that short of a distance.

There's a lot more to a good trap speed then just mashing the pedal and hoping for the best. Granted it isn't as dependant on skill as the ET, but it still has some factors that effect it.

Our datalogging on the larger pullies often show timing being pulled on cars not equipped with a heat exchanger. This is primarily a back-half of the track occurence, reflected in the traps.

chiromikey

this assessment is right on. any chance we can get timeslips posted to see split times and help figure out why this car isn't running as strong as it should be???

prodigymb

yeah. i'd want to see the 1/8 mile trap speed too.

getting better tires will drop the et but trap will not really go up. in my drag strip experience - most of the time trap speeds go down with faster 60' times.

Kevinw23michele

Hey guys,

I will scan the time slips and post them up, but probably not until tomorrow. I am in the office now, and left them at home.

prodigymb

you'll get there kevin. it takes practice too. took me 10+ passes on this car to get my 60' to be consistant 1.8x on 19" wheels and street tires. 1.8x is nothing to brag about but i am just not seeing anything better from a 19" rim/tire setup i have . . . i havent really seen anyone here go faster on 19s.

chiromikey

sure you have...how about 1.71's.

prodigymb

that is quick !!

you?
what tires?

chiromikey

yep...i have many 1.71-1.74 passes on toyo t1r's but only when the track is properly prepped.

RenntechE55

They are crap they are not long enough and the driver side does not fit I will be sending them back. i guess you get what you pay for.........

Bisco

Are you serious?

Let's here TVT's take on this...

I would like to hear TVT's take on this to maybe they messed up my order and sent the wrong tubes. I would like to see better pics of the ones they have put on a E55's. I will take and post pics of them on and off the car. I managed to get the driver side to cram in there and went for a short ride maybe 1 or 2 miles when i got back the driver side had come loose and the tubes were pretty hot probably meaning there wasnt enough cold air flowing through them? not trying to bash the product just stating facts because you asked how they are.

pics please

RenntechE55

i guess i got nothing to do right now so ill go take some if i can find a camera.

TVT_DESIGN

Wow, I get a PM asking for a refund and a few minutes later a bash on the thread. Be a man and at least let me respond privately first.

I'm sorry that they didn't work out. We haven't had any other fitment issues from the others we have sent out. Unfortunately not every piece is going to be a perfect fit, as is the nature of production.

I'd be more then happy to issue a refund though. Pack them up and ship them back.

RenntechE55

not trying to bash i specifically said " Im not trying to bash just stating facts because you (Bisco) ask how they are ". Can you post you post some pics of the other cars they have been fitted on? Maybe I'm installing them wrong but i dont see any other way to make them fit. They just seem like they were not built for a E55.
