Project STI - The Daily Race Car
Discussion
OK so another update.
Roll cage fitted, Safety Devices job, cracking fit and stiffens the car up. This was done a month or so ago, just not got round to updating this.
Next was a set of seats and Harnesses, OMP Champ-R Seats and TRS Magnum Harnesses to be exact. These were fitted on Saturday morning, completed at around 11.30am, I was racing that day which started at 3pm (registration 2pm) and it was 2 hours away, so the fingers were well and truly crossed that I'd put these in correct......and they were all good to go.
Up to now I had only been racing with standard seats and seatbelt. These have made a huge difference in how you can feel the car move. Didn't think they'd play such a big part, but I really wish I'd done this earlier.
Ended up finishing last in class only 0.02 seconds from second last and 3 seconds off the pace.
I may be making excuses here but that was all up against cars which are running upwards of 550bhp (Apart from the one that won who is on 360bhp but is approx 160kg lighter than me and my car) and are not driven on the roads. I'm running 400bhp and use the car a lot. Plus, this is my first season racing the car so not used to it, however, my confidence is growing, but I won't be near the top until I can get myself a transporter, so I don't have to worry about driving the car back from events.

Crikey, seems I've missed a lot out. I have also fitted a set of AP 6 Pot Calipers up front and aim to have the rears in ready for next season.
And have also picked up a nice standard position Owen Developments 650bhp capable turbo which should be going in the car in the next 4-6 weeks. So lets see how that stands me once fitted.

Good on you for having a go- but the front runners in most of those series will take some catching with their very well developed cars especially on the suspension/ chassis front. Good fun trying anyway.
For a race car torque isn't so important and in fact can be an issue ( e.g. you spinning up in second) so if the 2.5 cracks its (thin) liners then a full race 2.1 on a cbd is probably a better bang for your buck with the 2.35 obviously being the best of both worlds.
How do I know? I've had a full race 2.0 rcm engine, followed by a full race 2.1 and now my 1290kg P1 has to drag itself up hills with 2.35/ rotated Gt3582r combo
570bhp / 480ft lb @ 1.8 bar. It's a tad nippy- as you say

I'm never going to be at the top, Olly Clark in the Gobstopper and Andy Forrest in his mental machine put pay to that and I don't have £150k to compete against them.For a race car torque isn't so important and in fact can be an issue ( e.g. you spinning up in second) so if the 2.5 cracks its (thin) liners then a full race 2.1 on a cbd is probably a better bang for your buck with the 2.35 obviously being the best of both worlds.

570bhp / 480ft lb @ 1.8 bar. It's a tad nippy- as you say I'm just doing this for fun and will just eat away at the competition in my class. Once I can take the car on transport, I will make a huge jump. I'm getting more and more confident in the car, only thing holding me back is worrying about how to get home if I bin it.
As a lad in my class said, "Just enjoy yourself, you're not going to win unless you're prepared to bend the Armco"
If the 2.5 lets go then I will have to weigh up my options between a 2.1 and a 2.35 as I already have the turbo for the 2.35, but the 2.1 is a lot cheaper to build, but would need a new turbo
To be honest I wasn't even thinking about the S1 / Pro runners, but anyway as you say the important thing is to have fun and feel like you're improving your times. I know what you mean about how being able to put the remains on a trailor would help you go quicker too.
My 2.1 ran an Md321v turbo /gt30/40 equivalent comfortably - laggy? yes with a high boost threshold, but that's fine for a race car. You didn't notice it on track where you are basically going for it - it was only on the road where you could sometimes get caught out.
It was circa 500bhp / 400ft lb and didn't get going until 4400 or so, but then ran on to 8k rpm.
2.1 can run quite big turbos.
The 2.35/ GT 35 billet is going by 36/3800 and then runs hard into my self imposed limit of 7500, but it feels like it's pretty much ready to go all the time on the road.
It's currently non AVCS, but I have some Cosworth AVCS heads to go on which I must get round to at some point - that should widen the power band a bit more and allow a bigger top end without ruining the low end drivability.

Hi bud, I'd love to see a thread on your car! At 570bhp are you using a 6 speed?For a race car torque isn't so important and in fact can be an issue ( e.g. you spinning up in second) so if the 2.5 cracks its (thin) liners then a full race 2.1 on a cbd is probably a better bang for your buck with the 2.35 obviously being the best of both worlds.

570bhp / 480ft lb @ 1.8 bar. It's a tad nippy- as you say I'm running a fully forged RB5 with a VF37 and support mods on a Alcatek with LC/AL etc. I am planning to turn it up as I'd like to start by moving into the 400's. I've been running this setup for about 10 months and I've loved how the additional power transforms the car into something different.
Ivan, top thread and I hope to see pics/videos and how you get on!
