cp-e N54 Port Injection Straight e85 Review

[trebila]

I already disabled the cold start function in Marty's 100% E85 bin.

Let me know if you still get hard cold start.

[martymil]

Yeah still has a hard time sometimes

11.9 @ 117.6 mph tonight so far 1.8 sixty on absolutely crap tyres.

The track is absolute crap tonight spinning 1, 2 & 3rd

[Forced_downunder]

I'm off work next Wednesday. May head down to see what I can do with my car. Marty if you're around would be good to catch up and better if you have the new tyres by then too

[martymil]

Hopefully I'll have them and definitely should be there next week.

Best tonight was 11.8mph with a 1.8 sixty foot with wheelspin

logs looked good, i'm cranking some good top end boost.

At least I had three runs in a row running 11.9, 11.8, 11.9 nice and consistent now, before the times where very erratic.

Very happy with the result.

It will be interesting to see what you can do when you get the traction issues sorted, maybe you could chop 0.5 second off your time, a mid 11 would be quick!

What were your traps?

[martymil]

119mph was my best

[DR-JEKL]

Whats the issue with the slicks?? were they fouling the guards?

[martymil]

They where sticking out of the guards by about 1.5 inches

I think the offset was for a 335

lol, and i ask again what was the problem with the slicks

What rims did you mount them on and what size slicks were you intending to run?

[martymil]

I borrowed them from a mate, nothing wrong with the slicks accept it would have damaged by guards

He already had them on rims so at last minute I tried them on and they didn't fit.

Time to hack your guards up with an airsaw and bolt on some SLR5000 style bolt on flares

Ended up getting some Nitto NT01 semi slicks yesterday,

They seem to be holding the power very well.

Have to see how well at the track.

The great thing about these tyres is the more they wear the more grip
you get. You can actually shave the rubber and turn it into a two groove slick.

they wont be ideal for drag racing Marty, as the sidewalls are extremely stiff as the NT01 is a circuit tyre...

What diameter rim did you get them mounted on?

Ideally the NT05R's would have been a better choice, but the NT01's will most likely be a lot better than the 20" nankangs

[Forced_downunder]

I'm looking for a drag type tyre. NT05R's are not available in 256/35 18". Any suggestions for a DOT approved tyre. The R888 sounds like a natural option but it's not a specialist drag tyre. Looking for something that doesn't need a burn out to warm up for my next 2 x 1000m events. Anyone know of a Mickey Thompson tyre that will work or a suitable alternative?

hoosier do a drag radial in a 245/40 18, whilst this isnt as wide in section as a 265 these would be a lot stickier than a typical street tyre..

https://www.hoosiertire.com/specdrag.htm#DOT Drag Radial

All drag radials will require a burnout for them to work effectively though to prep them for a launch... If you were serious you may wish to get a line locker kit also

If you were going to get serious enough to get some slicks get some dedicated drag rims also, hooseir do a 275/40 17". These would most likely require some guard mods or you could go down to a 16" rim, hoosier also do a 255/50 which would be a nice meaty sidewall with some flex in it

Like all comp tyres you should pay to have them heat cycled before use

[martymil]

I got the nt01 only because that's the only ones that where available on short notice, I know it's a track tyre but it's going to be and is a lot better than my spare set of r888's I have two sets of them sitting on the shelf from my Evo x

We will see the next time I go to the track don't know if I'll make it this week, booked out solid with work

The problem with Mickey Thompsons is you need medium to large burnouts.
I use to run them on my supercharged vk Calais back in the day on 15 inch rims.

NT05R's and NT555R's (none in the country)

For street use and occasional drag NT01 should be sufficient, let you know how they hold up.

[Nugget]

R888s are a decent option for 1000m events.
They don't need a lot of warm up and they are fairly stiff so will be stable at the high speeds you reach over the 1000m

[martymil]

The power Greg is making I highly doubt the r888 will hold

Are mickey thompsons rated to go at the speeds you are going to be reaching over 1000m ?

Greg I have 4 sitting in my shed your welcome to take them 245 40 18's

[Forced_downunder]

Thanks Marty. I may take you up on that. Very generous. Will see about a second set or rear rims.

[martymil]

Hi guys, so having this kit for a couple of weeks now things have been fun, got the tuning sorted no final power figures yet.

I was always boosting to 23 psi tapering to 13 by redline now i'm boosting to 19 and tapering to 15.9psi at the the track and making more power on the dyno.

All things considered best bang for buck compared to other kits, with a return line and regulator this kit is suitable for a 1000hp I've been told. I'll never see that I guess.

I need a bigger intercooler now as with making more power the inlet temps started to creep up even with one of the best on the market that I have

Meth is the way to go and the easiest to bring down the temps but is also very corrosive to aluminium and that's why its not recommended with the PI kit.

I'm extremely happy with the outcome still need a little fine tuning here and there in the back end flash but overall I'm happy.

[Forced_downunder]

I've been envying those darn good looking Plazmaman inter coolers too. Bigger FMIC will allow better performance especially on those hotter days.
