Hey I have searched and read a lot, just wanted to clarity to my specific setup.

I'll be making about 480 whp on 93 with my full interior ITR, running competition stage 5 clutch with upgraded PP, and 15x7 TE37 Volks +35 offset, with 225/50/15 BFG drag radials on STOCK axles

As this is my first high horse power car and first turbo build...what kind of times can I expect at the track? I was hoping to be in mid 11's after some track time under my belt.

Thanks for the input!

 

truth be told with those 225 untill u get lots of seat time u can expect lots of spinning and slower times with a rediculous trap speed honestly u may just want to look in to some 24.5 slicks if u really want traction thats just my thought tho

 

To run fast with the bfg's you will definitly want a good boost controller. What ems? The hondata boost control works great.

 

i agree with both above statements
there are lots of things to expect, spinning/wheel hop /axle or diff breakage (worse case)
you need to do really good burn outs (3rd gear)
mid 11s is doable but with great conditions, great track, great weather, and great driving
i went 1144 on 500whp in my eg 2300lbs on centerforce dual friction clutch, (slipping at top end) on 225 bfg s full street trim (with a 1.9 s 60s)

ive also went 1149 w/motor blowing up at top end w/ a 2.1 60ft on 600hp (broke a stock sleeve) and that was with the car all over the place and gettin out of throttle twice since it got very squirrely

make sure u have good mounts/traction bars , good suspension setup, those are the keeps to good 60 and 330 times which are very important on radials (all tires actually) and PRELOAD PRELOAD PRELOAD
(keep in mind u dont want to overpower the tires, and that is what u have to practice find what the car likes and keep doing it) it takes lots of seat time

hope this helps

I have been down the track on BFG's a few times. With that kind of power in a fully int ITR i would expect 11.6 in a cages ITR. there are 2 local ones that float around that area with right around 500whp.

I am sure at least one of them will chime in. If you plan on the 225 your prob going to run out of gear. (if ITR tranny)


2 years ago i made 480whp and when 11.1@130 without a boost controller or any type of preloading. the same year it made 517 and when 11.01@134. *pretty consistantly too...(in a hatch) full int

You just have to be smart learn to drive the **** out of your car! goodluck

 

Totsie, we pretty much have the same set up as far as car weight and hp goes, im also a full interior type r(but add a rolbar) and i made 471hp on 93 octane. my best was an 11.61@130mph with consistant 11.6 times through out the rest of the year.

With the BFG's heat them up good, i do second gear burnouts and ride the clutch off the line a little.its only gonna take practice to really get it down to what works for you, i still spin tires till i hit 3rd gear.

My timeslips and videos are in my sig if you wanted to check them out for a reference or anything.

Everyone thanks very much for you input, it has opened my eyes a lot to things I wasn't considering.

I actually am getting ready to wire up the APEXI AVCR boost controller, and I'm tuned on Neptune with Jeff Evans (scheduled to get tuned April 25th, so I hope I'm done the build in time!) Apparently that boost controller is pretty nice once you learn how to use it properly....

I have the full-race traction bars and a autopower roll cage sitting to install still. I might not get to the traction bars until after it gets tuned, but I won't be beating on a new engine anytime soon anyway. The roll cage I'm considering selling because I'm not too excited about drilling through my car, and might get a higher quality weld-in cage.

DontBlink, thanks for the info man. I was hoping that I could consistantly be around the 11.6-11.8 times on the drag radials, and a more low 11's on slicks if I ever run them. I'll check out your videos and everything. Thanks again

Doesn't Neptune have pwm boost by gear option like hondata? I would rather use that then an AVCR personally.

 

I honestly have no idea if it does or not. Guess I need to talk to Jeff..

 

no need to stage boost at that power level!

 

how much psi are u at when making the 480 whp.

20-21 3" ic pipe stock gsr head .63ar t3/60-1

 

I haven't tuned yet but from similar tunes making in the 460-480 range on pump, I assume I'll be around 16-17 psi

 

i have a similar car as well and i am on bfg but i do no know how a burn out is done in 2nd gear do you guys mind explaining that to me why 2nd and not 1st

second means the tire is spinning at a faster speed so it makes more heat in a shorter amount of time. just the same as a first gear burnout in second.

I never had luck on BFGs at 500whp. my car constantly broke axles but as fmfkid and dont blink said they both did well and I watched them do it manytimes.

I beg to differ. A boost controller with rampable stages like the NLR would be super beneficial. 500ish whp is a lot of power for those tiny drag radials.

 

scott i cant see jeff tuning you to 480 on pump gas with your setup unless you tell him to keep pushing it. but who knows maybe your car will make that power easily, I dont know your exact setup.

i can tell you since we basically have the same setup, that you will spin 1st, spin 2nd, spin 3rd, and probably spin 4th on 225 drag radials. even on the "sticky" track. you need to heat the **** out of those tires. i ran mine around 12psi max. roll thru the burn out box and do your burnout AFTER the box, 2nd gear minimum. being on drag radials and stock axles, as soon as you start to hop, which you most likely will, you are gonna pop an axle. on the street forgettabout wide open throttle. im sure you remember spinning for the win when I took you for a ride. and as already mentioned you will probably have a sick MPH with a slow ET. I went 12.0@127 14psi pump gas full interior with a 2.2 60ft. car weight 2657lbs when i rolled through the scale. i even tried the bigger M/H bias plys and I spun those easily. you are gonna get bored with spinning REAL FAST so either A) get slicks or B) get some solid boost control in lower gears, or C) feather the throttle which is annoying, inconsistent, and basically impossible to control once it starts to spool up. since my setup creeps, even with a 5lb spring, an AVCR is basically useless for gear based boost. im not sure what manifold you have but if you have the same FR ramhorn I do, welcome to boost creep city enjoy your stay

I agree Jeff although Joe had a lot of success with the 225's with just a manual controller I dont see a lot of people having the kind of skill or luck he did

 

I was at the 500whp mark for a season on BFG's and had over 80 passes. I really dont see how a boost controler would help. Just keep it simple. I mean i was consistant 11.0's at norwalk. and 11.1-11.2's @ MIR.
1.8 60's (not that the 60' even matters on a BFG)

thats my input. but with 500 whp your better of spending the money on a diff,hooker or something.

 

well none of this even matters right now haha. No one has these tires in stock near the east coast. There are some on the west, but the cost with shipping isn't worth it. I'd be better off getting slicks to run on the street for a few weeks....

 

I def would not ride around on the street with slicks


Check out a set of the M/T ET Street Drag radials, they offer them in a 225/50/15

 

Yea I was looking at them, but I can't find any consistent reviews on them. How do they compare to BFG's?

 

I have no personally used them, but from what i hear they are an awesome tire for street & track. Not to mention the look sick on the car

Yea I was checking them out last night and they looked very nice. I think this is the route I will go afterall. Had I seen these before in that size I would have already ordered them. I just didn't scroll down the page far enough haha. thanks again man

Which ET drags are you speaking of? Like the ET streets Ben has or the regular Drag Radials? Both the BFG and M/T are good in my book. We have BFG's on our car and like them so far. Just gotta get the launch down a little better.
