Now thats impressive give us the spec at that time again paul.

If only i knew what i knew now when i started as id have a 220whp car if not a little more oh an some money still in my pocket, but you learn over time

Well done Paul! Thats a fantastic time without NOS. Is that a vid with NOS?

[Paul@1320]

This is without nitrous, the spec was;

25x9 Toyo slicks
Quaife diff
Exedy Clutch & Flywheel
15% pulley
Newman cam
Janspeed 4-1 manifold and cat
One ball ex mod
Stock IC
Stock injectors
Stock S head and pistons
Tescos 99 fuel
Stock Map

It averaged that day 13.4s @ 100 to be fair (16 runs)

5 weeks later we added a GRS IC and JCW 380cc and it went 13.2s@102

All the above was at 2468lb and no nitrous

Yep, I think you still hold the record Sam , -hardcore . Im still impressed by the guy who drove 500 miles down from Scotland , had a GTT conversion...then back the same day.
ps I'll sort your quote for you in the next couple of days. (hurray he says!)

What kind of benefit would I see with the Exedy Clutch & Flywheel fitted? Would this reduce my 1/4 mile time (14.9 @93 or 94)? Also what gains does the newman cam give typically?

Current spec:

15%pulley
380cc injectors
Works GP i/c
Jcw remap
cat back exhaust Jcw
LSD
Jcw plugs
Jcw air filter (flap still in)

thanks for weighing my car at Santa Pod (2846lb)

Regards

The Exedy clutch would help your et because the stock clutch will slip a bit during the1-2 2-3 3-4 shift, What it will also allow you do which would be more of a benefit, is to run slicks / drag radials / Toyo 888, the stock clutch would not be able to handle a set of slicks hooking up for to many passes.

Unless the clutch is on its way out I would leave it for now and have a Janspeed manifold fitted and do some testing with a grs ic over the works GP ic, we have seen a benefit on the dyno with the grs over the gp ic.

We constantly see a good gain with the cam to a tune of up-to 10hp

It was a pleasure to weigh your car, sorry we didn't get time to speak, hope you haven't become to addicted

Just as a side note today at Santa Pod today 2650lb with a stock engine, grey coated blower, stock pulley, Janspeed manifold, Cooper Borla cat back, quaife diff, Exedy clutch and flywheel, yokoa048 205 50 15 we've just run 14.47 @ 95.5,

Don't forget also for every 100lb of weight saved is equal to 1/10th, cheapest horsepower

Don't forget also it was a very strong headwind at the bmw show, what number were you?

I was #A316. I did enjoy it at Santa Pod but its quite far for me to travel.

I fitted the ebay manifold and decat a few weeks ago but it was so loud I couldn't live with it day to day so I have sold it now. Are you running a high flow cat or decat on the car listed above? What sort of noise increase does the janspeed manifold have over standard or compared to the ebay manifold (i think you have tested one on the dyno, only made about 2.5bhp, correct me if I am wrong)

My clutch is fine for now but was just thinking of the future and how it would benefit me. The only reason I went for the gp i/c is to keep it looking standard/jcw under the bonnet as I have 1 year warranty left .

I am just looking for my next mod and was thinking of the cam but wasn't sure which to go for.

What would you estimate my bhp at with my mods?

James

[Paul@1320]

The janspeed cat does help with noise levels but it'll still be loud, not much use now, but it might of been worth making the main cat from your original manifold fit in place of the de-cat pipec we were going to do that with BigShow but we run out of time, we will be doing this in the future for evaluation.

It didn't make a lot on BigShow car but that was a std engine no pulley etc.

The clutch would definitely benefit you with 60ft of 2.5, with slicks you would gain 4/10ths on a good day.

Next time you come to the Pod we can try our GRS on and see if you can see an improvement .

The cam really needs the header to get the most out of it.

With a best of 94.12mph and at 2846lb your bhp via the wallace calculator is195bhp.

I noticed your mph was inconsistent, did you know the finish line was past the gantry??

If I remember I think I eased off as I just passed the gantry, I'll know for next time, and hopefully can master the start.
